In the aftermath of the Fukushima Daiichi nuclear disaster, [UN Special Rapporteurs have] consistently raised concerns about the approaches taken by the government of Japan. UN Special Rapporteurs have been concerned that raising of “acceptable limits” of radiation exposure to urge resettlement violated the government’s human rights obligations to children.
UN Special Rapporteurs have been concerned of the possible exploitation of migrants and the poor for radioactive decontamination work. Their most recent concern is how the government used the COVID-19 crisis to dramatically accelerate its timeline for deciding whether to dump radioactive wastewater accumulating at Fukushima Daiichi in the ocean
The communities of Fukushima, so devastated by the tragic events of March 11, 2011, have expressed their concerns and opposition to the discharge of the contaminated water into their environment. It is their human right to an environment that allows for living a life in dignity, to enjoy their culture, and to not be exposed deliberately to additional radioactive contamination. Those rights should be fully respected and not be disregarded by the government in Tokyo. The discharge of nuclear waste to the ocean could damage Japan’s international relations. Neighboring countries are already concerned about the release of large volumes of radioactive tritium and other contaminants in the wastewater.
Japan has a duty under international law to prevent transboundary environmental harm. More specifically, under the London Convention, Japan has an obligation to take precaution with the respect to the dumping of waste in the ocean.
Indigenous peoples have an internationally recognized right to free, prior and informed consent. This includes the disposal of waste in their waters and actions that may contaminate their food. No matter how small the Japanese government believes this contamination will be of their water and food, there is an unquestionable obligation to consult with potentially affected indigenous peoples that it has not met…The disaster of 2011 cannot be undone. However, Japan still has an opportunity to minimize the damage…There are grave risks to the livelihoods of fishermen in Japan and also to its international reputation. Again, I urge the Japanese government to think twice about its legacy: as a true champion of human rights and the environment, or not.

Scientists measured microplastics — tiny particles and fibers of plastic that can float in the air like dust — and found that over 1,000 tons a year are falling into wilderness areas and national parks in the western U.S. Janice Brahney of Utah State University and her team identified samples of microplastics and other particulates collected over 14 months in 11 national parks and wilderness areas to create the study published in the journal Science, on June 12, 2020. Pieces of plastic less than 5 mm in length, or microplastics, occur in the environment as a consequence of plastic pollution…
The presence of microplastics in oceans and water supplies has been a matter of concern for some time, but the impact of airborne microplastics is a relatively new area of study. Though microplastics are found nearly everywhere on Earth, the sources and processes behind their ubiquitous distribution, or the “global plastic cycle,” remain vaguely understood. Initially overlooked, recent studies have suggested that long-range atmospheric transport plays an important role in carrying microplastic pollution vast distances and to remote locations…
Examination of weekly wet and monthly dry samples from 11 sites allowed the authors to estimate that more than 1,000 tons of microplastics are deposited onto protected lands in the western U.S. each year, equivalent to more than 123 million plastic water bottles.
The ubiquity of microplastics in the atmosphere has unknown consequences for humans and animals, but the research team observed sizes of particles that were within the ranges that accumulate in lung tissue. Moreover, the accumulation of plastic in the wilderness areas and national parks could well influence the ecosystems in complicated ways.

The Runit Dome is a containment structure on Runit Island, located on Enewetak Atoll. Enewetak Atoll is a former U.S. atmospheric nuclear weapons test site located approximately 2,300 miles west of Hawaii in the northwest Pacific Ocean. The Runit Dome, which was built in the late 1970s, contains over 100,000 cubic yards of contaminated soil and debris [from the US nuclear weapons testing] that were encapsulated in concrete inside an unlined nuclear test crater, the Cactus Crater, on the north end of Runit Island. The site has remained a concern to the people of Enewetak.
The Runit Dome is not in any immediate danger of collapse or failure, and the exterior concrete covering the containment structure is still serving its intended purpose, effectively reducing the natural erosion of the waste pile below by wind and water. Visual surveys of the exterior concrete of the Cactus Crater containment structure have revealed the presence of cracks and spalls in the concrete cap. However, these cracks and spalls in the exterior concrete cap do not form sites for external or internal radiation exposure that impact or endanger human health or the environment, or wildlife.
DOE has performed preventative maintenance on exterior surfaces of the containment structure, which will aid in the determination of any changes that may occur in the condition of the concrete in the future. Any concerns about the imminent failure or collapse of the structure are unfounded.
The main safety concern to humans associated with leakage of radioactive waste from the Cactus Crater containment structure is the uptake of fallout radioactivity in marine foods. There are no data to suggest that the Cactus Crater containment structure, or more specifically, the radioactive material encapsulated in Cactus Crater, is currently having a measurable adverse effect on the surrounding environment or on the health of the people of Enewetak. However, DOE is in the process of establishing a groundwater radiochemical analysis program that is designed to provide scientifically substantiated data that can be used to determine what, if any, effects the dome contents are having, or will have, on the surrounding environment now and in the future.
Long-term trends in the concentration of Pu in lagoon waters derived from retrospective analysis of a coral core collected off Runit Island show levels of Pu in lagoon waters are systematically decreasing. These data provide compelling evidence that the construction of the Runit Dome has had, and continues to have, a negligible impact on the wider marine environment….
The Cactus Crater containment structure remains vulnerable to wave driven over wash and flooding caused by storm surge and potential effects of sea level rise… It is anticipated that any measured or modeled effects of storm events may help provide a better understanding of the long-term consequences of sea-level rise on mass-transport of dome derived radionuclides.
On June 29, 2020 the US Department of Health and Human Services (HHS) announced an agreement to secure large supplies of the drug remdesivir for the United States from Gilead Sciences through September, allowing American hospitals to purchase the drug in amounts allocated by HHS and state health departments….HHS has secured more than 500,000 treatment courses of the drug for American hospitals through September. This represents 100% of Gilead’s projected production for July (94,200 treatment courses), 90% of production in August (174,900 treatment courses), and 90% of production in September (232,800 treatment courses), in addition to an allocation for clinical trials. A treatment course of remdesivir is, on average, 6.25 vials.
Hospitals will receive the product shipped by AmerisourceBergen and will pay no more than Gilead’s Wholesale Acquisition Price (WAC), which amounts to approximately $3,200 per treatment course.

The UN Environment Programme in 2011 proposed the creation of a $1 billion fund to repair the damage done by decades of crude spills in the Ogoniland area in southeastern Nigeria. However, progress has been poor and the little work that has been done is sub-standard, advocacy groups including Amnesty International reported in June 2020. “Research reveals that there is still no clean-up, no fulfillment of ‘emergency’ measures, no transparency and no accountability for the failed efforts, neither by the oil companies nor by the Nigerian government,” the groups said.
Shell’s Nigerian unit pumped oil in Ogoniland until 1993, when the company withdrew amid increasing protests against its presence. Even though the Hague-based company no longer produces crude in the area, a joint venture operated by Shell Petroleum Development Company, or SPDC, still owns pipelines that crisscross the region.
A government agency responsible for overseeing the clean-up, the Hydrocarbon Pollution Remediation Project, known as Hyprep, was finally set up in 2017 after several false starts, but it’s failing to deliver. …“Hyprep is not designed, nor structured, to implement a project as complex and sizable as the Ogoniland clean-up,” the report cites UNEP as saying in 2019
Excerpt from Clean Up Oil in Nigerial Lacks Progress, Bloomberg, June 18,, 2020
The East African Court of Justice delivered in June 2020 a temporary injunction order to the country’s Minister for Justice, the Greater Pioneer Operating Company (GPOC), and the Dar Petroleum Operating Company. The Court approved the application by Hope for Humanity Africa (H4HA), a non-governmental organization (NGO), which sought to highlight the environmental damage caused by oil spills… The NGO contends that: “Over 47,249 of the local population in Upper Nile State and 60,000 in Unity State are at risk of being exposed to the oil pollution this is because the local population depends on the wild foods for survival, the contaminated swamps, streams and rivers waters for cooking, drinking, washing, bathing and fishing.”…
The H4HA is looking for an injunction to stop multiple companies from exporting oil from the region, including CNPC of China, Petronas of Malaysia, and Oil & Natural Gas Corp. of India (ONGC)
Global waste is expected to hit 3.4 billion tons by 2050 from 2.01 billion tons in 2016, according to the World Bank. As recycling programs encounter challenges and landfills in the U.S. and Europe reach capacity or face regulations making them more expensive, incinerators are becoming the most viable option for many municipalities to deal with much of their garbage. England now burns more municipal waste than it recycles or landfills. China—already the world’s biggest trash burner—is building more incinerators. And incineration companies say, for the first time in years, expansion projects are on the table in the U.S., although the industry faces significant legal and community challenges. Overall, incinerator-plant capacity is forecast to rise 43% globally between 2018 and 2028, according to Ecoprog, a consulting firm…..
Another growth driver is a European Union target for member states to cap the amount of municipal trash they send to landfill at 10% by 2030. Local communities and environmental groups have launched strong opposition to expansion of incineration plans, citing environmental and public-health concerns. Incinerator plants are also called waste-to-energy plants since the heat from burning trash is used to generate electricity, and many governments classify that electricity as renewable energy, a characterization opponents dispute…..But advocates for clean energy…say that while some energy is recovered by burning, recycling or composting garbage would save far greater amounts of energy.
Critics also say cities that own their incinerator plants have little incentive to pursue waste-reduction efforts because the plants are designed to run at full capacity. “Many countries are over-investing in incineration to cut down on landfilling, which will eventually lock them into burning,” said Janek Vähk, development and policy coordinator for Zero Waste Europe.

On May 13, Japan’s Nuclear Regulation Authority announced that the nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture, had met new safety standards created after the March 11, 2011, earthquake and tsunami….The Rokkasho plant is a 3.8 million square meter facility designed to reprocess spent nuclear fuel from the nation’s nuclear reactors. Construction began in 1993. Once in operation, the plant’s maximum daily reprocessing capacity will be a cumulative total of 800 tons per year. During reprocessing, uranium and plutonium are extracted, and the Rokkasho plant is expected to generate up to eight tons of plutonium annually.
Both are then turned into a mixed uranium-plutonium oxide (MOX) fuel at a separate MOX fabrication plant, also located in Rokkasho, for use in commercial reactors. Construction on the MOX facility began in 2010 and it’s expected to be completed in 2022. Japan had originally envisioned MOX fuel powering between 16 and 18 of the nation’s 54 commercial reactors that were operating before 2011, in place of conventional uranium. But only four reactors are using it out of the current total of nine officially in operation. MOX fuel is more expensive than conventional uranium fuel, raising questions about how much reprocessed fuel the facilities would need, or want.
The Rokkasho reprocessing plant can store up to 3,000 tons of spent nuclear fuel from the nation’s power plants on-site. It’s nearly full however, with over 2,900 tons of high-level waste already waiting to be reprocessed.
Why has it taken until now for the Rokkasho plant to secure approval from the nuclear watchdog? Decades of technical problems and the new safety standards for nuclear power that went into effect after the 2011 triple meltdown at the power plant in Fukushima Prefecture have delayed Rokkasho’s completion date 24 times so far. It took six years for the plant to win approval under the post-3/11 safety standards…By the time of the NRA announcement on May 13, 2020, the price tag for work at the Rokkasho plant had reached nearly ¥14 trillion.
Japan is the only non-nuclear weapons state pursuing reprocessing. But as far back as the 1970s, as Japan was debating a nuclear reprocessing program, the United States became concerned about a plant producing plutonium that could be used for a nuclear weapons program. The issue was raised at a Feb. 1, 1977, meeting between U.S. Vice President Walter Mondale and Prime Minister Takeo Fukuda. “Reprocessing facilities which could produce weapons grade material are simply bomb factories,” noted a declassified U.S. State Department cable on the meeting. “We want to cooperate (with Japan) to keep the problem under control.”
The U.S. oppose the Rokkasho plant’s construction in 1993, following an agreement in 1988 between the two countries on nuclear cooperation. ..The U.S.-Japan nuclear agreement meant the U.S. would give advance consent for Japan to send spent nuclear fuel to the United Kingdom and France — states with nuclear weapons — for reprocessing until Rokkasho was running at full-scale.
Currently, Japan has nearly 45 tons of plutonium stockpiled, including 9 tons held by domestic utilities. Another 21.2 tons is in the United Kingdom and France is holding 15.5 tons under overseas reprocessing contracts.
Thus, Japan finds itself caught between promises to the international community to reduce its plutonium stockpile through reprocessing at Rokkasho, and questions about whether MOX is still an economically, and politically, viable resource — given the expenses involved and the availability of other fossil fuel and renewable energy resources.

Around the world officials are advising people to be wary of alternative treatments for covid-19. The opposite is true in China, where remedies known as traditional Chinese medicine (TCM) are being heavily promoted by the state. In January 2020, as the crisis escalated, the health ministry listed TCM treatments among those it recommended for the disease. It sent nearly 5,000 specialists to Hubei to administer them to patients (including sufferers at a sports centre in Wuhan that was turned into a TCM hospital for people with mild symptoms). Now China is keen to promote its remedies abroad. TCM practitioners have joined Chinese medical teams sent to help manage outbreaks in Cambodia, Iraq and Italy. In mid-March, 2020 state media quoted a Tanzanian health official saying that China’s use of TCM for covid-19 may be “a model” for Africa to follow…
The use of animals in TCM sometimes involves appalling cruelty. One of the TCM remedies that the health ministry has recommended for use in the treatment of covid-19 patients includes powdered bear bile. In China this is often extracted from live bears kept in grim farms even though its active ingredient can be created synthetically. In February 2020 China banned the sale of wild animals as food—close contact in markets between live specimens and merchants may have helped the coronavirus to leap from animal to human. But the new rules do not prevent trappers and breeders from selling animal parts for use in TCM.
Officials do not say that traditional remedies can cure covid-19. But they do claim that TCM can reduce death rates by preventing patients with mild or moderate symptoms from developing more serious ones. They also say that TCM can speed up recovery. A website set up by China Daily, a state newspaper, called “Fighting covid-19 the Chinese way”, says that TCM can “remove the trash which causes illness”, leaving the virus “no room to survive”.

Plastic bags may make a temporary comback in some places because of COVID-19. In a setback, albeit temporary, for efforts to combat plastic waste, many state and local governments have suspended plastic bag bans and are prohibiting the use of reusable bags to stem the spread of COVID-19. The plastics industry is pushing for such measures, causing environmentalists to cry foul. San Francisco, which has been at the forefront of single-use plastics restrictions, issued an order “not permitting customers to bring their own bags, mugs, or other reusable items from home” as a measure “to prevent unnecessary contact.” Maine is delaying enforcement of its plastic bag ban to Jan. 15, 2021, after originally planning to roll it out on April 22—Earth Day….
The plastics industry has been advocating for such measures. In recent weeks, Bag The Ban, an initiative sponsored by the American Recyclable Plastic Bag Alliance, has endorsed editorials in newspapers such as the Boston Herald and the New Hampshire Union Leader advocating use of plastic bags to protect grocery workers from COVID-19.
Writing to the US Department of Health and Human Services, the Plastics Industry Association made a similar point. “Single-use plastic products are the most sanitary choice when it comes to many applications.” The association cited research on reusable bags, including a 2011 study from Loma Linda University and the University of Arizona that tested bags from shoppers selected randomly at the grocery store and found bacteria such as E. coli on 8% of them. It also pointed to a 2012 outbreak of norovirus in Oregon linked to use of a reusable food bag and cited a 2019 study from Portugal that found bacteria in bags.

From Europe to South America, U.S. allies are complaining about the superpower’s “Wild West” tactics in outbidding or blocking shipments to buyers who have already signed deals for vital medical supplies. …”Money is irrelevant. They pay any price because they are desperate,” one high-level official in German Chancellor Angela Merkel’s ruling CDU/CSU group told Reuters….In April 5, 2020, US President Trump said he was signing a directive to stop the export of N95 respirator masks, which provide essential protection for health-care workers, and other U.S. medical equipment. Furthermore, 3M, a US company, said that the White House had ordered it to stop all shipments to Canada and Latin America of respirators that it manufactures in the U.S., despite what 3M called “significant humanitarian implications.”
In another case, an order of 200,000 masks bound for Germany was diverted to the U.S….Germany’s Secretary of Interior Andreas Geisel called it an “act of modern piracy.” He stated that: “even in times of global crisis, you shouldn’t use Wild West methods.”

“We don’t have a national plan,” says epidemiologist Michael Osterholm of the University of Minnesota, Twin Cities. “We are going from press conference to press conference and crisis to crisis … trying to understand our response.”…Even if lockdowns succeed at halting the virus…. the United States needs to marshal massive resources to monitor for new outbreaks and quickly contain them…. Identifying cases and contacts and isolating them will require a huge increase in public health workers at the local level….The absence of nationwide coordination highlights the division of legal power between the federal and state governments…. Governors, not federal officials, typically hold police powers to shut businesses and enforce curfews. But many are reluctant to invoke those powers and suffer the political costs without clear direction from above….“The closest comparison here, in terms of national mobilization, is a war. And there is no way the United States would fight a war as 50 separate states.”

A common fixture in refrigerators, furniture and footwear, polyurethane plastic is pretty much always in high demand. Humans worldwide cycle through millions of tons of the durable substance each year, sending the bulk of what’s not recycled to garbage dumps, where it leaks toxic chemicals into the environment as it very slowly breaks down. At least one of Earth’s organisms sees the stuff as a boon: a bacterial strain called Pseudomonas sp.TDA1. This polyurethane-munching microbe seems to thrive in waste dump sites. Studying the Pseudomonas strain and the chemical strategies it deploys could someday help researchers put a small dent in the world’s plastic problem, which has cumulatively saddled the planet with more than 8 billion tons of slow-degrading synthetic material.
Pseudomonas sp. TDA1 is one of only a few microbes known to be tolerant to polyurethane plastic’s typically toxic properties. What’s more, the bacteria doesn’t just withstand the plastic’s harsh ingredients: it uses some of them as a food source… But while the bacterium can metabolize a subset of the chemicals in polyurethane plastic, it doesn’t seem able to break down these products completely. In-depth studies of Pseudomonas sp. TDA1 will reveal the genes crucial to these plastic-attacking abilities. Understanding how these genes and their products work could help scientists engineer synthetic approaches to tackling plastic in the future.

The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.
The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

During the Gulf war of 1991, no fewer than 117,000 landmines were showered over Kuwait and Iraq by American planes. This barely dented the Pentagon’s vast stockpile of 19m. Just under a quarter of the devices scattered in the path of Saddam Hussein’s army were anti-personnel landmines (APLs), the sort that would soon be banned by the Anti-Personnel Mine Ban Convention of 1997, widely known as the Ottawa treaty. The Ottawa treaty has 164 parties, all of which ban the production and use of APL (anti-vehicle mines, among others, are still allowed). America is not among them. When the treaty was finalised, America declined to join (other holdouts include China, Cuba, Iran, Russia and Syria).
Landmines have a number of military uses. They are typically used to channel opposing armies away from particular areas and into others. A minefield can force an enemy to turn, which exposes their flank and makes them especially vulnerable, says Vincent Brooks, a retired general who commanded American forces in South Korea in 2016-18. They can also be used to “canalise” the enemy, channelling attackers into unfavourable terrain, where they may be more exposed to concentrated artillery fire. …But landmines are reviled weapons, and not without good reason. “They’re indiscriminate,”… Landmine casualties have fallen sharply over the years, but at least 2,000 people were killed or wounded by manufactured or improvised APLS in 2018, according to data collected by the Landmine and Cluster Munition Monitor, a research group. Laying a mine can cost a few dollars; clearing one can require $1,000.
The Pentagon has an answer to this. It says that it only possesses, would only produce and would only use “non-persistent” landmines with the capacity to self-destruct or, failing that, to self-deactivate, with a battery losing its charge, within 30 days (some models can blow themselves up in as little as a few hours). It claims that such features are remarkably reliable. …“When the technology is brought into the battlefield, we see that the actual data doesn’t match with the promises,” says Erik Tollefsen, head of Weapons Contamination for the International Committee of the Red Cross. He says that impressive reliability rates are usually derived from tests in sterile conditions, and prove wildly exaggerated in practice. In 2002 a report by the Government Accountability Office, an agency that audits the federal government, noted that during the Gulf war one in 10,000 mines were expected to remain active, which would have produced 12 duds. The actual figure was almost 2,000.
Others argue that there are perfectly viable alternatives to APLs….In particular, remotely activated mines (rather than victim-activated ones) are allowed under the treaty if the person triggering the device has the would-be victim in sight, although this makes them harder to use at range and hostage to a breakdown of communications. In 2018 Finland—a late and reluctant signatory to Ottawa, given its long border with Russia—said it was developing a new, remote-controlled variety of anti-personnel “bounding” mine that leaps into the air and fires metal bullets downward.
Excerpts from Ethical Landmines: Watch Your Step, Economist, Feb. 15, 2020
Substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure. Such materials include cobalt, copper, lithium, cadmium, and rare earth elements (REEs)—needed for technologies such as solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors…A majority of the world’s cobalt is mined in the Democratic Republic of Congo (DRC), a country struggling to recover from years of armed conflict…Owing to a lack of preventative strategies and measures such as drilling with water and proper exhaust ventilation, many cobalt miners have extremely high levels of toxic metals in their body and are at risk of developing respiratory illness, heart disease, or cancer.
In addition, mining frequently results in severe environmental impacts and community dislocation. Moreover, metal production itself is energy intensive and difficult to decarbonize. Mining for copper,and mining for lithium has been criticized in Chile for depleting local groundwater resources across the Atacama Desert, destroying fragile ecosystems, and converting meadows and lagoons into salt flats. The extraction, crushing, refining, and processing of cadmium can pose risks such as groundwater or food contamination or worker exposure to hazardous chemicals. REE extraction in China has resulted threatens rural groundwater aquifers as well as rivers and streams.
Although large-scale mining is often economically efficient, it has limited employment potential, only set to worsen with the recent arrival of fully automated mines. Even where there is relative political stability and stricter regulatory regimes in place, there can still be serious environmental failures, as exemplified by the recent global rise in dam failures at settling ponds for mine tailings. The level of distrust of extractive industries has even led to countrywide moratoria on all new mining projects, such as in El Salvador and the Philippines.
Traditional labor-intensive mechanisms of mining that involve less mechanization are called artisanal and small-scale mining (ASM). Although ASM is not immune from poor governance or environmental harm, it provides livelihood potential for at least 40 million people worldwide…. It is also usually more strongly embedded in local and national economies than foreign-owned, large-scale mining, with a greater level of value retained and distributed within the country. Diversifying mineral supply chains to allow for greater coexistence of small- and large-scale operations is needed. Yet, efforts to incorporate artisanal miners into the formal economy have often resulted in a scarcity of permits awarded, exorbitant costs for miners to legalize their operations, and extremely lengthy and bureaucratic processes for registration….There needs to be a focus on policies that recognize ASM’s livelihood potential in areas of extreme poverty. The recent decision of the London Metals Exchange to have a policy of “nondiscrimination” toward ASM is a positive sign in this regard.
A great deal of attention has focused on fostering transparency and accountability of mineral mining by means of voluntary traceability or even “ethical minerals” schemes. International groups, including Amnesty International, the United Nations, and the Organisation for Economic Co-operation and Development, have all called on mining companies to ensure that supply chains are not sourced from mines that involve illegal labor and/or child labor.
Traceability schemes, however, may be impossible to fully enforce in practice and could, in the extreme, merely become an exercise in public relations rather than improved governance and outcomes for miners…. Paramount among these is an acknowledgment that traceability schemes offer a largely technical solution to profoundly political problems and that these political issues cannot be circumvented or ignored if meaningful solutions for workers are to be found. Traceability schemes ultimately will have value if the market and consumers trust their authenticity and there are few potential opportunities for leakage in the system…
Extended producer responsibility (EPR) is a framework that stipulates that producers are responsible for the entire lifespan of a product, including at the end of its usefulness. EPR would, in particular, shift responsibility for collecting the valuable resource streams and materials inside used electronics from users or waste managers to the companies that produce the devices. EPR holds producers responsible for their products at the end of their useful life and encourages durability, extended product lifetimes, and designs that are easy to reuse, repair, or recover materials from. A successful EPR program known as PV Cycle has been in place in Europe for photovoltaics for about a decade and has helped drive a new market in used photovoltaics that has seen 30,000 metric tons of material recycled.

Nuclear and other radioactive material is hardest to protect when it is transported from point A to point B — more than half of the incidents of theft of radioactive material reported to the IAEA between 1993 and 2019 occurred while it was in transport.
Around 20 million shipments of nuclear and other radioactive material are regularly transported within countries and across borders each year. These materials are used in industry, agriculture and medicine, as well as in education. Some of them are also radioactive sources that are no longer useful, known as disused sources.
The aim of nuclear security during transport is to ensure that the material is secured throughout and that it is not used for criminal or malicious purposes. While the level of security differs depending on the sensitivity of the material, the fundamental elements of secure transport include physical protection, administrative measures, training and protection of information about the transport routes and schedule. In some cases, escort personnel may also need to be armed…
“During conversion of our research reactor from high enriched to low enriched uranium fuel, we had to transport highly radioactive spent reactor fuel from the site to the airport to be sent back to the original manufacturer, and we had to transport the new low enriched uranium fuel from the airport to the facility,” said Yusuf A. Ahmed, Director of the Centre for Energy Research and Training in Nigeria, who was involved in the conversion project. “Although the transport time is only a few hours, there is a lot that can happen during that time, from simple traffic accidents to malicious interventions and sabotage of shipments.”
While only around 30 countries use nuclear power and therefore have significant amounts of nuclear materials to transport, almost all countries use radioactive sources.

The decades-overdue clean-up of Ogoniland, after years of oil spills from the pipelines that criss-cross the region, is finally under way. But the billion-dollar project — funded by Nigeria’s national oil company and Royal Dutch Shell — is mired in allegations of corruption and mismanagement. “We are not pleased with what is going on,” said Mike Karikpo, an attorney with Friends of the Earth International and a member of the Ogoniland team that negotiated the creation of the Hydrocarbon Pollution Remediation Project (Hyprep), the government body running the clean-up…
Nigeria is Africa’s biggest oil producer, pumping out about 1.8m barrels per day. It provides roughly 90 per cent of the country’s foreign exchange and more than half of government revenues. The clean-up began only the summer 2019, about a year after the first of an expected five tranches of $180m in funding was released to Hyprep. Mr Karikpo complains of a lack of transparency, alleging that planning, budgeting and awarding of contracts took place behind closed doors. Work started at the height of the rainy season, washing away much of the progress as contaminated soil collected for treatment was swept back into the environment…
Ogoniland, like the broader Niger Delta, has become more polluted and development has stalled, with little to show for the billions of dollars in crude that has been extracted. Critics have now accused Hyprep of being, like much of Nigeria’s oil sector, a vehicle for political patronage and graft. This year 16 companies were awarded contracts for the first phase of the clean-up, which — to the consternation of critics — focuses on the least contaminated parts of Ogoniland.
An investigation by the news site Premium Times found that almost all the companies were set up for other purposes, including poultry farming, car sales and construction, and had no experience of tackling oil pollution. Meanwhile, insiders have questioned Hyprep’s capacity to handle such a massive project…
Shell and Hyprep have rejected the criticism. Shell, which closed its Ogoniland operations in 1993, said it accepted responsibility “for spills arising from its operations”, but that some of the blame for the pollution must go to thieves who illegally tapped into pipelines and makeshift refining operations in the Delta’s creeks

The federal agency overseeing oil and gas operations in the Gulf of Mexico after hurricane Katrina reported that more than 400 pipelines and 100 drilling platforms were damaged. The U.S. Coast Guard, the first responder for oil spills, received 540 separate reports of spills into Louisiana waters. Officials estimated that, taken together, those leaks released the same amount of oil that the highly publicized 1989 Exxon Valdez disaster spilled into Alaska’s Prince William Sound — about 10.8 million gallons…
While hurricanes gain speed due to the effects of climate change, the push for oil leasing in the Gulf of Mexico shows no sign of slowing down. In 2014, the Obama administration opened up 40 million new acres in the Gulf for oil and gas development. Four years later, the Trump administration announced plans to open up most of the rest, in what would be the largest expansion of offshore oil and gas drilling in U.S. history. Many of these 76 million acres are to be offered at reduced royalty rates to encourage additional near-shore drilling in Louisiana waters…
“In the Gulf, storms are predicted to be less frequent but more intense when they do come,” said Sunshine Van Bael, an ecologist at Tulane University who evaluated damage to marsh ecosystems from the BP oil spill. “One thing that storms do is, if oil has been buried underneath the marsh because it wasn’t rehabilitated, a storm could come along and whip that back up to the surface. So, the aftereffects of the oil spills might be greater [with climate change] since the storms are predicted to be more intense.”…
In 2009, a class-action lawsuit against Murphy Oil Corp. ended in a settlement requiring the company to pay $330 million to 6,200 claimants, including owners of about 1,800 homes in St. Bernard Parish. The damage occurred when one of Murphy’s storage tanks floated off its foundation during Katrina and dumped over a million gallons of crude oil into a square-mile segment of Meraux and Chalmette….
To date, more than $19 million has been paid out from the federal Oil Spill Liability Trust Fund to reimburse at least two oil companies for costs they incurred cleaning up oil they spilled during Katrina…
“We don’t normally penalize [companies] for act of God events,” Greg Langley of the Department of Environmental Quality said. “We just get right to remediation.”

E-waste is the fastest-growing element of the world’s domestic waste stream, according to a 2017 report by the UN’s Global E-waste Monitor. Some 50m metric tonnes will be produced annually in 2020 — about 7kg for every person in the world. Just 20 per cent will be collected and recycled. The rest is undocumented, meaning it likely ends up in landfill, incinerated, traded illegally or processed in a substandard way. That means hazardous substances spilling into the environment, poisoning the ground and people living nearby.
Heavy metals such as mercury, lead and cadmium — commonly found in LCD screens, refrigerators and air-conditioning units — as well as chemicals such as CFCs and flame retardants found in plastics can contaminate soil, pollute water and enter the food chain. Research last year by Basel Action Network, an NGO, linked toxic e-waste shipped from Europe to contaminated chicken eggs in Agbogbloshie — a Ghanaian scrapyard where 80,000 residents subsist by retrieving metals from electrical waste. Eating just one egg from a hen foraging in the scrapyard would exceed the European Food Safety Authority’s tolerable daily intake for chlorinated dioxins 220-fold.
Some appliances are more likely to be recycled than others. The recycling rate for big appliances, such as fridges and cookers, is about 80 per cent. That is because they are harder to dispose of and eventually get picked up, even when they are dumped by the kerb. Of small appliances, however, barely one in five makes it to the recycling centre. Across the world, governments are trying different ways to reduce e-waste and limit the amount that ends up in landfill.
For some time, EU countries have operated a one-for-one take-back system — which means that distributors need to take back, for free, an older version of any equipment they sell you. But since the rapid rise of online retailers, this has been harder to implement
In the end, all e-waste needs to be reduced to core metals. “It’s a bit like a mining activity.” In certain recycling plants robots have been programmed to dismantle flatscreen TVs, extracting precious metals such as cobalt or lithium, whose deposits are limited and increasingly valuable. “One of the hardest things about recycling is that you are not sure how [the manufacturers] made it.” Companies are encouraged to include this information on their devices. It could be a file with instructions readable by robots that could then proceed with the dismantling, making the process “easier, cheaper and more circular”. However, manufacturers have so far kept a close guard on the design of their products.
Many pressure groups and lawmakers have concluded that improving recycling rates will not be sufficient to tackle the global e-waste problem. Increasingly, they are advocating for the right to repair. In October 2019, the EU adopted a package of design measures to make household appliances more repairable. Starting from March 2021, manufacturers selling certain household appliances will have to ensure that spare parts are available for a number of years after their product has launched; that their items can be easily disassembled (and so use screws not glue); and that they provide access to technical information to repair professionals.
The rules cover appliances including refrigerators, washing machines, dishwashers and televisions. But they do not extend to IT equipment such as laptops, tablets and mobile phones. “The road to a new product is very easy, and the road to a successful repair very difficult,” says Martine Postma, founder and director of Repair Café International Foundation, which celebrated its 10th anniversary last year. Since its first repair event in Amsterdam in 2009, the organisation has grown to nearly 2,000 repair groups in 35 countries around the world. Now, it wants to collect more data about electronic gadgets, to see if it can plot “weak points” in design that could help manufacturers make them more repairable.
Excerpts from Aleksandra Wisniewska, What happens to your old laptop? The growing problem of e-waste, http://wiki.ban.org, Jan. 10, 2020
A salty substance called “brine,” is a naturally occurring waste product that gushes out of America’s oil-and-gas wells to the tune of nearly 1 trillion gallons a year, enough to flood Manhattan, almost shin-high, every single day. At most wells, far more brine is produced than oil or gas, as much as 10 times more. Brine collects in tanks, and workers pick it up and haul it off to treatment plants or injection wells, where it’s disposed of by being shot back into the earth…
The Earth’s crust is in fact peppered with radioactive elements that concentrate deep underground in oil-and-gas-bearing layers. This radioactivity is often pulled to the surface when oil and gas is extracted — carried largely in the brine…
Radium, typically the most abundant radionuclide in brine, is often measured in picocuries per liter of substance and is so dangerous it’s subject to tight restrictions even at hazardous-waste sites. The most common isotopes are radium-226 and radium-228, and the Nuclear Regulatory Commission requires industrial discharges to remain below 60 for each. Some brine samples registered combined radium levels above 3,500, and one was more than 8,500. “It’s ridiculous that those who haul brine are not being told what’s in their trucks,” says John Stolz, Duquesne’s environmental-center director. “And this stuff is on every corner — it is in neighborhoods. Truckers don’t know they’re being exposed to radioactive waste, nor are they being provided with protective clothing.
“Breathing in this stuff and ingesting it are the worst types of exposure,” Stolz continues. “You are irradiating your tissues from the inside out.” The radioactive particles fired off by radium can be blocked by the skin, but radium readily attaches to dust, making it easy to accidentally inhale or ingest. Once inside the body, its insidious effects accumulate with each exposure. It is known as a “bone seeker” because it can be incorporated into the skeleton and cause bone cancers called sarcomas. It also decays into a series of other radioactive elements, called “daughters.” The first one for radium-226 is radon, a radioactive gas and the second-leading cause of lung cancer in the U.S. Radon has also been linked to chronic lymphocytic leukemia.
Oil fields across the country — from the Bakken in North Dakota to the Permian in Texas — have been found to produce brine that is highly radioactive. “All oil-field workers,” says Fairlie, “are radiation workers.” But they don’t necessarily know it.
The advent of the fracking boom in the early 2000s expanded the danger, saddling the industry with an even larger tidal wave of waste to dispose of, and creating new exposure risks as drilling moved into people’s backyards. “In the old days, wells weren’t really close to population centers. Now, there is no separation,” says City University of New York public-health expert Elizabeth Geltman. In the eastern U.S. “we are seeing astronomically more wells going up,” she says, “and we can drill closer to populations because regulations allow it.” As of 2016, fracking accounted for more than two-thirds of all new U.S. wells, according to the Energy Information Administration. There are about 1 million active oil-and-gas wells, across 33 states, with some of the biggest growth happening in the most radioactive formation — the Marcellus. …
There is little public awareness of this enormous waste stream, the disposal of which could present dangers at every step — from being transported along America’s highways in unmarked trucks; handled by workers who are often misinformed and underprotected; leaked into waterways; and stored in dumps that are not equipped to contain the toxicity. Brine has even been used in commercial products sold at hardware stores and is spread on local roads as a de-icer…
But a set of recent legal cases argues a direct connection to occupational exposure can be made… Pipe cleaners, welders, roughnecks, roustabouts, derrickmen, and truck drivers hauling dirty pipes and sludge all were exposed to radioactivity without their knowledge and suffered a litany of lethal cancers. An analysis program developed by the Centers for Disease Control and Prevention determined with up to 99 percent certainty that the cancers came from exposure to radioactivity on the job, including inhaling dust and radioactivity accumulated on the workplace floor, known as “groundshine.”
“Almost all materials of interest and use to the petroleum industry contain measurable quantities of radionuclides,” states a never-publicly released 1982 report by the American Petroleum Institute, the industry’s principal trade group, passed to Rolling Stone by a former state regulator. Rolling Stone discovered a handful of other industry reports and articles that raised concerns about liability for workers’ health. A 1950 document from Shell Oil warned of a potential connection between radioactive substances and cancer of the “bone and bone marrow.” In a 1991 paper, scientists with Chevron said, “Issues such as risk to workers or the general public…must be addressed.”
“There is no one federal agency that specifically regulates the radioactivity brought to the surface by oil-and-gas development,” an EPA representative says. In fact, thanks to a single exemption the industry received from the EPA in 1980, the streams of waste generated at oil-and-gas wells — all of which could be radioactive and hazardous to humans — are not required to be handled as hazardous waste. In 1988, the EPA assessed the exemption — called the Bentsen and Bevill amendments, part of the Resource Conservation and Recovery Act — and claimed that “potential risk to human health and the environment were small,” even though the agency found concerning levels of lead, arsenic, barium, and uranium, and admitted that it did not assess many of the major potential risks. Instead, the report focused on the financial and regulatory burdens, determining that formally labeling the “billions of barrels of waste” as hazardous would “cause a severe economic impact on the industry.”…
There is a perception that because the radioactivity is naturally occurring it’s less harmful (the industry and regulators almost exclusively call oil-and-gas waste NORM — naturally occurring radioactive material, or TENORM for the “technologically enhanced” concentrations of radioactivity that accumulate in equipment like pipes and trucks.”…
In Pennsylvania, regulators revealed in 2012 that for at least six years one hauling company had been dumping brine into abandoned mine shafts. In 2014, Benedict Lupo, owner of a Youngstown, Ohio, company that hauled fracking waste, was sentenced to 28 months in prison for directing his employees to dump tens of thousands of gallons of brine into a storm drain that emptied into a creek that feeds into the Mahoning River. While large bodies of water like lakes and rivers can dilute radium, Penn State researchers have shown that in streams and creeks, radium can build up in sediment to levels that are hundreds of times more radioactive than the limit for topsoil at Superfund sites. Texas-based researcher Zac Hildenbrand has shown that brine also contains volatile organics such as the carcinogen benzene, heavy metals, and toxic levels of salt, while fracked brine contains a host of additional hazardous chemicals. “It is one of the most complex mixtures on the planet,” he says…
“There is nothing to remediate it with,” says Avner Vengosh, a Duke University geochemist. “The high radioactivity in the soil at some of these sites will stay forever.” Radium-226 has a half-life of 1,600 years. The level of uptake into agricultural crops grown in contaminated soil is unknown because it hasn’t been adequately studied.
“Not much research has been done on this,” says Bill Burgos, an environmental engineer at Penn State who co-authored a bombshell 2018 paper in Environmental Science & Technology that examined the health effects of applying oil-field brine to roads. Regulators defend the practice by pointing out that only brine from conventional wells is spread on roads, as opposed to fracked wells. But conventional-well brine can be every bit as radioactive, and Burgos’ paper found it contained not just radium, but cadmium, benzene, and arsenic, all known human carcinogens, along with lead, which can cause kidney and brain damage.
Ohio, because of its geology, favorable regulations, and nearness to drilling hot spots in the Marcellus, has become a preferred location for injection wells. Pennsylvania has about a dozen wells; West Virginia has just over 50. Ohio has 225. About 95 percent of brine was disposed of through injection as of 2014. Government scientists have increasingly linked the practice to earthquakes, and the public has become more and more suspicious of the sites. Still, the relentless waste stream means new permits are issued all the time, and the industry is also hauling brine to treatment plants that attempt to remove the toxic and radioactive elements so the liquid can be used to frack new wells.
Excerpts from America’s Radioactive Secret, Rolling Stone Magazine, Jan. 21, 2020
Thirty years in the making, RTS,S, the malaria vaccine, also known by its brand name, Mosquirix, targets Plasmodium falciparum, the most common and most lethal of four malaria parasite species. It is an answer to a dire need. After decades of declining numbers of cases and deaths, the fight against malaria has stalled. Parasites resistant to the most widely used treatment, called artemisinin-based combination therapy, are spreading, while malaria mosquitoes are increasingly resistant to insecticides. And yet the rollout in Malawi and in two other African countries, isn’t quite the breakthrough the field has been waiting for. Mosquirix’s efficacy and durability are mediocre: Four doses offer only 30% protection against severe malaria, for no more than 4 years. Some experts question whether that is worth the cost and effort.
The biggest concerns, however, are about the vaccine’s safety. In the largest trial, children who received Mosquirix had a risk of meningitis 10 times higher than those who received a control vaccine. Mosquirix may not have triggered the meningitis cases—there are other possible explanations—but the possible risk worried the global health community so much that, rather than rolling out the vaccine across Africa, the World Health Organization (WHO) has decided to set up a pilot in Malawi, Ghana, and Kenya in which the vaccine will be given to hundreds of thousands of children.
The Malaria parasite is a challenging target for a vaccine. It has a complex life cycle that begins when an infected female mosquito bites a human and spits Plasmodium cells called sporozoites into the bloodstream. They multiply in the liver, emerge as another cell type named merozoites, invade red blood cells, and continue to multiply. The blood cells burst, causing fever, headache, chills, muscle aches, and often anemia. (They also flood the blood with gametocytes—the parasite’s reproductive cells—ready to be picked up by the next mosquito.) Along the way, the parasite frequently changes its surface proteins. That makes it an elusive target for the immune system, and for a vaccine.
Mosquirix, developed in the 1980s by a team in Belgium at SmithKline-RIT, now part of GlaxoSmithKline (GSK), stimulates an immune response against a protein that occurs only on the sporozoites’ surface. To bolster the response, the research team fused the vaccine protein with a hepatitis B surface protein and added an adjuvant….
A relative outside, Danish anthropologist and vaccine researcher Peter Aaby of the Bandim Health Project in Guinea-Bissau, offered another argument against introduction. After reanalyzing the data from the biggest trial, Aaby discovered that although the vaccinated children had malaria less often, they did not die less often. Among girls, overall mortality was almost doubled, Aaby told his colleagues at the meeting. “This vaccine is killing girls,” he recalls saying. Whereas WHO expects the vaccine to save one life per 200 children vaccinated, Aaby believes one in 200 will die as a result of it; he predicts “a nightmare.”
Aaby and Christine Stabell Benn, a global health professor at the University of Southern Denmark, have an explanation. The married couple has studied routine vaccinations in Africa for decades and believes vaccines can “train” the immune system in ways that don’t affect just the target disease. Vaccines that contain a living, weakened pathogen—such as the vaccines against measles and tuberculosis—strengthen the immune system generally, Aaby and Stabell Benn say, making recipients better able to fight off other infections. But vaccines that contain a killed pathogen or only bits of it weaken the immune system, their theory goes—especially in girls, because their immune systems seem to respond more strongly to vaccines in general.
Excerpts from Jop de Vrieze, A Shot of Hope, Science Magazine, Nov. 29, 2019, at 1063
An increase in the number of teens and young adults diagnosed with a rare cancer in the southwest corner of Pennsylvania has caused the state to look for a link between fracking and the disease.The investigation was sparked by a spate of Ewing’s sarcoma cases in and around Washington County, which has more Marcellus Shale gas wells than any other county in the state. In April 2019 state Department of Health found that the cases didn’t constitute a statistically significant cancer cluster. But affected families and other residents lobbied the governor for an investigation.
The region is home to coal mining, oil drilling, chemical plants and a former uranium-processing facility. Each year, about 250 children in the U.S. are diagnosed with Ewing’s sarcoma, a rare cancer of the bone or surrounding soft tissue, according to the National Institutes of Health. In four counties in southwest Pennsylvania, 31 people were diagnosed with Ewing’s sarcoma from 2006 through 2017, according to state cancer data. That is a roughly 40% increase from the period from 1995 through 2005, when 22 people in the same area were diagnosed, according to state data. Residents point to two additional cases in 2018. Most troubling to many local residents is that the six cases in Washington County since 2008 occurred in one school district.
Other communities are studying potential health risks of fracking. In October 2019, Colorado regulators said they would tighten regulation of drilling after a state-funded study found that people living within 2,000 feet of oil-and-gas wells could have, in worst-case scenarios, an elevated risk for infrequent, short-term health effects such as nosebleeds and headaches from emissions.
Evelyn Talbott, a professor of epidemiology at the University of Pittsburgh, said Pennsylvania investigators should look at residents’ potential exposures to chemicals and to radiation from natural-gas sites. She said they also should look at the sealed waste site of the defunct uranium-processing plant…Since Pennsylvania’s first Marcellus Shale well was drilled in Washington County in 2003, more than 1,800 wells have been fracked there. Compressor stations, processing plants and pipelines have followed. Some residents worry that pollutants such as benzene from air emissions or radium from wastewater could affect people’s health.
According to a report, published on December 4th, 2019 by the World Health Organization, there were 228 million cases of malaria in 2018, which resulted in 400,000 deaths. Most victims were young children in Africa. That is a far cry from targets set in 2015 for the near-elimination of malaria by 2030. These targets depended on a $6 billion a year being poured into malaria-control efforts. Funding in recent years, however, has been about $3 billion a year. More money would surely help. But substantial gains can be made by doing things more efficiently—something at which malaria programmes have been dismal.
Stopping malaria relies on three things: insecticide-treated bed nets to prevent nocturnal mosquito bites; the spraying of homes with insecticides; and the treating of pregnant women and children with rounds of preventive medication. These are all “imperfect tools, often used imperfectly”, says Pedro Alonso, head of the malaria programme at the World Health Organisation. Countries usually deploy the same package of measures everywhere, even though infection rates and their seasonal patterns vary a lot between regions, and particularly between cities and the countryside. Transmission reaches a peak in the rainy season, when mosquitoes are abundant, so preventive mass-treatment of children then can make a huge difference. Regional variations are particularly pronounced in large countries like Nigeria—a place that, by itself, accounts for a quarter of the world’s malaria cases.
The typical approach of a malaria-control programme is to bombard a country with bed nets and then use whatever cash remains for sporadic rounds of preventive medication. But in many big cities, such as Dar es Salaam and Nairobi, cases are few and far between, so deploying nets there is a waste. Overspending on nets at the expense of other things happens partly because nets are easy to count—a feature that aid programmes are particularly fond of. Results which cannot be attributed directly to money a donor spends tend to fall further down that donor’s list of priorities. This kind of reasoning tips the scales, because foreign aid accounts for two-thirds of the money spent on malaria.

Less than half of the world’s larger miners have released safety and environmental details about their mine-waste dams, showing the mixed success of investors’ demands for greater transparency after the deadly Brumadinho dam collapse in Brazil. In January, 2019, 270 people died following the collapse of a tailings dam owned by Brazil’s Vale SA. The incident prompted a coalition of investors who manage more than $13 trillion to ask 726 companies in the mining and oil-sands business to disclose information on their dams. Nearly 55% of companies hadn’t delivered as of November 2019. While some of the largest miners—including Vale, BHP , and Anglo American have disclosed their information, others have yet to do so. Investors are increasingly examining ethical issues when looking at mining.
Tailings, the waste material from extracting valuable minerals, are often held for decades behind dams that can be risky if they are poorly constructed, ill-maintained or filled with too much waste. Major failures of tailings dams have become more frequent as mining companies ramp up production to meet the world’s growing demand for commodities. Norilsk Nickel one of world’s most valuable miners with a market capitalization of roughly $43 billion, hasn’t publicly released details on its tailings dams. In 2016, heavy rainfall caused a Norilsk Nickel tailings dam in northern Russia to overflow, coloring a local river red. Miners of potash and phosphate—minerals used mainly in fertilizers—have been slow to disclose.
Another big company that has not released details is Canada-based Nutrient. Satellite images show two of the company’s six Saskatchewan mines are located a few miles from residential communities and one neighbors a bird-breeding area. A tailings pond at the company’s North Carolina phosphate mine is located next to the Pamlico River, which feeds into the state’s largest estuary.
In 2017, Israel Chemicals reported that the partial collapse of a subsidiary’s dike in Israel released 100,000 cubic meters of acidic wastewater that flowed into a nearby nature reserve. The wastewater resulted from the production of phosphate fertilizer.Vancouver-based Imperial Metals Corp.is tied to what is considered one of Canada’s worst environmental catastrophes. In 2014, a British Columbia dam owned by the company burst, sending some 25 million cubic meters of mining waste pouring into a pair of glacial lakes
Large Chinese miners such as Jiangxi Copper, Zijin Mining Group Co. and Zhongjin Gold Corp. also haven’t shared information with the investor coalition. There are 8,869 documented tailings dams, of which 16% are within about half a mile of a residential area, school or hospital, according to research led by the School of University of Science and Technology in Beijing. Karen Hudson-Edwards, a mining specialist at Britain’s University of Exeter, said the actual number in China is estimated at around 12,000 dams and there is little transparency on tailings risk in the country. There have been at least 12 serious tailings-dam accidents in China since the 1960s, with one in 2008 killing 277 people, according to the World Information Service on Energy, a Netherlands-based nonprofit.

The Triad National Security,*** the company in charge of Los Alamos National Laboratory’s (LANL) operations in 2018 lost track of 250 barrels of mixed hazardous waste on their way to the Waste Isolation Pilot Plant (WIPP) in Carlsbad. Mixed waste contains low-level radioactive waste and other hazardous materials. Failing to track such a high volume of waste is an egregious error that falls in line with the lab’s long history of serious missteps. “The fact that LANL has mischaracterized, misplaced, mis-inventoried — or whatever — 250 barrels of waste is pretty astounding,” said Jay Coghlan, executive director of Nuclear Watch New Mexico.
Still, Triad has committed less than a tenth of the violations that its predecessor, Los Alamos National Security LLC, used to average in a given year. A disastrous “kitty litter” incident happened under Los Alamos National Security, in which a waste barrel was packaged in error with a volatile blend of organic cat litter and nitrate salts, causing the container to burst and leak radiation at the Southern New Mexico storage site. WIPP closed for almost three years, and the cleanup cost about $2 billion.
***Triad is a public service oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), The Texas A&M University System (TAMUS), and The Regents of the University of California (UC).

Several members of the Tao Aboriginal community in Taiwan reiterated their decades-long demand that the government remove nuclear waste from Taitung County’s Orchid Island saying that they would not accept the NT$2.55 billion (US$83.57 million) in compensation. Since construction of a storage site was finished in 1982, more then 100,000 barrels of low-level radioactive waste have been transported from nuclear power plants on Taiwan proper to the outlying island, without obtaining residents’ consent in advance…. [According to the community], the government should establish a platform to discuss how to handle the nuclear waste and related compensation, while also continuing to reveal the storage site’s buried history,

Burkina Faso is struggling to contain a fast-growing jihadist insurgency. Along with Mali and Niger, it has become the main front line against terrorists in the Sahel, a dry strip of land that runs along the edge of the Sahara. This year alone the conflict has killed more than 1,600 people and forced half a million from their homes in Burkina Faso….A worrying new trend is a battle by jihadists and other armed groups to take control of the region’s gold rush.
Although gold has long been mined in the region…it has boomed in recent years with the discovery of shallow deposits that stretch from Sudan to Mauritania. International mining companies have invested as much as $5bn in west African production over the past decade, but the rush has also lured hundreds of thousands of unsophisticated “artisanal” miners. The International Crisis Group (ICG), an NGO, reckons that more than 2m people are involved in small-scale mining in Burkina Faso, Mali and Niger. In total they dig up 40-95 tonnes of gold a year, worth some $1.9bn-4.5bn.
This rush—in a region where states are already weak and unable to provide security—has sucked in a variety of armed groups and jihadists, including the likes of Ansar Dine and Islamic State in the Greater Sahara…The jihadists probably have direct control of fewer than ten mines…But they have influence over many more. In some areas artisanal miners are forced to pay “taxes” to the jihadists. In others, such as Burkina Faso’s Soum province, the miners hire jihadists to provide security… Other armed groups such as ethnic militias are also in on the bonanza and collect cash to guard mines. International mining firms may also be funding the jihadists by paying ransoms for abducted employees or “protection” money to keep mining, according to a study published by the OECD, a club of mostly rich countries.
For the moment much of Burkina Faso’s artisanal production is sneaked into Togo… Togo does not produce much gold domestically but it sent more than 12 tonnes of gold to Dubai in 2016. Gold is also taken out of the Sahel through major airports in hand luggage.

U.S. military researchers asked in 2019 two companies to develop new kinds of biological sensors that can detect underground disturbances or the presence of buried chemicals or weapons.
Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are looking to Raytheon BBN Technologies, and Signature Science, for the BioReporters for Subterranean Surveillance program. This project seeks to use indigenous and engineered organisms to sense changes of interest to military commanders in natural and built environments. Raytheon BBN and Signature Science won separate $1.6 million contracts for the Subterranean Surveillance progam.
The two companies will perform laboratory research and proof-of-concept demonstrations of biological sensing systems in well- controlled field tests that take advantage of recent advances in microbial science and synthetic biology to develop biological sensors, signal transducers, and reporters that can reveal subterranean phenomena at a distance. Bio Reporters should be able to sense a phenomenon at least one meter below the surface, propagate a signal to the surface within seven days, and be continuously detectable on the surface at a distance of 10 meters over the subsequent seven days.
DARPA researchers want Raytheon BBN and Signature Science experts to take advantage of the extensive biological networks that exist underground to monitor large areas to increase the military’s ability to detect subterranean events without the need for precise coordinates.

In more detail Signature Science and its partner, the Texas A&M University Center for Phage Technology, aim to leverage modern and synthetic phage biology and the straightforward molecular genetics of the harmless soil bacterium Bacillus subtilis to generate a new platform to recognize and report on specific chemical threats underground. The Spore-Phage Amplified Detection (SPADe) method, potentially extensible to explosives, radiation or physical disturbance sensing, seeks to substantially advance currently used techniques which rely heavily on manual soil testing.
From January 2020, the United Nations International Maritime Organization (IMO) will ban ships from using fuels with a sulphur content above 0.5%, compared with 3.5% now.The rules herald the biggest leap in how ships are powered since they switched from burning coal to oil over a century ago, but vessels will still be allowed to use higher-sulphur fuel if fitted with cleaning devices called scrubbers. Closed-loop scrubbers keep most of the water used for sulphur removal onboard for disposal at port. Open-loop systems, however, remove sulphur coming through a ship’s smokestack with water that can then be pumped overboard.
Years of studies have examined whether open-loop scrubbers introduce into waterways acidic sulphur harmful to marine life, cancer-causing hydrocarbons, nitrates leading to algal blooms and metals that impair organ function and cause birth defects. The results have largely been inconclusive and the IMO itself has encouraged further study into the environmental impact of scrubbers.
The stated aim of the new IMO measures is to improve human health.. A study in the journal Nature last year found ship emissions with current sulphur levels caused about 400,000 premature deaths from lung cancer and cardiovascular disease as well as around 14 million childhood asthma cases every year.
Singapore and Fujairah in the United Arab Emirates have banned the use of open-loop scrubbers from the start of next year. China is also set to extend a ban on scrubber discharge to more coastal regions.

A biological remediation pilot project seeking to enhance nature’s own ability to clear up oil spills in Iraq’s conflict-affected areas has been launched in Kirkuk, Iraq…This UNEP initiative seeks to harness naturally occurring soil bacteria as a powerful natural ally to decontaminate poisoned land. Over three years ago in summer 2016, the residents of Qayyarah—a small town of around 25,000 people, some 60 km south of Mosul—were caught in the line of fire as so-called Islamic State fighters torched nineteen nearby oil wells. So thick were the clouds of smoke, that people could not distinguish day from night for weeks in what infamously came to be known as the “Daesh winter”. Rivers of crude oil flowed through Qayyarah’s streets and into seasonal wadis as oil wells spewed tens of thousands of barrels of oil relentlessly for months. The specter of an even worse environmental catastrophe was heightened as the oil slick migrated to less than three kilometers from the Tigris River, Iraq’s water lifeline.
Following an epic battle to control the oil fires that took nearly a year, North Oil Company, which manages the oil fields of northern Iraq, is currently collecting an estimated 20,000 tonnes of remaining oil waste in Qayyarah into around a dozen large pits. Progress, however, has been slow and pools of heavy viscous oil remain on the doorsteps of entire neighborhoods and households, who complain about the impacts of noxious fumes on their children’s health.
“In some places, the layer of heavy oil is two to three meters thick, and long stretches of wadi channels are now effectively tarmac roads on which cars can be driven,” observed Mohammed Dawood, head of Qayarrah oil refinery’s environmental unit. Furthermore, Environment Ministry officials expressed concern that exceptionally heavy rains and flash floods of the 2018/19 winter season washed out oil from the holding pits into the Tigris River.
While oil production restarted in Qayyarah immediately after the conflict ended in June 2017, reaching currently an estimated 40,000 barrels per day, little has been done to clean up the conflict’s toxic aftermath… The UN Environment Programme in collaboration with the UN Assistance Mission in Iraq delivered a four-day hands-on training workshop on remediation of oil spills by the use of bacteria in September 2019. “By adding nutrients from manure, bulking agents like wood chips and water, we are simply creating the ideal conditions for bacteria to thrive and speeding up the natural process of breaking down the oil,”

The Louisiana University Marine Consortium (LUMCON) published in September 2019 a study on the Deepwater Horizon Oil Spill in Royal Society Open Science. The BP’s Deepwater Horizon oil rig exploded in April 2010, killing 11 workers. The subsequent cleanup and restoration had cost nearly $65 billion..but while while we can burn off and disperse oil on the surface, but we don’t have the technology to get rid of oil on the seafloor. So approximately 10 million gallons of it settled there….In 2017 , the The LUMCON surveyed the site surrounding the wreck of the rig, and another one 1,640 feet north. There were no giant isopods, glass sponges, or whip corals that would have jumped (metaphorically) at the chance to colonize the hard substrate of the rig, such as discarded sections of pipe…..But] crabs were just about everywhere. The researchers were shocked by the sheer number of crustaceans and other arthropods that had colonized the spill site. According to rough estimates, Atlantic deep sea red crabs, red shrimp, and white caridean shrimp were nearly eight times more populous at the Deepwater site than at other spots in the Gulf. “Everywhere there were crabs just kicking up black plumes of mud, laden with oil,” Nunnally says. But abundance does not mean the site was recovering, or even friendly to life. Particularly eerie was the crab’s achingly slow movement. “Normally, they scatter when they see the ROV lights,” he says. But these crabs seemed unbothered, or unaware of the robot’s presence.
The researchers hypothesize that degrading hydrocarbons are what’s luring unwitting crabs from the surrounding seafloor to the deep-sea equivalent of a toxic dump. “The chemical makeup of oil is similar to the oils naturally present on crustaceans,” Nunnally says. “They’re attracted to the oil site, but everything goes downhill for them once they’re in the area.” A similar kind of chemical confusion occurred at an oil spill in Buzzards Bay in New England in 2003, which attracted hordes of American lobsters. The researchers liken the death trap to the La Brea Tar Pits: Once lured in, the crabs lose their ability to leave. With no other species able to thrive in the area, the crabs have no food source—except each other. And as one might imagine, consuming the flesh of a toxin-riddled crab or starving to death in a deep-sea tar pit is sort of a lose/lose situation.
The crabs also looked anything but normal: some claws shrunken, some swollen, shriveled legs, a dusting of parasites. “There were deformities, but mostly things were missing,” Nunnally says. “You come in with eight legs and try to get away on four or five.” The researchers have yet to ascertain what specific toxins led to these maladies. The shrimp looked just as awful as the crabs. “They didn’t look like shrimp from other sites,” Nunnally says, adding that many of the small crustaceans had humps in their backs—tumors, perhaps.

Signs posted around the Grand Lake, Ohio read: “Danger: Avoid all contact with the water.” When dangerously high levels of toxins from blue-green algae in Grand Lake, Ohiio were publicized in 2009, many residents and tourists stopped using the 13,000-acre lake in northwest Ohio. Hotel revenue and home values sank for several years as algae bloomed in the state’s largest inland lake.
Greenish water still laps at Grand Lake’s shores, but recent water samples show that the amount of algae-feeding nutrients entering the lake is down significantly. State, federal and private donations covered more than $10 million in projects aimed at improving water quality. More people are boating on the lake again. Grand Lake could now serve as an example for communities with algae problems across the nation, experts say.
Algal blooms are on the rise, from Lake Erie to the Florida Everglades. In August 2019, the Environmental Protection Agency listed algae-related beach closures or health advisories in 23 states, and it said other blooms may not have been reported. In 2010, the EPA found that 20% of 50,000 lakes surveyed had been affected by phosphorous and nitrogen pollution, which feeds algae.e Cleaning up bodies of water choked with toxic algae has proved difficult. The project to repair Grand Lake, once one of the most polluted by algae in the nation, is one of the clearest successes. It shows cleanup is possible, but also expensive and time-consuming.
“It’s not restored yet, but it’s on the road to recovery,” said Stephen Jacquemin, an associate professor of biology at Wright State University-Lake Campus in Celina. Beginning in 2012, wetlands areas were built around the lake, which was hand dug in the 1830s. The thick stands of bulrushes and other plants have reduced phosphorous and nitrogen levels in water entering the wetlands before reaching the lake by as much as 90%, Dr. Jacquemin said. Three wetland areas, which cost a total of about $6 million to build, are constructed as a series of interconnected pools that allow particulates to settle out and plants and microbes to remove nutrients.
The state’s Department of Natural Resources has also dredged the lake bottom to remove nutrient-loaded sediment, and tried to clean up one of Grand Lake’s beaches near St. Marys by building a rock jetty and installing aerators and a curtain to filter water. Recent water tests there showed levels below 6 parts per billion of the toxin microcystin, under Ohio’s threshold of 20 parts per billion for avoiding contact with water.
As Green Algae Forces Beaches to Close, Ohio Lake Offers Hope, WSJ, Sept. 18, 2019
BBC has used satellite data to assess the severity of fires in Brazil, Indonesia, Siberia and Central Africa. It has concluded that although fires in 2019 have wrought significant damage to the environment, they have been worse in the past. More than 35,000 fires have been detected so far in 2019 in East Asia spreading smoky haze to Malaysia, Singapore, the south of Thailand and the Philippines, causing a significant deterioration in air quality. But this is substantially fewer than many other years including those, such as 2015, exacerbated by the El Nino effect which brought unusually dry weather.
In Indonesia, peatland is set alight by corporations and small-scale farmers to clear land for palm oil, pulp and paper plantations, and can spread into protected forested areas. The problem has accelerated in recent years as more land has been cleared for expanding plantations for the lucrative palm oil trade. Old palm trees on plantations that no longer bear fruit are often set on fire to be replaced by younger ones.
The number of recorded fires in Brazil rose significantly in 2019, but there were more in most years in the period 2002 to 2010. There is a similar pattern for other areas of Brazilian forestry that are not part of the Amazon basin. For 2019, we have data up to the end of August, and the overall area burnt for those eight months is 45,000 sq km. This has already surpassed all the area burnt in 2018, but appears unlikely to reach the peaks seen in the previous decade… “Fire signals an end of the deforestation process,” says Dr Michelle Kalamandeen, a tropical ecologist on the Amazon rainforest. “Those large giant rainforest trees that we often associate with the Amazon are chopped down, left to dry and then fire is used as a tool for clearing the land to prepare for pasture, crops or even illegal mining.”
The environmental campaign group Greenpeace has called the fires that have engulfed the Russian region of Siberia this year one of the worst outbreaks this century. The cloud of smoke generated was reported to have been the size of all the European Union countries combined. Forest fires in Siberia are common in the summer, but record-breaking temperatures and strong winds have made the situation particularly bad. Russia’s Federal Forestry Agency says more than 10 million hectares (100,000 sq km) have been affected since the start of 2019, already exceeding the total of 8.6 million for the whole of 2018…. Drawing on data for the number of fires, it is clear that there have been other bad years, notably in 2003.
Nasa satellites have identified thousands of fires in Angola, Zambia and DR Congo.However, these have not reached record levels. “I don’t think there’s any evidence that the fires we’re seeing in Africa are worse than we’ve seen in recent years,” Denis McClean, of the UN Disaster Risk Reduction agency, told the BBC. According to data analysed by Global Forest Watch, fires in DR Congo and Zambia are just above average for the season but have been higher in past years. In Angola, however, fires have been reported at close to record levels this year.
Some have drawn comparisons with the situation in the Amazon, but the fires in sub-Saharan Africa are different. Take DR Congo – most fires are being recorded in settled parts of the country’s southern, drier forest and savannah areas, and so far not in tropical rainforest. Experts say it is difficult to know what is causing these fires, which are seasonal. Many are likely to be on grassland, woodland or savannah in poor farming communities. “Fires are very important landscape management tools and are used to clear land for planting crops,” says Lauren Williams, a specialist in Central and West African forests at the World Resources Institute.

China is betting that CRISP technology*can transform the country’s food supply. China also expanded its efforts beyond its borders in 2017, when the state-owned company ChemChina bought Switzerland-based Syngenta—one of the world’s four largest agribusinesses, which has a large R&D team working with CRISPR—for $43 billion. That was the most China has ever spent on acquiring a foreign company, and it created an intimate relationship between government, industry, and academia—a “sort of a ménage à trois” that ultimately could funnel intellectual property from university labs into the company, says plant geneticist Zachary Lippman of Cold Spring Harbor Laboratory in New York.
Chinese leaders “want to strategically invest in genome editing, and [by that] I mean, catch up,” says Zhang Bei, who heads a team of 50 scientists at the Syngenta Beijing Innovation Center…China may one day need CRISPR-modified plants to provide enough food for its massive population…. China needs to resolve how it will regulate CRISPR-engineered crops—a divisive issue in many countries. In a 2018 decision that rocked big agriculture, a European court ruled that such crops are genetically modified organisms (GMOs) that need strict regulation. In contrast, the U.S. Department of Agriculture (USDA) exempts genome-edited plants from regulations covering GMOs as long as they were produced not by transferring DNA from other species, but by inducing mutations that could have occurred naturally or through conventional breeding. Chinese consumers are wary of GM food. The country strictly limits the import of GM crops, and the only GM food it grows are papayas for domestic consumption. But for CRISPR, many plant researchers around assume China will follow in the United States’s footsteps…
For Corteva,Syngenta, and the other two big ag companies—BASF and Bayer (which acquired Monsanto last year)—the long game is to use CRISPR to develop better versions of their serious moneymakers, the “elite” varieties of a wide range of crops that have big commercial markets. They sell dozens of kinds of elite corn seeds—for example, inbred strains that consistently have high yields or reliable resistance to herbicides. Creating the genetic purity needed for an elite variety typically takes traditional breeding of many generations of plants, and CRISPR is seen as the cleanest way to improve them quickly. The earlier methods of engineering a plant can lead to unwanted genomic changes that must be laboriously culled…
Syngenta sees CRISPR-modified corn as a big opportunity in China, which grows more hectares of corn than any other crop. Yields per hectare are only 60% of those in the United States because corn ear worms often weaken Chinese crops. A fungus thrives in the weakened plants, producing a toxin that makes the resultant ears unfit for animal feed. As a result, China must import a great deal of corn. (According to USDA, 82% of U.S.-grown corn has been engineered to have a bacterial gene that makes it resistant to ear worms.)…“Syngenta is putting a lot of emphasis to grow in China to become the leading seed company. The China market as a whole, if it modernizes as the U.S. has modernized, can be as big as the U.S. market.”

* Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. Several approaches to genome editing have been developed. A recent one is known as CRISPR-Cas9.
Small modular nuclear reactors (SMRs) are relatively small and flexible: they have a power capacity of up to 300 MW(e) and their output can fluctuate in line with demand. This makes them particularly attractive for remote regions with less developed grids, but also for use as a complement to renewables and for non-electric applications of nuclear power. SMRs can be manufactured and then shipped and installed on site, so they are expected to be more affordable to build.
Globally, there are about 50 SMR designs and concepts at different stages of development. Three SMR plants are in advanced stages of construction or commissioning in Argentina, China and Russia, which are all scheduled to start operation between 2019 and 2022…Some SMR designs have features that could reduce the tasks associated with spent fuel management. Power plants based on these designs require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants, and some are even designed to operate for up to 30 years without refuelling. Nevertheless, even in such cases, there will be some spent fuel left, which will have to be properly managed.

Increasingly sophisticated technology that detects nuances in sound inaudible to humans is capturing clues about people’s likely locations, medical conditions and even physical features.Law-enforcement agencies are turning to those clues from the human voice to help sketch the faces of suspects. Banks are using them to catch scammers trying to imitate their customers on the phone, and doctors are using such data to detect the onset of dementia or depression. That has… raised fresh privacy concerns, as consumers’ biometric data is harnessed in novel ways.
“People have known that voice carries information for centuries,” said Rita Singh, a voice and machine-learning researcher at Carnegie Mellon University who receives funding from the Department of Homeland Security…Ms. Singh measures dozens of voice-quality features—such as raspiness or tremor—that relate to the inside of a person’s vocal tract and how an individual voice is produced. She detects so-called microvolumes of air that help create the sound waves that make up the human voice. The way they resonate in the vocal tract, along with other voice characteristics, provides clues on a person’s skull structure, height, weight and physical surroundings, she said.
Nuance’s voice-biometric and recognition software is designed to detect the gender, age and linguistic background of callers and whether a voice is synthetic or recorded. It helped one bank determine that a single person was responsible for tens of millions of dollars of theft, or 18% of the fraud the firm encountered in a year, said Brett Beranek, general manager of Nuance’s security and biometrics business.
Audio data from customer-service calls is also combined with information on how consumers typically interact with mobile apps and devices, said Howard Edelstein, chairman of behavioral biometric company Biocatch. The company can detect the cadence and pressure of swipes and taps on a smartphone. How a person holds a smartphone gives clues about their age, for example, allowing a financial firm to compare the age of the normal account user to the age of the caller…
If such data collected by a company were improperly sold or hacked, some fear recovering from identity theft could be even harder because physical features are innate and irreplaceable.

In August 2019, Tepco projected that storage of radioactive water at the Fukushima nuclear plant would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate. According to Tepco, the Fukushima No. 1 plant had 960 massive tanks containing 1.15 million tons of treated water as of July 18, 2019. Water that has touched the highly radioactive melted fuel debris has been cleaned up through water treatment machines and is stored in the tanks, but the high-tech treatment machines are able to remove most radionuclides except tritium. The plant currently sees an increase of contaminated water by 170 tons a day, Tepco says.
Releasing tritium-tainted water into the sea in a controlled manner is common practice at nuclear power plants around the world, and it was generally considered the most viable option as it could be done quickly and would cost the least. The head of the Nuclear Regulation Authority, Toyoshi Fuketa, has long said that releasing the treated water into the sea is the most reasonable option, but people in Fukushima, especially fishermen, fear it will damage the region’s reputation.
Addressing those concerns, the government panel, launched in November 2016, has been looking for the best option in terms of guarding against reputational damage. Injecting it into the ground, discharging it as steam or hydrogen, or solidification followed by underground burial have all been on the table. Under the current plan, Tepco is set to increase the tank space to store 1.37 million tons of water a total, but estimates show that will only last until summer 2022. But the more space it creates, the bigger the decommissioning headache becomes.

The world’s largest rainforest and a crucial store of carbon dioxide gets most of its phosphorous, an important nutrient, from an unexpected source: fires in Africa. Strange as it may seem, we thought that the Amazon got much of its phosphorus from dust whipped up from the Sahara Desert and transported across the Atlantic on the wind.
Cassandra Gaston at the University of Miami, US, and her colleagues had set out to quantify the effect of the phosphorous in Saharan dust on the Amazon’s growth. To do this, they collected and analysed particles caught in filters from a hilltop in French Guiana, at the northern edge of the Amazon Basin. But at the same time, they used satellites to track smoke from fires in Africa — both people burning wood and natural forest fires — drifting Westwards across the ocean. It turned out that the arrival of patches of smoke coincided with high levels of phosphorous being detected in the filters. Gaston and her team then estimated how much of the phosphorus deposited on the Amazon Basin comes from African biomass burning. They found that, in Spring, smoke from the fires was responsible for most of the nutrient entering the Amazon Basin. …The findings suggest that people burning wood and other materials in Africa might have an impact on how much the Amazon grows and therefore how much carbon it stores in future.

Cigarette butts, the most littered items in the world, are posing an intractable trash problem for regulators and tobacco companies: Throwing them on the ground is a firmly entrenched habit for many smokers. Regulators are taking a tougher stance on cigarette filter pollution amid concerns about the environmental impact of single-use plastic. Butts for decades have been made from cellulose acetate, a form of plastic, which takes years to break down. Studies show that butts—which often wash from sidewalks into drains and then waterways—can be toxic to fish.
About 65% of cigarettes smoked in the U.S. are littered, according to Keep America Beautiful, a nonprofit whose cigarette litter prevention program is funded by the tobacco industry. “That whole habit is so ingrained it becomes part of the ritual of taking the cigarette out of the pack, lighting it, smoking it, putting it on the ground,” said Christopher Proctor, chief scientific officer at British American Tobacco (BAT), whose cigarette brands include Kent, Newport and Camel. “Changing ingrained behavior is a really difficult thing to do.”
The European Union in May adopted new rules under which members must pass laws within two years requiring tobacco companies to fund the cleanup of filter litter as part of a broader crackdown on single-use plastics. A bill proposing banning filters has made its way through the California Senate and will be heard by the lower house next year. In response, BAT and Japan Tobacco Inc. are testing biodegradable filters, while Philip Morris International Inc. is assessing the appetite for portable ashtrays. Companies also are tapping behavioral psychologists to understand what propels smokers to litter, hoping to forestall stricter regulation…
he World Health Organization says that when filters do break down they leach out some of the 7,000 chemicals contained in cigarettes, many of which are environmentally toxic.

In July 2019, a combination of the nuclear sterile insect technique (SIT) with the incompatible insect technique (IIT) has led to the successful suppression of mosquito populations, a promising step in the control of mosquitoes that carry dengue, the Zika virus and many other devastating diseases. The results of the recent pilot trial in Guangzhou, China, carried out with the support of the IAEA in cooperation with the Food and Agriculture Organization of the United Nations (FAO), were published in Nature on 17 July 2019.
SIT is an environmentally-friendly insect pest control method involving the mass-rearing and sterilization of a target pest using radiation, followed by the systematic area-wide release of sterile males by air over defined areas. The sterile males mate with wild females, resulting in no offspring and a declining pest population over time. IIT involves exposing the mosquitoes to the Wolbachia bacteria. The bacteria partially sterilizes the mosquitoes, which means less radiation is needed for complete sterilization. This in turn better preserves the sterilized males’ competitiveness for mating.
The main obstacle in scaling up the use of SIT against various species of mosquitoes has been overcoming several technical challenges with producing and releasing enough sterile males to overwhelm the wild population.
For example, the researchers used racks to rear over 500 000 mosquitoes per week that were constructed based on models developed at the Joint FAO/IAEA Division’s laboratories near Vienna, Austria. A specialized irradiator for treating batches of 150 000 mosquito pupae was also developed and validated with close collaboration between the Joint FAO/IAEA Division and the researchers…The results of this pilot trial, using SIT in combination with the IIT, demonstrate the successful near-elimination of field populations of the world’s most invasive mosquito species, Aedes albopictus (Asian tiger mosquito). The two-year trial (2016-2017) covered a 32.5-hectare area on two relatively isolated islands in the Pearl River in Guangzhou. It involved the release of about 200 million irradiated mass-reared adult male mosquitoes exposed to Wolbachia bacteria…
Experts in China plan to test the technology in larger urban areas in the near future using sterile male mosquitoes from a mass-rearing facility in Guangzhou, said Zhiyong Xi, Director of Sun Yat-sen University-Michigan State University’s Joint Center of Vector Control for Tropical Diseases and Professor at Michigan State University in the United States

Agitations against the Kudankulam nuclear plant broke out in June 2019. Villages around the contentious reactors moved a resolution to put a stop to the government’s plans to construct an Away From Reactor (AFR) facility on the premises of the nuclear power plant. The AFR is a storage unit meant to store spent fuel generated at the two nuclear plants in Kudankulam… While resolutions passed at four villages – Kavalkinar, Vadakankulam, Perumanal and Kudankulam were recorded by district authorities, a similar move in the village of Vijayapathi was stopped. The decision led to protests in the village and was forcefully dispersed by the police. …
A public hearing regarding the AFR scheduled for July 10, 2019 was recently postponed indefinitely. A look at the circular shows that only two villages were invited – Kudankulam and Vijayapathi. Activists allege that this was an intentional attempt to shut down dissent against the proposed facility.
The resolutions included – opposition to collection of nuclear waste in Kudankulam, demand to stop construction of an AFR facility and demand to permanently shut down the plant. Opposition parties and activists had urged the Centre to come out with a detailed plan for setting up a permanent deep geological repository and drop the plan of a proposed Away From Reactor facility. “This entire exercise is meant to create storage for spent fuel and an AFR is only a temporary solution till the government finds land to build a deep geological repository,” explains Sundarrajan. “But across the country, no state is ready to risk giving land for permanent disposal of nuclear waste. So, residents fear that this will used as an excuse by the government to make the AFR a permanent storage space.”

In July 2019, the US House of Representatives added an unusual amendment to the 2020 U.S. defense budget: a requirement that the Department of Defense reveal details of any biological warfare research it did involving ticks during the Cold War. The requirement stems from allegations that Lyme disease was actually a biowarfare experiment accidentally released into the wild. The amendment was added to the defense budget by New Jersey Congressman Christopher Smith. It calls on the U.S. government to “conduct a review of whether the Department of Defense experimented with ticks and other insects regarding use as a biological weapon between the years of 1950 and 1975.”
If there was any sort of research the Pentagon Inspector General “must provide the House and Senate Armed Services committees with a report on the experiments’ scope and ‘whether any ticks or insects used in such experiments were released outside of any laboratory by accident or experiment design.’”
The call for information comes after the publication of the book Bitten: The Secret History of Lyme Disease and Biological Weapons. A major allegation in the book is that Willy Burgdorfer, the discoverer of the bacterium that causes Lyme Disease, claimed that the disease was the result of a biological weapons program that went awry. Burgdorfer himself was involved in biological warfare programs that involved using blood-sucking insects, including fleas, ticks, and mosquitoes, as vectors for the transmission of human diseases.
Weaponizing bugs isn’t a completely novel idea. Imperial Japan weaponized insects, typically fleas infected with plague and cholera, where they were used against the civilian population in China. The Japanese military organization responsible for the research, Unit 731, was later rounded up by the U.S. military after the war. Despite committing serious, egregious crimes against humanity, including vivisection, members of the unit were only lightly punished by the Allies, reportedly in exchange for research data.
Lyme Disease affects approximately 30,000 people a year, primarily in the northeastern United States. The book alleges biowarfare research involving ticks took place at Fort Detrick, Maryland, and Plum Island, New York—both areas where CDC maps note the disease is very prevalent, but the CDC itself does not have an opinion on the allegation.

The southern city of Chennai—India’s fifth largest with a population of around 10 million—has been meeting only two-thirds of its water needs for weeks, the product of years of drought and decades of failure to manage the region’s water resources. Residents have been scrambling around the clock to get water—spending hours chasing government tankers or paying private companies to deliver water. Recent light rains broke a 200-day streak without rain. But the first month of India’s annual monsoon brought one-third less rain than the 50-year average, the driest June in five years, according to the India Meteorological Department.
The acute water shortage in one of India’s largest cities has been building for decades through a mix of population growth, poor planning and increasingly erratic monsoon rains….
The situation in Chennai reflects a larger water crisis spreading across India. Half the country’s population—600 million people—live in areas where water resources are highly or extremely stressed. About 100 million people living in 21 of India’s biggest cities may see their groundwater exhausted by the end of next year, according to a 2018 study by NITI Aayog, an Indian government policy think tank. By 2030, demand for water will be double the country’s supply, the report said. And the impact will go far beyond the areas actually affected by water shortages: Almost one-third of the country’s agricultural output comes from areas most affected by water shortages…
The scarcity has led to clashes between neighbors. “No one is ready to share even a glass of water,” she said.

According to DARPA, terrorist attacks involving the use of proliferated radiological and special nuclear materials pose a potential threat to U.S. citizens and servicemembers. Early detection of such materials and devices made from them is a critical part of the U.S. strategy to prevent attacks. Lower-cost and more sensitive detectors, along with innovative deployment strategies, could significantly enhance detection and deterrence of attack.
The SIGMA program aims to revolutionize detection and deterrent capabilities for countering nuclear terrorism. A key component of SIGMA thus involves developing novel approaches to achieve low-cost, high-efficiency, packaged radiation detectors with spectroscopic gamma and neutron sensing capability. The program will seek to leverage existing infrastructure to help enable these next-generation detectors and their deployment in order to demonstrate game-changing detection and deterrent systems.
The Defense Advanced Research Projects Agency fielded a sensor network to trace radioactive and nuclear materials during the Indianapolis 500 event on June 30, 2019
The daily plastic waste generated by the average Indian—while much lower than the average American—climbed 69% between 2015 and 2018, according to government estimates. Across the country, dumps are overflowing and drains are clogging with plastic, while cows—considered sacred—are getting sick after eating packaging….To get a grip, India has instituted some of the world’s strictest rules on single-use plastic, forcing companies to collect packaging that is often left as litter.
Nonrecyclable packaging is a problem globally, but particularly acute in countries with poor waste management. Many Indian households lack regular collection services so they burn trash or dump it on the side of the road. Much of the waste ends up in waterways. Of plastic found in the world’s oceans, 90% is traced to 10 rivers, according to a 2017 study published in the journal Environmental Science & Technology. Eight of the rivers are in Asia and two flow through India.
In emerging markets, products like shampoo and detergent are often sold in single-serve pouches similar to the ketchup packets that come with an order of fries. The resilient “multilayer” pouches protect against extreme temperatures and contamination, and, most important, are affordable for poor consumers. Single-serve packets make up over 80% of shampoo sales in India, Indonesia and the Philippines, according to Euromonitor….This type of packaging combines different types of plastic with materials like aluminum. That makes it nonrecyclable and of no interest to India’s waste pickers who trawl through trash looking for recyclables to sell. Three years ago, India’s government said it would ban multilayer packaging by 2018, setting off alarm bells through the industry…
A consortium—including Nestlé, Pepsi and Mentos-maker Perfetti Van Melle SpA—tried for months to develop a recyclable alternative. After little success, they decided on a different approach. Through street plays and workshops, the companies trained 1,500 waste pickers across eight cities to identify and collect multilayer packaging, paying them for what they brought in. The pilot program amassed 680 metric tons of material in three months. In March 2018, New Delhi changed the law to allow the sale of multilayer packaging. The caveat is that companies must collect back the equivalent volume of what they sell and find other uses for it, like sending it to cement plants as fuel…
Despite such efforts, some government officials have accused companies of moving too slowly. E. Ravendiran of the Maharashtra Pollution Control Board says companies only swung into action after being threatened with bans or having to pay a deposit on multilayer packaging sold. Executives say the target of collecting 100% of multilayer plastic by 2020 is unrealistic and that details on how the rule will be implemented are scarce.
Hassan, a former waste picker who manages a small team of waste collectors in Bangalore, says pickers aren’t financially motivated to bend down hundreds of times to collect a kilogram of multilayer plastic from piles of mixed waste or just off the street. Saahas pays him 27 rupees (around 39 U.S. cents) for one kilogram of plastic bottles, compared with just 4 rupees for one kilogram of multilayer packaging, which is much harder to collect.

Breakthroughs in the science of programmable gene expression inspired DARPA to establish the PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program with the goal of delivering powerful new defenses against public health and national security threats. DARPA has now selected five teams to develop a range of new medical interventions that temporarily and reversibly modulate the expression of protective genes to guard against acute threats from influenza and ionizing radiation, which could be encountered naturally, occupationally, or through a national security event.
The program builds from the understanding that the human body has innate defenses against many types of health threats, but that the body does not always activate these defenses quickly or robustly enough to block the worst damage. To augment existing physiological responses, PREPARE technologies would provide a programmable capability to up- or down-regulate gene expression on demand, providing timely, scalable defenses that are proportional to anticipated threats. Service members and first responders could administer these interventions prior to threat exposure or therapeutically after exposure to mitigate the risk of harm or death.
Influenza: “Researchers working within the PREPARE program seek to improve rates of survival and recovery in catastrophic scenarios for which reliable and scalable countermeasures don’t currently exist,” said Dr. Renee Wegrzyn, the PREPARE program manager….Three PREPARE teams are pursuing multi-pronged approaches to influenza defense and treatment that use programmable gene modulators to boost the human body’s natural defenses against influenza and also weaken the virus’ ability to cause harm by directly neutralizing the viral genomes. If successful, their approaches would potentially protect against virtually all influenza strains — regardless of whether a virus is newly emergent or has developed drug resistance — and would provide near instantaneous immunity, in contrast to traditional vaccines. Additionally, the teams are designing their countermeasures so that they are simple to deliver — for example, as intranasal sprays — reducing the logistical challenge of protecting large numbers of people.A team led by DNARx LLC, under principal investigator Dr. Robert Debs, aims to develop a new DNA-encoded gene therapy that helps patients fight influenzaby boosting the natural immune response and other protective functions of their nasal passages and lungs.
Ionizing Gamma Radiation: Other PREPARE teams are pursuing treatments to protect the body from the effects of ionizing gamma radiation. In humans, radiation poisoning primarily affects stem cells in the blood and gut, yet existing treatments only help to regenerate blood cells, and only with limited effect. There is no possibility for prophylactic administration of these drugs, and most must be delivered immediately following radiation exposure to provide any benefit. There are no existing medical countermeasures for radiation damage to the gut… A team led by the University of California, San Francisco, under principal investigator Dr. Jonathan Weissman, also aims to develop gene therapies to enhance resilience against ionizing radiation. The team’s approach should result in an intravenous or orally available treatment that activates innate defenses in gut and blood stem cells for a period of several weeks.

In the 1980s, the village of Soumousso in Burkina Faso helped launch one of the most powerful weapons against malaria: insecticide-treated bed nets, which had early field trials there and went on to save millions of lives. But as mosquitoes developed resistance to widely used insecticides, the nets lost some of their power. Now, researchers are hoping the village can help make history again by testing a new countermeasure: a genetically modified (GM) fungus that kills malaria-carrying mosquitoes. In tests in a 600-square-meter structure in Soumousso called the MosquitoSphere—built like greenhouse but with mosquito netting instead of glass—the fungus eliminated 99% of the mosquitoes within a month, scientists report in the magazine Science.
The fungus also has clear advantages, however: It spares insects other than mosquitoes, and because it doesn’t survive long in sunlight, it’s unlikely to spread outside the building interiors where it would be applied. Fungi naturally infect a variety of insects, consuming the host’s tissues in order to reproduce, and they have been used for decades to control a wide variety of crop pests….Researchers have tested dozens of different fungal strains against disease-carrying mosquitoes, but none was effective enough to pass muster. So researchers from the University of Maryland (UMD) in College Park and the Research Institute of Health Sciences & Centre Muraz in Bobo-Dioulasso, Burkina Faso, endowed a strain called M. pingshaense with a gene for a toxin isolated from spider venom that turns on when it contacts hemolymph, the insect version of blood. In the lab, the team showed its creation could kill mosquitoes faster and that just one or two spores could cause a lethal infection.
Burkina Faso was a promising place for a field test: Unlike many countries in Africa, it has an established system to evaluate and approve the use of GM organisms. It also has one of the highest rates of malaria in the world, and insecticide-resistant mosquitoes are widespread. For those and other reasons, the U.S. National Institutes of Health funded the MosquitoSphere, which is specifically designed to test GM organisms.

CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon (CFC) chemicals that were initially developed as refrigerants during the 1930s. However, it took many decades for scientists to discover that when CFCs break down in the atmosphere, they release chlorine atoms that are able to rapidly destroy the ozone layer which protects us from ultraviolet light. A gaping hole in the ozone layer over Antarctica was discovered in the mid 1980s. The international community agreed the Montreal Protocol in 1987, which banned most of the offending chemicals. Recent research suggests that the hole in the Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.
CFC-11 was the second most abundant CFCs and was initially seen to be declining as expected.However in 2018 a team of researchers monitoring the atmosphere found that the rate of decline had slowed by about 50% after 2012. Further detective work in China by the Environmental Investigation Agency in 2018 seemed to indicate that the country was indeed the source. They found that the illegal chemical was used in the majority of the polyurethane insulation produced by firms they contacted.One seller of CFC-11 estimated that 70% of China’s domestic sales used the illegal gas. The reason was quite simple – CFC-11 is better quality and much cheaper than the alternatives.
This new paper seems to confirm beyond any reasonable doubt that some 40-60% of the increase in emissions is coming from provinces in eastern China. Using what are termed “top-down” measurements from air monitoring stations in South Korea and Japan, the researchers were able to show that since 2012 CFC-11 has increased from production sites in eastern China.They calculated that there was a 110% rise in emissions from these parts of China for the years 2014-2017 compared to the period between 2008-2012.
“If we look at these extra emissions that we’ve identified from eastern China, it equates to about 35 million tonnes of CO2 being emitted into the atmosphere every year, that’s equivalent to about 10% of UK emissions, or similar to the whole of London.” The Chinese say they have already started to clamp down on production by what they term “rogue manufacturers”. In November 2018, several suspects were arrested in Henan province, in possession of 30 tonnes of CFC-11.

The Mobil Foundation sought to use its tax-exempt grants to shape American laws and regulations on issues ranging from the climate crisis to toxic chemicals – with the explicit goal of benefiting Mobil, documents obtained by the Guardian newspaper show. Recipients of Mobil Foundation grants included Ivy League universities, branches of the National Academies and well-known civic organizations and environmental researchers. Benefits for Mobil included – in the foundation’s words – funding “a counterpoint to so-called ‘public interest’ groups”, helping Mobil obtain “early access” to scientific research, and offering the oil giant’s executives a forum to “challenge the US Environmental Protection Agency (EPA) behind-the-scenes”….
A third page reveals Mobil Foundation’s efforts to expand its audience inside environmental circles via a grant for the Environmental Law Institute, a half-century-old organization offering environmental law research and education to lawyers and judges. “Institute publications are widely read in the environmental community and are helpful in communicating industry’s concerns to such organizations,” the entry says. “Mobil Foundation grants will enhance environmental organizations’ views of Mobil, enable us to reach through ELI activities many groups that we do not communicate with, and enable Mobil to participate in their dialogue groups.”
The documents also show Mobil Foundation closely examining the work of individual researchers at dozens of colleges and universities as they made their funding decisions, listing ways that foundation grants would help shape research interests to benefit Mobil, help the company recruit future employees, or help combat environmental and safety regulations that Mobil considered costly. “It should be a wake-up call for university leaders, because what it says is that fossil fuel funding is not free,” said Geoffrey Supran, a postdoctoral researcher at Harvard and MIT. “When you take it, you pay with your university’s social license,” Supran said. “You pay by helping facilitate these companies’ political and public relations tactics.”
In some cases, the foundation described how volunteer-staffed not-for-profits had saved Mobil money by doing work that would have otherwise been performed by Mobil’s paid staff, like cleaning birds coated in oil following a Mobil spill. In 1987, the International Bird Rescue Research Center’s “rapid response and assistance to Mobil’s West Coast pipeline at a spill in Lebec, CA not only defused a potential public relations problem”, Mobil Foundation said, “but saved substantial costs by not requiring our department to fly cross country to respond”.d of trustees at the Woods Hole Oceanographic Institution (recipient of listed donations totalling over $200,000 from Mobil) and a part of UN efforts to study climate change.
Wise ultimately co-authored two UN Intergovernmental Panel on Climate Change reports, serving as a lead author on one. One report chapter Wise co-authored prominently recommended, among other things, burning natural gas (an ExxonMobil product) instead of coal as a way to combat climate change.

The instinctive response of many environmentalists is to to fence off protected areas as rapidly and extensively as possible. That thought certainly dominates discussions of the Convention on Biological Diversity, the main relevant international treaty. An eight-year-old addendum to the pact calls for 17% of the world’s land surface and 10% of the ocean’s water column (that is, the water under 10% of the ocean’s surface) to be protected by 2020. Currently, those figures are 15% and 6%. Campaigners want the next set of targets, now under discussion, to aim for 30% by 2030—and even 50% by 2050. This last goal, biogeographers estimate, would preserve 85% of life’s richness in the long run. As rallying cries go, “Nature needs half” has a ring to it, but not one that sounds so tuneful in the poor countries where much of the rhetorically required half will have to be found. Many people in such places already feel “Cornered by Protected Areas.” (See also Biodiversity and Human Rights)
James Watson, chief scientist at the Wildlife Conservation Society (wcs), another American charity, has an additional worry about focusing on the fence-it-off approach. If you care about the presence of species rather than the absence of humans, he warns, “‘nature needs half’ could be a catastrophe—if you get the wrong half.” Many terrestrial protected areas are places that are mountainous or desert or both. Expanding them may not translate into saving more species. Moreover, in 2009 Lucas Joppa and Alexander Pfaff, both then at Duke University in North Carolina, showed that protected areas disproportionately occupy land that could well be fine even had it been left unprotected: agriculture-unfriendly slopes, areas remote from transport links or human settlements, and so on. Cordoning off more such places may have little practical effect.
In the United States it is the underprotected southern Appalachians, in the south-east of the country, that harbour the main biodiversity hotspots. The largest patches of ring-fenced wilderness, however, sit in the spectacular but barren mountain ranges of the west and north-west. In Brazil, the world’s most speciose country, the principal hotspots are not, as might naively be assumed, in the vast expanse of the Amazon basin, but rather in the few remaining patches of Atlantic rainforest that hug the south-eastern coast.
Nor is speciosity the only consideration. So is risk-spreading. A team from the University of Queensland, in Australia, led by Ove Hoegh-Guldberg, has used a piece of financial mathematics called modern portfolio theory to select 50 coral reefs around the world as suitable, collectively, for preservation. Just as asset managers pick uncorrelated stocks and bonds in order to spread risk, Dr Hoegh-Guldberg and his colleagues picked reefs that have different exposures to rising water temperatures, wave damage from cyclones and so on. The resulting portfolio includes reefs in northern Sumatra and the southern Red Sea that have not previously registered on conservationists’ radar screens…
Another common finding—counterintuitive to those who take the “fence-it-all-off” approach—is that a mixed economy of conservation and exploitation can work. For example, rates of deforestation in a partly protected region of Peru, the Alto Mayo, declined by 78% between 2011 and 2017, even as coffee production increased from 20 tonnes a year to 500 tonnes.
Environmental groups can also draw on a growing body of academic research into the effective stewardship of particular species. For too long, says William Sutherland, of Cambridge University, conservationists have relied on gut feelings. Fed up with his fellow practitioners’ confident but unsubstantiated claims about their methods, and inspired by the idea of “evidence-based medicine”, he launched, in 2004, an online repository of relevant peer-reviewed literature called Conservation Evidence. Today this repository contains more than 5,400 summaries of documented interventions. These are rated for effectiveness, certainty and harms. Want to conserve bird life threatened by farming, for example? The repository lists 27 interventions, ranging from leaving a mixture of seed for wild birds to peck (highly beneficial, based on 41 studies of various species in different countries) to marking bird nests during harvest (likely to be harmful or ineffective, based on a single study of lapwing in the Netherlands). The book version of their compendium, “What Works in Conservation”, runs to 662 pages. It has been downloaded 35,000 times.

How do you make a 10,000-tonne container ship disappear? At Alang, a small town in Gujarat, on the western coast of India is the world’s biggest ship-breaking town. Almost a third of all retired vessels—at least 200 each year—are sent to be broken up here, at over 100 different yards stretching along 10km of sand. The industry employs some 20,000 people, almost all men who migrate from the poorer states of India’s northern Hindi-speaking belt. Taxes paid by breakers generate huge sums for the state government. Yet it is a dangerous industry for its workers and a filthy one in environmental terms.
Of 744 ships that were pulled apart worldwide last year, 518 were dismantled on beaches. Only 226 were processed “off the beach” at industrial sites designed for the purpose, according to the Shipbreaking Platform, an ngo which campaigns against beach-breaking. The majority of big shipping firms use beaches, except a tiny few such as Hapag Lloyd of Germany and Boskalis of the Netherlands.
A typical operation involves a ship being beached at low tide. Once her fittings and other resaleable parts are removed, hundreds of workers with gas blowtorches clamber over the vessel’s hull, cutting it into huge steel blocks. These are then dropped onto the beach, where they are cut up again before being sold, then rerolled for use in construction.
Apart from the danger of dropping tens of tonnes of steel from a great height, the method is immensely polluting. A review in 2015 by Litehauz, a Danish marine environmental consultancy, found that in the process of scrapping a 10,000-tonne ship at least 120 tonnes of steel becomes molten and is lost in the sea. Levels of mercury and lead, as well as oil, in Alang’s water are at least 100 times higher than at other beaches. Workers must handle asbestos and dangerous chemicals. Accidents are common. Last year 14 workers died at Alang.Alang is just one of many ship-breaking centres in South Asia. Among the others are beaches in Bangladesh (where workers reportedly include children) and Pakistan. Last year the subcontinent recycled around 90% of the world’s ships by tonnage.
Ship-breaking is concentrated in the region for three reasons. Prices for scrap steel are higher than elsewhere (90% of a ship is typically steel), thanks to demand for rerolled steel for construction. Labour costs are lower than at yards in Europe, America or Turkey (workers at Alang make up to 800 rupees, or $11, per day, and usually less) and safety and environmental regulations are much weaker. Most sellers scrap their ships in South Asia because they get better prices for them.
Shipowners, in particular Maersk, a Danish company which is the world’s biggest shipper, are preparing to comply with them…At the Baijnath Melaram shipyard a huge crane barge sits in the water next to a stretch of “impermeable” concrete. “We used to have to winch the blocks up the beach,” says Siddharth Jain, the firm’s business manager. Now, the crane lifts blocks of steel down from the ships directly to the concrete, so that they need never touch the sand. In contrast to the yards nearby, where men in simple work clothes and no safety goggles operate blowtorches, the workers scuttling around Baijnath Melaram wear boiler suits, face masks and helmets.
The changes are largely down to Maersk… Around 70 more are upgrading in order to meet standards set by the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, an unratified treaty on ship recycling. Maersk’s campaign is in response to new regulations in force since December 31st 2018 that require all European-flagged vessels to be recycled at shipyards approved by Brussels. Just over a third of the world’s ships fall in this category. Maersk, whose fleet is roughly 40% European-flagged, hopes that the best yards at Alang will be able to comply with the new rules. Two Indian yards have already been audited for the European certification; 11 more have applied. “If we sustain that momentum, in five, six or seven years all of Alang could be really responsible,” says John Kornerup Bang, Maersk’s sustainability chief.
But on January 30, 2019 the eu announced that the Indian yards audited will not make the list,… Ingvild Jenssen of the Shipbreaking Platform says that even Alang’s best yards are not clean enough. She argues that Maersk’s efforts merely “greenwash” a model that needs to change completely…. Not clean enough for Europe; but too expensive to compete with breakers in Bangladesh or Pakistan which have not changed at all. If that happens, the industry in Alang—and the jobs and revenue it generates—could disappear almost as quickly as the ships it dismantles.
Excerpt from HIgh by the Beach: Ship Recycling, Economist, Mar. 9, 2019
The hard surface of waterborne plastic provides an ideal environment for the formation of biofilm by opportunistic microbial colonisers, and could facilitate a novel means of dispersal for microorganisms across coastal and marine environments. Biofilms that colonise the so-called ‘plastisphere’ could also be a reservoir for faecal indicator organisms (FIOs), such as Escherichia coli, or pathogenic bacteria such as species of Vibrio.
A study published in March 2019 looks into five public bathing beaches and quantifies their colonisation by E. coli and Vibrio spp. Nurdles [i.e., microplastics] were heterogeneously distributed along the high tide mark at all five beaches, and each beach contained nurdles that were colonised by E. coli and Vibrio spp. Knowledge of E. coli colonisation and persistence on nurdles should now be used to inform coastal managers about the additional risks associated with plastic debris.
Status of Cleaning up Oil Pollution in Ogoniland, Nigeria:
According to the Civil Society Legislative Advocacy Centre (CISLAC), the clean-up of Ogoniland is bugged with identity crisis, procedures, processes and overheads. Perception of corruption, lack of transparency and accountability, complex decision making, internal crisis of choice between Ogoni and the Niger Delta….The United Nations Environment Programme (UNEP) released its Environmental Assessment of Ogoniland in August 2011 after series of protests of oil spillage in the community that culminated to the death of Ken Sarowiwa and eight others. The report made recommendations to the government, the oil and gas industry and communities to begin a comprehensive cleanup of Ogoniland, restore polluted environments and put an end to all forms of ongoing oil contamination in the region…
Pollution of soil by petroleum hydrocarbons in Ogoniland is extensive in land areas, sediments and swampland. In 49 cases, UNEP observed hydrocarbons in soil at depths of at least 5 metres. At 41 sites, the hydrocarbon pollution has reached the groundwater at levels in excess of the Nigerian standards permitted by National Laws..

The IUCN report published in 2019 looked at primary microplastics – plastics that enter the oceans in the form of small particles, as opposed to larger plastic waste that degrades in the water – released from household and industrial products across seven geographical regions. Sources of primary microplastics include car tyres, synthetic textiles, marine coatings, road markings, personal care products, plastic pellets and city dust. According to the report, between 15 and 31% of the estimated 9.5 m tonnes of plastic released into the oceans each year could be primary microplastics, almost two-thirds of which come from the washing of synthetic textiles and the abrasion of tyres while driving…Synthetic textiles are the main source of primary microplastics in Asia and tyres dominate in the Americas, Europe and Central Asia…. Synthetic clothes could be designed to shed fewer fibres, for example, and consumers can act by choosing natural fabrics over synthetic ones”
The World Health Organization is reviewing microplastics’ potential impact on human health after a study found plastic in 259 bottles of water from 11 different brands bought in nine countries. Microplastics have turned up in seafood, drinking water, beer, honey and sugar, according to studies, but the impact on human health is unclear.Research shows that ingesting microplastics can hurt the ability of planktonic organisms to feed and the ability of fish and marine worms to gain energy from food. Pending bills in New York and California, if successful, would require labels on clothes made from more than 50% synthetic material to tell consumers that these shed plastic microfibers when washed.
Researchers also have zeroed in on how clothes are washed. Outdoor-apparel brand Patagonia found fabrics shed lots of microfibers on the first wash, but few in subsequent washes. That suggests pretreating garments before they are sold could potentially capture and recycle what otherwise goes down consumers’ drains. It also found types of washing machines matter. Jackets washed in top-load washing machines shed seven times as many microfibers as front-loaders.

Joining the FAO/IAEA coordinated research projects in the area of mutation breedinghas led to the development of several barley mutant lines with improved yield and quality under Kuwait’s environmental conditions. As arable land is limited to small areas, 95% of the country’s food and animal fodder is imported. Barley is a preferred crop for cultivation, because it is relatively drought tolerant and therefore one of the most suitable crops for an arid country like Kuwait. Having high yielding home grown crops is among the key objectives of the country’s agricultural programme to enhance food security.
Drought, salinity and diseases have historically limited staple crop productivity in Kuwait. Mutation induction by radiation rapidly increases the genetic diversity necessary to produce new and improved varieties and is thus advantageous over traditional breeding…The best adaptable varieties were identified, and the seeds were subjected to induced mutation using gamma rays.
New mutant lines have been generated and they are now examined for drought and salinity tolerance. The selected mutant lines will be advanced, which then can be multiplied for planting. …One of the major challenges was explaining to farmers the safety of the new mutated barley lines developed. “When they heard that ‘nuclear techniques’ were used to create improved barely seeds, they got scared….

The malign effect of floating plastic debris on seabirds, turtles and other sea creatures is well known. But, as Dr Mincer and Dr Amaral-Zettler have discovered, plastic debris also provides a new habitat for organisms small enough to take advantage of it. The two researchers collected pieces of plastic from various sites in the North Atlantic. They then examined each using DNA analysis, and also an electron microscope, to see what was living on it. Lots of things were. Altogether, they discovered about 50 species of single-celled plant, animal and bacterial life. Each bit of debris was, in effect, a tiny ecosystem….Plastics are energy-rich substances, which is why many of them burn so readily. Any organism that could unlock and use that energy would do well….Less encouragingly, Dr Mincer and Dr Amaral-Zettler also found cholera-like bacteria in their tiny floating ecosystems. Both fish and seabirds act as vectors for cholera (the former bring it into human settlements when caught by fishermen, the latter when resting ashore or nesting), so anywhere that such creatures might pick up cholera bugs is something worth keeping an eye on.
The researchers paint an intriguing picture of the adaptability of nature, and provide another piece of the jigsaw that is the Anthropocene. Conservationists intent on preserving charismatic megafauna have reason to lament the spread of plastics through the ocean. But those interested in smaller critters have been given a whole, new sphere—the plastisphere—to study.
Marine ecology: Welcome to the plastisphere, Economist, July 20, 2013, at 7
But it took a viral video posted on 8 January 2019 to drive home the ecological catastrophe that was unfolding in the Murray-Darling river system in Australia. In the footage, Rob McBride and Dick Arnold, identified as local residents, stand knee-deep among floating fish carcasses in the Darling River, near the town of Menindee. They scoff at authorities’ claims that the fish die-off is a result of the drought. Holding up an enormous, dead Murray cod, a freshwater predator he says is 100 years old, McBride says: “This has nothing to do with drought, this is a manmade disaster.” Arnold, sputtering with rage, adds: “You have to be bloody disgusted with yourselves, you politicians and cotton growers.”
Scientists say McBride probably overestimated the age of the fish. But they agree that the massive die-off was not the result of drought. “It’s about taking too much water upstream [to irrigate farms] so there is not enough for downstream users and the fish,” says Quentin Grafton, an economist specializing in water issues at Australian National University (ANU) in Canberra. The Australia Institute, a Canberra-based think tank, blamed “policy failure and mismanagement” in a 19 January 2019 report, but called drought a catalyst.
Excessive water use has left river flows too low to flush nutrients from farm runoff through the system, leading to large algal blooms, researchers say. A cold snap then killed the blooms, and bacteria feeding on the dead algae sucked oxygen out of the water, This wasn’t supposed to happen. In 2012, the national government adopted the Murray-Darling Basin Plan, touted as a “historic” deal to ensure that enough water remained in the rivers to keep the ecosystem healthy even after farmers and households took their share.
In 2008, the federal government created the Murray-Darling Basin Authority to wrestle with the problem. In 2010, a study commissioned by the authority concluded that farmers and consumers would have to cut their use of river water by at least 3000 but preferably by 7600 gigaliters annually to ensure the health of the ecosystem. Farmers, who saw their livelihoods threatened, tossed the report into bonfires. The final plan, adopted as national law in 2012, called for returning just 2750 gigaliters to the rivers, in part by buying water rights back from users. “It was a political compromise that has never been scientifically reviewed,” Williams says, adding that “climate change was never considered in the plan, which was a dreadful oversight.”..
Grafton says there are also suspicions of widespread water theft; up to 75% of the water taken by irrigators in the northern part of the system is not metered. Farmers are also now recapturing the runoff from irrigated fields that used to flow back into streams, and are increasing their use of ground water, leaving even less water in the system, says Mike Young, an environmental policy specialist at the University of Adelaide in Australia.
In February 2018, such issues prompted a group of 12 academics, including scientists and policy experts, to issue the Murray-Darling Declaration. It called for independent economic and scientific audits of completed and planned water recovery schemes to determine their effects on stream flows. The group, which included Williams and Grafton, also urged the creation of an independent, expert body to provide advice on basin water management. Young, who wasn’t on the declaration, wants to go further and give that body the power to manage the basin’s water, the way central banks manage a country’s money supply, using stream levels to determine weekly irrigation allocations and to set minimum flow levels for every river.

The Tibetan Plateau and its surrounding mountains [the Himalayas], often termed the Third Pole, contain more ice than anywhere outside the Arctic and Antarctic. This region is also the source of the nine largest rivers in Asia, providing fresh water, food, and other ecosystem services to more than 1.5 billion people…In recent decades, air temperature at the Third Pole has warmed significantly faster than the global average…Meanwhile, intensive anthropogenic activities, such as overgrazing, deforestation, urbanization, and expansion of infrastructure projects such as construction of roads, dams, and electrical grids, are causing widespread landcover changes within the region.
Together, these changes are altering the Third Pole’s biogeochemical cycles and pushing the fragile ecosystem toward degradation and possible collapse, which would cause irreversible harm on a regional and global scale. To avoid this, all nations must meet the standards laid out in the Paris Agreement. At the regional level, we strongly urge the relevant nations (including Afghanistan, Bhutan, China, India, Kyrgyzstan, Myanmar, Nepal, Pakistan, and Tajikistan) to cooperate in addressing these impending threats through systematic changes to management policies. Rapid and unprecedented coordination will be necessary, including a regional cooperation treaty and formation of a cross-border biodiversity conservation plan for the Third Pole region. Meanwhile, any infrastructure projects undertaken must be environmentally sustainable, and a practicable grazing management policy should be adopted.

An implantable brain device that literally melts away at a pre-determined rate minimizes injury to tissue normally associated with standard electrode implantation, according to research led by a team from the Perelman School of Medicine at the University of Pennsylvania. …Thin, flexible neural electrode arrays with fully bioresorbable construction based on patterned silicon nanomembranes (Si NMs) as the conducting component.
“Dissolvable silicon electronics offer an unprecedented opportunity to implant advanced monitoring systems that eliminate the risks, cost, and discomfort associated with surgery to extract current devices used for post-operative monitoring,” said senior co-author Brian Litt, MD,….“This study tested the usefulness of temporary, dissolvable monitoring systems capable of providing continuous streams of data for guiding medical care over predetermined periods of time — from days to months — before dissolving.”
The device is made of layers of silicon and molybdenum that can measure physiological characteristics and dissolve at a known rate, as determined by its thickness. For example, the team used the device to record brain waves in rats under anesthesia, as well as voltage fluctuations between neurons (EEGs), and induced epileptic spikes in intact live tissue. A separate experiment demonstrated a complex, multiplexed array made from these materials that could map rat-whisker sensing capabilities at high resolution.
These electrophysiological signals were recorded from devices placed at the surface of the brain cortex (the outer layer of tissue) and the inner space between the scalp and skull. Chronic measurements were made over a 30-day period, while acute experiments demonstrated device operations over three to four hours.
The type of neurophysiologic features measured by the new device are commonly used for diagnosing and treating such disorders as epilepsy, Parkinson’s disease, depression, chronic pain, and conditions of the peripheral nervous system. “….

Stark illustrations of the dangers from chemical weapons can be seen in attacks using toxic industrial chemicals and sarin against civilians and combatants in Syria and toxic industrial chemicals in Iraq, as well as more targeted assassination operations in Malaysia and the United Kingdom, employing VX and novichok nerve agents, respectively. . With the parties to the Chemical Weapons Convention (CWC) convening a Review Conference to address such issues beginning 21 November 2018, we highlight important scientific aspects .
The Chemical Weapons Convention (CWC) is a multilateral treaty in effect since 1997 that proscribes the development, production, stockpiling, transfer, and use of chemical weapons “under any circumstances” and requires their destruction within a specified time period. The CWC allows the use of toxic chemicals for a range of industrial, agricultural, research, medical, pharmaceutical, or other peaceful purposes, including law enforcement, as long as the “types and quantities” of chemicals employed are “consistent with such purposes.” …The Organisation for the Prohibition of Chemical Weapons (OPCW), which is the implementing body of the CWC, comprises the 193 State Parties and a Technical Secretariat that provides technical assistance to States, routinely inspects relevant State and commercial industrial facilities, and monitors activities to ensure compliance. It was awarded the Nobel Peace Prize in 2013 for overseeing and facilitating the verified destruction of most of the declared chemical weapons stocks produced in the last century—to date totaling more than 96% (69,750 metric tons) of the declared stockpiles of chemical agents.
Although the CWC includes three schedules of toxic chemicals for the application of verification measures, the scope of the CWC is not constrained to these schedules but by its General Purpose Criterion (GPC), which prohibits misuse of toxic chemicals based on intent rather than on this limited list of chemicals. [This GPC makes it possible to widen the authority of the OPCW. More, specifically issues to consider include]:
1) Riot control agents (RCAs). The CWC defines RCAs—such as tear gas and pepper spray—as “any chemical not listed” in one of its three schedules that can produce “rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.”…However, a recurring concern documented by the medical community and human rights monitors has been the widespread misuse of RCAs by police and security forces in excessive quantities, including in hospitals, prisons, homes, and automobiles, where targeted individuals cannot disperse. In such situations, serious injury or death can result from toxic properties of chemicals or from asphyxiation… [It is important to clarify] the nature and scope of “law enforcement” activities and develop guidance as to “types and quantities” of RCAs that can legitimately be used in such circumstances
2) Delivery systems… capable of delivering far greater amounts of RCAs (and potentially other toxic chemicals) over wider areas or more extended distances than current standard law enforcement delivery mechanisms, such as handheld sprays, grenades, and single launched projectiles. Such new systems include large-capacity spraying devices, automatic grenade launchers, multibarrel projectile launchers, large-caliber RCA projectiles, and unmanned ground or aerial vehicles capable of carrying spraying devices or projectile launchers. ..
3) Incapacitating chemical agent (ICA) weapons. Although the CWC permits use of appropriate types and quantities of RCAs for law enforcement, certain countries have conducted research into weapons employing other distinct toxic chemicals, so-called ICAs. Not separately defined under the CWC, ICAs can be considered as a range of toxic chemicals—only one of which [3-quinuclidinyl benzilate (BZ) and two of its immediate precursors] is currently scheduled—including anesthetics and other pharmaceutical chemicals that are purportedly intended to act on the body’s core biochemical and physiological systems, notably the central nervous system (CNS), to cause prolonged but nonpermanent disability. Such CNS-acting chemicals can produce unconsciousness, sedation, hallucination, incoherence, disorientation, or paralysis…An aerosolized mixture of two anesthetics—carfentanil and remifentanil—employed by Russian security forces to end the Moscow theatre siege of October 2002 caused the deaths of 125 of the 900 hostages…
Other chemical production facilities (OCPFs) are chemical plants that do not currently produce, but are capable of manufacturing, chemical warfare agents or precursors. At present, a small fraction of declared OCPFs are selected for verification by the OPCW; the Review Conference should consider authorizing a substantial increase in OCPF inspections per year. …Biological and biologically mediated processes for production of discrete organic chemicals Some products and processes used by the biomanufacturing industry are as relevant to the CWC as those used by other OCPF facilities The OPCW should build on the considerable progress made toward developing a network of designated laboratories for the analysis of biomedical and biological samples. Advances in other fields could also facilitate more effective evidence collection, for example, exploring the potential of unmanned aerial vehicles to support reconnaissance, detection, and chain of custody.
Excerpts from Michael Crowley at al., Preventing Chemical Weapons as Sciences Converge, Science, Nov. 16, 2018
The mosquitoes are being fitted with a piece of dna called a gene drive. Unlike the genes introduced into run-of-the-mill genetically modified organisms, gene drives do not just sit still once inserted into a chromosome. They actively spread themselves, thereby reaching more and more of the population with each generation. If their effect is damaging, they could in principle wipe out whole species.. If gene drives were to condemn to a similar fate the mosquitoes that spread malaria, a second of humankind’s great scourges might be consigned to history.
Gene drives can in principle be used against any creatures which reproduce sexually with short generations and aren’t too rooted to a single spot. The insects that spread leishmaniasis, Chagas disease, dengue fever, chikungunya, trypanosomiasis and Zika could all be potential targets. So could creatures which harm only humankind’s dominion, not people themselves. Biologists at the University of California, San Diego, have developed a gene-drive system for Drosophila suzukii, an Asian fruitfly which, as an invasive species, damages berry and fruit crops in America and Europe. Island Conservation, an international environmental ngo, thinks gene drives could offer a humane and effective way of reversing the damage done by invasive species such as rats and stoats to native ecosystems in New Zealand and Hawaii.
Such critics fear that the laudable aim of vastly reducing deaths from malaria—which the World Health Organisation puts at 445,000 a year, most of them children—will open the door to the use of gene drives for far less clear-cut benefits in ways that will entrench some interests, such as those of industrial farmers, at the expense of others. They also point to possible military applications: gene drives could in principle make creatures that used not to spread disease more dangerous… The ability to remove species by fiat—in effect, to get them to remove themselves—is, like the prospect of making new species from scratch, a power that goes beyond the past ambit of humankind.
Gene drives based on crispr-Cas9 could easily be engineered to target specific bits of the chromosome and insert themselves seamlessly into the gap, thus ensuring that every gamete gets a copy . By 2016, gene drives had been created in yeast, fruitflies and two species of mosquito. In work published in the journal Nature Biotechnology in September, Andrea Crisanti, Mr Burt and colleagues at Imperial showed that one of their gene drives could drive a small, caged population of the mosquito Anopheles gambiae to extinction—the first time a gene drive had shown itself capable of doing this. The next step is to try this in a larger caged population.
There are also worries about how gene drives might be used to create a weapon. …The need to find ways to guard against such attacks is one of the reasons that the Pentagon’s Defence Advanced Research Projects Agency (darpa) gives for its work on gene drives. Renee Wegrzyn, programme manager for darpa’s “Safe Genes” project, says the work is to prevent “technological surprise”, whether in the form of an unintended consequence or nefarious use. One of the academic teams she funds has made progress in developing anti-crispr enzyme systems that one day might be able to inhibit a drive’s operation.
Oversight needs not just to bring together a range of government agencies; it requires co-operation between governments, too. The Cartagena Protocol on Biosafety, which entered into force under the un Convention on Biological Diversity (cbd) in 2003, provides controls on the transfer of genetically modified organisms. But how it applies to gene drives is unclear—and besides, America has never ratified the convention. An attempt to ban gene-drive research through the cbd, which was backed by the etc Group and other ngos, failed at the convention’s biennial meeting in Cancún in 2016…Like the reintroduction of vanished species advocated by the rewilding movement, gene-drive technology will provide new arenas for the fight between those who wish to defend nature and those who wish to tame it.
Excerpts from Gene Drives: Extinction on Demand, Economist, Nov. 10, 2018, at 24
Many envisioned environmental applications of newly developed gene-editing techniques such as CRISPR might provide profound benefits for ecosystems and society. But depending on the type and scale of the edit, gene-edited organisms intentionally released into the environment could also deliver off-target mutations, evolutionary resistance, ecological disturbance, and extinctions. Hence, there are ongoing conversations about the responsible application of CRISPR, especially relative to the limitations of current global governance structures to safeguard its use, Largely missing from these conversations is attention to local communities in decision-making. Most policy discussions are instead occurring at the national or international level even though local communities will be the first to feel the context-dependent impacts of any release. ..
CRISPR gene editing and other related genetic technologies are groundbreaking in their ability to precisely and inexpensively alter the genome of any species. CRISPR-based gene drives hold particular import because they are designed to rapidly spread genetic changes—including detrimental traits such as infertility—through populations of sexually reproducing organisms, to potentially reach every member of a species. Villages in Burkina Faso are weighing the release of gene drive–bearing mosquitoes that could suppress malaria. Nantucket Island residents in the United States are considering the release of genetically engineered white-footed mice to deplete Lyme disease reservoirs. New Zealand communities are discussing the possibility of using genetic methods to eliminate exotic predators.
But what if a gene drive designed to suppress an invasive species escaped its release site and spread to a native population? Or if a coral species gene edited to better adapt to environmental stressors dominated reef ecosystems at the expense of a diversity of naturally evolving coral species and the fish that depend on them ? The gravity of these potential outcomes begs the question: Should humans even be meddling with the DNA of wild organisms? The absence of generally agreed on answers can be used to support calls for moratoria on developing and releasing genetically altered organisms, especially those with gene drives (6).
However, the promising benefits of environmental gene editing cannot be dismissed. Gene drives may provide a long-sought-after tool to control vectors of infectious disease and save millions of human lives. Projects to conserve ecosystems or promote species resilience are often intended to repair human-inflicted environmental damage. Put simply, either using this technology irresponsibly or not using it at all could prove damaging to humans, our welfare, and our planet.
At the international level, the Convention on Biological Diversity (CBD) has enlisted an expert technical panel to, in part, update its Cartagena Protocol (of which the United States is not a party) that oversees transboundary transport of living modified organisms to accommodate gene drive–bearing organisms. The International Union for the Conservation of Nature (IUCN) is also developing policy to address the release of gene-edited organisms. Although the CBD and the IUCN offer fora to engage diverse public feedback, a role largely fulfilled by civil society groups, none of these agencies currently use the broad and open deliberative process we advocate….
Different societal views about the human relationship to nature will therefore shape decision-making. Local community knowledge and perspectives must therefore be engaged to address these context-dependent, value-based considerations. A special emphasis on local communities is also a matter of justice because the first and most closely affected individuals deserve a strong voice in the decision-making process…Compounding this challenge is that these decisions cannot be made in isolation. Organisms released into local environments may cross regional and even international borders. Hence, respect for and consideration of local knowledge and value systems are necessary, but insufficient, to anticipate the potentially ramifying global implications of environmental release of gene-edited organisms. What is needed is an approach that places great weight on local perspectives within a larger global vision…
The needs of ecosystems could also be given voice to inform deliberative outcomes through custodial human proxies. Inspired by legislative precedent set by New Zealand, in which the Whanganui River was granted legal “personhood,” human representatives, nominated by both an international body like the IUCN and the local community, would be responsible for upholding the health and interests of the ecosystems in question. Proposed gene-editing strategies would be placed in the larger context of alternative approaches to address the public health or environmental issue in question…
An online registry for all projects intending to release genetically engineered organisms into the environment must be created. Currently, no central database exists for environmental gene-editing applications or for decision-making outcomes associated with their deployment, and this potentially puts the global community at risk…A global coordination task force would be charged with coordinating multiple communities, nations, and regions to ensure successful deliberative outcomes. As a hypothetical example, genetic strategies to eliminate invasive possums from New Zealand must include representatives from Australia, the country likely to be affected should animals be transported outside the intended range. Similarly, the African Union is currently deliberating appropriate governance of gene drive–bearing mosquitoes to combat malaria on a regional scale.

The Soviet Union during the 1960s and 70s dumped several hundred containers with solid radioactive waste in the Blagopoluchie Bay in Novaya Zemlya. Back then, these waters were covered with ice overwhelming parts of the year. Today, that is quickly changing. The bay located in the northern part of the Russian Arctic archipelago is now ice-free increasing parts of the year. With the retreating ice follow new species.
Researchers from the Russian Shirshov Institute of Oceanology have comprehensively studied the eco system of the bay for several years. Among their key findings is a quickly growing number of snow crabs. In this year’s research expedition to the remote waters, the researchers were overwhelmed by the numbers. According to the institute, the crab invasion can be described «as avalanche».
The number of crabs in the area is now estimated to almost 14,000 per hectare, the institute informs. With the help of underwater photo and video footage, the researchers have studied how the crab expansion is leading to a other reduction in other marine life on the sea bottom. A further spread in the other parts of the Kara Sea is imminent, and the Russian Fisheries Agency (Rosrybolovstvo) believe that the Kara Sea will ultimately become an area with commercial crab fishing.
But Kara seas is a major nuclear waste dump…No major leakage from the radioactive materials have so far been registered. Soviet authorities are believed to have dumped about 17,000 containers with solid radioactive wastes in Arctic waters and primarily in the Kara Sea. More than 900 containers are located on the bottom of the Blagopoluchie Bay. Also a number of reactor compartments were dumped, as well as three nuclear subs and other nuclear materials.

Innovator Cranfield University, U.K.: Putting down the toilet lid activates a dry flush. The motion turns a set of gears that drop feces and urine into a pan, where they are separated and either combusted into ash that can be thrown away or filtered into clean water that could be used to water plants, for instance, though not drinking. It was one of the few completely standalone toilets at the expo, able to function without links to water, sewer or electric lines.
The Innovator: Helbling Group, Switzerland: Helbling’s self-contained toilet system
Similar to other models, this toilet is a mostly self-contained system that transforms waste into clean water and a form of charcoal. But its makers, who were contracted by the Gates Foundation to develop this model, also had modern design in mind: A sleek, black-and-white prototype includes a touchpad for the flush and a container that can be detached to dump out excess water. While it doesn’t have to connect to water or sewer lines, one limit is that the model still needs electricity from an outside source
Sedron Technologies makes the Janicki Omni Processor, a small-scale waste-treatment plant that can filter wet fecal matter so thoroughly that the resulting water is not only free of bacteria and viruses but also safe for drinking. At its highest capacity the plant can manage waste for up to 500,000 people, the same range as two other plants featured at the expo. A trial has been running in Dakar, Senegal, over the past three years to identify and fix technical problems.

An international law enforcement operation against maritime pollution has revealed hundreds of violations and exposed serious cases of contamination worldwide. Codenamed 30 Days at Sea, the month-long (1-31 October) operation saw some 276 law enforcement and environmental agencies across 58 countries detect more than 500 offences, including illegal discharges of oil and garbage from vessels, shipbreaking, breaches of ship emissions regulations, and pollution on rivers and land-based runoff to the sea. More than 5200 inspections have resulted in at least 185 investigations, with arrests and prosecutions anticipated.
“Criminals believe marine pollution is a low-risk crime with no real victims. This is a mistake and one which INTERPOL and our partners are addressing as demonstrated by this operation,” said INTERPOL Secretary General Jürgen Stock. Cases of serious contamination included the dumping of animal farm waste in Philippine coastal waters where local communities collect shellfish and children play. In Germany, a vessel discharged 600 litres of palm oil into the sea. Ghana uncovered gallons of waste oil in large bottles thought to be illegally dumped at sea. Authorities prevented an environmental disaster in Albania by securing waters around a sinking vessel containing some 500 litres of oil. Similarly, the pollution threat resulting from the collision of two ships in French waters was contained thanks to preventive action during the operation.
Innovative technologies permitted authorities to detect offences, including the use of satellite images (in Argentina and Sweden), aerial surveillance (Canada and Italy), drones (Nigeria, Indonesia and Pakistan) and night vision cameras.

The study, “Scientific Assessment of Ozone Depletion: 2018”, is the latest in a series of reports, released every four years, which monitor the recovery of ozone in the stratosphere, a layer that protects life on Earth from harmful layers of ultraviolet rays from the sun. It shows that the concentration of ozone-depleting substances continues to decrease, leading to an improvement in the layer since the previous assessment carried out in 2014.
Ozone in parts of the stratosphere has recovered at a rate of 1-3 percent since 2000 and, at projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s, followed by the Southern Hemisphere in the 2050s and polar regions by 2060.
This is due to internationally agreed actions carried out under the historic Montreal Protocol, which came into being over 30 years ago in response to the revelation that chlorofluorocarbons (CFCs) and other ozone-depleting substances – used in aerosols, cooling and refrigeration systems, and many other items – were tearing a hole in the ozone layer and allowing dangerous ultraviolet radiation to flood through.
Next year, the Protocol is set to be strengthened with the ratification of the Kigali Amendment, which calls for the future use of powerful climate-warming gases in refrigerators, air conditioners and related products to be slashed…The writers of the report found that, if the Kigali Amendment is fully implemented, the world can avoid up to 0.4 percent of global warming this century, meaning that it will play a major role in keeping the global temperature rise below 2°C.

On September 15, 2018 indigenous federations from the Amazonian Loreto region of northern Peru scored a small victory in the fight for community rights. Representatives from four federations signed an agreement with the Peruvian government and the state-owned enterprise PetroPerú that acknowledges prior consultation as part of the new contracting process for petroleum Block 192. Under the new agreement, Block 192 will undergo a community consultation process before PetroPerú awards a new contract for operating the oil field…
Under the formal resolution with Prime Minister César Villanueva, the Ministry of Energy and Mining, and PetroPerú, the government will complete the community consultation for Block 192 between December 2018 and March 2019.
Extending across the Tigre, Corrientes, Pastaza and Marañón river basins in Peru’s remote Loreto province, Block 192 is the largest-yielding oil field in Peru, accounting for 17 percent of the country’s production. The government plans to continue production of oil at the block for another 30 years, adding to the almost 50 years of oil activity in the region. The oil field is currently operated by Canadian-based Frontera Energy, whose contract with PetroPerú is set to expire in September 2019.
American-based Occidental Petroleum discovered oil in the region in 1972 and a succession of companies, including the Dutch-Argentinian conglomerate Pluspetrol, left Block 192 (previously Block 1-AB) heavily polluted. While Peru’s Agency for Environmental Assessment and Enforcement fined Pluspetrol for violations, the Peruvian government remains in a protracted legal fight with the oil giant. A majority of the fines are outstanding and Pluspetrol denies any wrongdoing, despite settling with a local community in 2015.
For over 40 years, the indigenous Kichwa, Quechua, Achuar, and Urarina peoples who live near the oil field have been exposed to salts, heavy metals and hydrocarbons. According to a 2018 toxicology study by Peru’s National Center for Occupational Health and Environmental Protection for Health, over half of the indigenous residents in the region’s four basins have blood lead levels that surpass international recommended limits. A third have levels of arsenic and mercury above the levels recommended by Peru’s Ministry of Health…
The actual cost of cleaning up Block 192, along with neighboring Block 8, would approach $1 billion. To make matters more challenging, the $15 million fund of Peruvian government is almost exhausted..”
More than 60,000 tons of highly radioactive spent nuclear fuel is stored on the shores of four of the five Great Lakes at the Border between United States and Canada — in some cases, mere yards from the waterline — in still-growing stockpiles…It remains on the shorelines because there’s still nowhere else to put it…
The nuclear power industry and its federal regulator, the U.S. Nuclear Regulatory Commission, point to spent nuclear fuel’s safe on-site storage over decades. But the remote possibility of a worst-case scenario release — from a natural disaster, a major accident, or an act of terrorism — could cause unthinkable consequences for the Great Lakes region. Scientific research has shown a radioactive cloud from a spent fuel pool fire would span hundreds of miles, and force the evacuation of millions of residents in Detroit, Chicago, Cleveland, Toronto or other population centers, depending on where the accident occurred and wind patterns.
For five years, Michigan residents, lawmakers, environmental groups and others around the Midwest have, loudly and nearly unanimously, opposed a planned Canadian underground repository for low-to-medium radioactive waste at Kincardine, Ontario, near the shores of Lake Huron. Meanwhile, spent nuclear fuel, vastly more radioactive, sits not far from the shores of four Great Lakes — Michigan, Huron, Erie and Ontario — at 15 currently operating or former nuclear power plant sites on the U.S. side. In Michigan, that includes Fermi 2; the Donald C. Cook nuclear plant in Berrien County; the Palisades nuclear plant in Van Buren County, and the former Big Rock Point nuclear plant in Charlevoix County, which ceased operation in 1997 and where now only casks of spent nuclear fuel remain.
Neither the U.S. nor the Canadian government has constructed a central collection site for the spent nuclear fuel. It’s not just a problem in the Great Lakes region — more than 88,000 tons of spent nuclear fuel, an amount that is rising, is stored at 121 U.S. locations across 39 states.
Spent nuclear fuel isn’t only radioactive, it continues to generate heat. It requires storage in pools with circulating water for typically five years before it can be moved into so-called dry-cask storage — concrete-and-steel obelisks where spent fuel rods receive continued cooling by circulating air.In practice, however, because of the high costs associated with transferring waste from wet pools to dry casks, nuclear plants have kept decades worth of spent fuel in wet storage. Plant officials instead “re-rack” the pools, reconfiguring them to add more and more spent fuel, well beyond the capacities for which the pools were originally designed.
Only in recent years have nuclear plants stepped up the transition to dry cask storage because there’s no room left in the wet pools. Still, about two-thirds of on-site spent nuclear fuel remains in wet pools in the U.S….That’s a safety concern, critics contend. A catastrophe or act of terrorism that drains a spent fuel pool could cause rising temperatures that could eventually cause zirconium cladding — special brackets that hold the spent fuel rods in bundles — to catch fire. Such a disaster could be worse than a meltdown in a nuclear reactor, as spent nuclear fuel is typically stored with nowhere near the fortified containment of a reactor core.
At Fukushima…what almost happened — at the plant’s Unit 4 spent-fuel pool that gives nuclear watchdogs nightmares. A hydrogen explosion four days into the disaster left the building housing the Unit 4 spent-fuel pool in ruins. The pool was seven stories up in a crumbling, inaccessible building. It “was so radioactive, you couldn’t put people up there,” von Hippel said. “For about a month after Fukushima, people didn’t know how much water was in the pool. They were shooting water up there haphazardly with a hose, trying to drop it by helicopter.” Two weeks after the earthquake and tsunami, the Japanese Atomic Energy Commission secretly conducted a worst-case scenario study of the ongoing disaster. The biggest fear that emerged: that a self-sustaining fire would start in the Unit 4 spent fuel pool, spreading to the nearby, damaged reactors. That, they found, would release radiation requiring evacuations as far away as 150 miles, to the outskirts of Tokyo and its more than 13.4 million residents. “That was the devil’s scenario that was on my mind,” Chief Cabinet Secretary Yukio Edano said during a special commission’s 2014 investigation of the accident.“Common sense dictated that, if that came to pass, then it was the end of Tokyo.” What kept the spent fuel rods covered with water in Unit 4 was a miraculous twist of fate: The explosion had jarred open a gate that typically separated the Unit 4 spent fuel pool from an adjacent reactor pool. “Leakage through the gate seals was essential for keeping the fuel in the Unit 4 pool covered with water,” a 2016 report on the Fukushima accident by the U.S. National Academies of Sciences, Engineering and Medicine concluded. “Had there been no water in the reactor well, there could well have been severe damage to the stored fuel and substantial releases of radioactive material to the environment.”
The U.S. nuclear industry sees Fukushima differently — in some ways as a success story. “At Fukushima, you not only had a tsunami, you blew up the buildings … and you still did not drain the pool,” said Rod McCullum, senior director for fuel and decommissioning at the Nuclear Energy Institute, the trade association for nuclear utilities in the U.S. “Those pools and those casks withstood explosions and earthquakes and tsunamis, all on the same day.” A scenario where a fire can occur by the draining of water from a spent-fuel pool “has never been demonstrated,” McCullum said. He noted safety measures added in the U.S. since Fukushima include the ability to provide extra pumps and water supplies, in minutes or hours, should a spent fuel pool become breached and lose water — even if the disaster required that the resources be brought in by air from farther away….
Because nuclear power is much more widely used in Canada — the province of Ontario alone has 20 nuclear reactors at three plants — it also generates much more nuclear waste. In Ontario, nearly 52,000 tons of spent nuclear fuel is stored on-site at nuclear plants along Lakes Huron and Ontario.“There’s a huge amount of high-level, radioactive waste stored right along the water,” said Edwards, the president of the nonprofit Canadian Coalition for Nuclear Responsibility Like the U.S., Canada is seeking a long-term storage solution that will involve a central underground repository. Unlike the U.S., the Canadian government is seeking willing hosts, promising jobs and economic activity. …Even if a central repository is one day approved, another complication arises — how to get two generations of the most dangerous industrial waste man has ever created from sites all over the country to one point….
Germany, in the 1980s, tried using an abandoned salt and potash mine to store barrels of nuclear waste over 30 years, the Asse II mine. It’s now prompting a cleanup that may take 30 years and cost nearly $12 billion U.S. dollars. The government has disputed the contention of workers at the mine that they were exposed to excessive levels of radiation, causing an unusual number of cancers….Nuclear power is projected to drop as a percentage of the world’s power generation mix from 10 percent in 2017 to just 5.6 percent by 2050, a report issued by the International Atomic Energy Agency this summer found…
If central repository solutions aren’t found, within years, the re-licensing of some early dry-cask storage facilities will come into play, as they meet a lifespan they were never expected to reach. “The age of nuclear power is winding down, but the age of nuclear waste is just beginning,” Edwards said.

In the aftermath of the Fukushima nuclear disaster in 2011, Naraha decided to oppose nuclear energy and call for the closure of the Fukushima No. 2 nuclear power plant that it co-hosts on the coast of the prefecture. Since the 1970s, the town has been home to the No. 2 plant, which first went into service in 1982. For decades, Naraha has received central government grants and subsidies for hosting the No. 2 plant, as well as tax revenues from TEPCO and its affiliates operating in the town.The plant also employed 860 people, many of them from Naraha and its surrounding communities.
Naraha had a population of about 8,000 before the Great East Japan Earthquake and tsunami caused the triple meltdown at TEPCO’s Fukushima No. 1 nuclear plant in March 2011. The crippled plant is located within 20 kilometers from Nahara. The quake and tsunami also created a scare at the No. 2 plant by leaving the facility with only a limited power supply from external sources and emergency diesel generators to cool the reactors. But the plant brought the situation under control.
After long remaining silent about the fate of the No. 2 plant, TEPCO decided to retire all of its four reactors, which were approaching their legal operating limit of 40 years. If the power company wanted to continue operations at the plant, it would have to spend hundreds of billions of yen on upgrades to meet the more stringent safety standards that were set after the accident at the No. 1 plant…
Although Naraha and Tomioka officials share concerns about their municipalities’ financial futures, they see a silver lining in the situation at the Fukushima No. 1 nuclear plant. Both towns have served as front-line bases for workers involved in decommissioning of the stricken plant. About 5,000 workers a day who are involved in the decommissioning effort provide steady business for convenience stores and other shops in the two towns. Business hotels, dorms and apartment buildings have been built in the towns and neighboring communities to accommodate the workers. Work to dismantle the No. 1 plant is expected to take decades to complete. Local officials said the closure of the No. 2 plant could bring about a similar economic boon. “Decommissioning can become a major industry,” Naraha Mayor Matsumoto said.

THE ASAHI SHIMBUN, October 18, 2018
Russian scientists have said that radioactive waste sunk in the Arctic by the Soviet Navy has not leaked any contamination…. Data on the scuttled cargoes –– which includes several thousand containers of radioactive waste, as well as an entire nuclear submarine –– come from a month-and-a-half-long expedition in the Kara Sea conducted by the Russian Academy of Sciences Institute of Oceanology. Mikhail Flint, the institute’s head, told reporters last week that scientists on the expedition had managed to significantly improve their maps of where the sunken waste lies, especially in the area of the Novaya Zemlya archipelago, a former Soviet nuclear bomb testing site. From Novaya Zemlya’s craggy coast, the expedition conducted additional research mapping radioactive hazards in the White Sea, and then progressed to the Laptev Sea some 2000 nautical miles to the east.
Since the first decades of the 2000s, these mapping and measuring expeditions have taken place on an annual basis. Environmentalists fear the waste could eventually rupture and spoil thousands of square kilometers of fertile Arctic fishing grounds.
Beginning in 1955 and continuing until the early 1990s, the Russian Navy dumped enormous amounts of irradiated debris — and it one case an entire nuclear submarine — into the waters of the Arctic. It was not, however, until 2011 that the Russian government admitted this on an international level. That year, Moscow shared with Norwegian nuclear officials the full scope of the problem. The list of sunken objects was far more than had initially been thought, and included 17,000 containers of radioactive waste; 19 ships containing radioactive waste; 14 nuclear reactors, including five that still contain spent nuclear fuel; the K-27 nuclear submarine with its two reactors loaded with nuclear fuel, and 735 other pieces of radioactively contaminated heavy machinery.

Kapuas, Indonesia’s longest river support somes 3m people…One reason that the water is so murky is deforestation. Since the 1970s logging has enriched locals while stripping away the vegetation that held the soil in place. The Centre for International Forestry Research (CIFOR) found that between 1973 and 2010 over 100,000 square kilometres of forest was lost on Kalimantan, or a third of the original coverage. A national moratorium that began in 2011 has done little to still the axes. As a result, torrential tropical rains wash lots of loose earth into the Kapuas.
Illegal gold-mining compounds the problem. Locals tear up the riverbed with diggers or blast the banks with high-pressure hoses, then sieve the mud for gold. Mercury, which the miners use to separate gold from sediment, but which is poisonous to humans and fish alike, leaks into the river.
The riverbank is punctuated with corrugated-iron towers, which emit birdsong from loudspeakers. These are designed to lure swiftlets, who make their nests with saliva. The nests of swiftlets are considered a delicacy and aphrodisiac by many Chinese.* Deane, a shop owner, built his tower last December after seeing others do the same. He sells the nests to a wholesaler for about 15m rupiah ($1,025) a kilogram…
In Kapuas Hulu, an upstream district, half the population rely on the river for drinking water. A quarter have no toilet. Even where bathrooms do exist along the river, they are often floating cubicles with a hole in the floorboards. Cows and goats, living in wooden riverside cages, also defecate straight into the Kapuas…
The Kapuas passes through seven districts. Midstream ones, such as Sintang and Sanggau, earn hefty tax revenues by encouraging palm-oil plantations. But downstream districts suffer from the resulting silt, traffic and run-off without receiving any of the benefits. The same problem occurs at a village level. Mr Hadi says that fishing by sprinkling poisonous leaves on the water (the stricken fish float to the surface) is forbidden but other village heads do not enforce the rules…
A study by CIFOR on the income of villagers living near the Kapuas river found that the best-paid palm-plantation workers earned 50% more than the most successful fishermen. (Gold miners made three times as much—and spent more on education.)…But the environmental damage is plain to see. The river here is brown, clouded by silt. A study published in 2016 found that levels of phosphates in the water, from fertilisers and villagers washing themselves with soap, are highest near urban areas and palm plantations.
Down in Pontianak, the river water is darker still, occasionally brightened by oil slicks. Water bottles and instant-noodle packets cling together to form plastic islands.

*According to Wikipedia: Authentic bird’s-nest soup is made from nests of some species of swiftlet. Instead of twigs, feathers and straw, these swiftlets make their nest only from strands of their gummy saliva, which hardens when exposed to air. Once the nests are harvested, they are cleaned and sold to restaurants. Eating swiftlet nest material is believed to help maintain skin tone, balance qi (“life energy”) and reinforce the immune system… (Dictionary of Traditional Chinese Medicine, The History of Chinese Medicine and the Nutrition Table).
High levels of a radioactive material and other contaminants have been found in water from a West Australian fracking site* but operators say it could be diluted and fed to beef cattle. The revelations illustrate the potential risks associated with the contentious gas extraction process known as fracking, or hydraulic fracturing, as the Turnbull government pressures states to ease restrictions on the industry and develop their gas reserves.
The findings were contained in a report by oil and gas company Buru Energy that has not been made public. It shows the company also plans to reinject wastewater underground – a practice that has brought on seismic events when used in the United States.
Buru Energy has been exploring the potentially vast “tight gas” resources of the Kimberly region’s Canning Basin. The work was suspended when the WA government last year introduced a fracking moratorium, subject to the findings of a scientific inquiry.
In a submission to the inquiry obtained by the Lock the Gate Alliance, Buru Energy said a “relatively high concentration” of Radium-228…The samples exceeded drinking water guidelines for radionuclides. However Buru Energy said samples collected from retention ponds were below guideline levels and the water posed “no risk to humans or animals”. Water monitoring also detected elevated levels of the chemical elements barium, boron and chloride….Buru Energy said while the water was not suitable for human consumption, the “reuse of flowback water for beef cattle may also be considered”. The water did not meet stockwater guidelines but this could be addressed “through dilution with bore water”.
The company’s development in the Yulleroo area of the basin could lead to 80 wells operating over 20 years….The company insists its fracking fluids are non-toxic and to illustrate its safety, executive chairman Eric Streitberg drank the fluid at the company’s 2016 annual general meeting.
Excerpt from Nicole Hasham Radioactive water reignites concerns over fracking for gas, Sydney Morning Herald, June 24, 2018
*Fracking, which involves injecting water mixed with chemicals and sand deep underground in order to fracture rock and release oil and gas, generates large amounts of wastewater. … In some cases, improper handling of this waste water has resulted in the release of radioactive fracking waste that has contaminated streams and rivers, Science Magazine, Apr 9, 2015
The levels of lead and mercury in the sea reduce noticeably following concrete actions to limit their release, recent research at the IAEA using nuclear techniques has shown. The banning of leaded petrol and the closure of a mercury discharging plant have led to decreases in pollution levels over 10-15 years.
This is the case for lead, which when consumed by fish which is in turn eaten by people, can cause damage to the human nervous system and internal organs. Many different activities such as mining or smelting in metallurgy and the burning of coal as well as lead’s use in batteries, paint, ceramics and other everyday items can release it into the environment. The biggest source of lead pollution in the last century was related to the use of leaded petrol.
As part of efforts to develop new methods to determine the source and levels of lead pollution, researchers at the IAEA Environment Laboratories analysed sediments from the Baltic Sea and the Caribbean Sea. In mapping the pollution history in a sediment core from the Baltic coast of Germany, researchers could clearly observe that within 10 to 15 years of phasing out lead in petrol by 1996, lead pollution levels in the sea had decreased..
In addition, IAEA researchers have successfully developed methods to use lead isotope ratios to determine the source of lead pollution and assess whether it is naturally present or the result of anthropogenic activities, since natural and anthropogenic lead sources will show different isotopic fingerprints and isotope compositions….
IAEA scientists’ analysis of a dated sediment core in a Caribbean bay shows total mercury (Hg) levels rapidly decreased after the closure of a discharging plant…Mercury was used in an alkali plant there as a catalyser, and in the 1970s, high concentrations were found in water, sediments and marine organisms as a result of discharges from the plant. Years later, after the plant had been closed, IAEA researchers showed, by analysing sediment core taken from the bay, that levels of total mercury had started to decrease. While remnants of this pollution are still buried in the sediment, acute toxicity has been greatly reduced.

May 2018: The environmental damage around the site of two Royal Dutch Shell oil spills in Nigeria a decade ago has worsened significantly after years of delay to cleanup efforts, according to a report that the oil giant has been accused of trying to shield from public view. The spills from a ruptured Shell pipeline spewed thousands of barrels of oil over parts of the Bodo fishing community in the crude-rich Niger Delta. Although the company in 2015 reached an out-of-court settlement with the local community, admitting to liability and agreeing to pay £55 million, or around $80 million at the time, in compensation, controversy around the case has remained.
A United Nations body, in a 2011 report, found extensive environmental damage around Bodo. Four years later, an assessment to prepare the cleanup found soil contamination had worsened while cleanup efforts languished and illegal refining and oil theft added to pollution in the area, according to an academic paper published last month. That has left the community facing potentially toxic pollution and “catastrophic” damage to the environment, the paper said. The 2015 analysis was commissioned by the Bodo Mediation Initiative, a consortium established to oversee the cleanup in the area. Shell is a member of the group along with local stakeholders.
At least one of the authors urged the findings to be widely distributed because they pointed to significant health risks to the local community. Kay Holtzmann, the cleanup project’s former director, said in a letter reviewed by the Journal that Shell had denied him permission to publish the study’s results in a scientific journal.
But the academic paper* said the site survey contained new facts. The average surface soil contamination in Bodo had tripled since the original U.N. probe,the paper said. Out of 32 samples taken from the top two inches of soil in the area around Bodo, only one was within Nigeria’s legally acceptable limit for oil contamination, the paper added.

Most of the drinking water consumed in Beijing has travelled 1,432km (895 miles), roughly the distance from New York to Orlando, Florida. Its journey begins in a remote and hilly part of central China at the Danjiangkou reservoir, on the bottom of which lies the drowned city of Junzhou. The water gushes north by canal and pipeline, crosses the Yellow river by burrowing under it, and arrives, 15 days later, in the water-treatment plants of Beijing. Two-thirds of the city’s tap water and a third of its total supply now comes from Danjiangkou.
This winter and spring, the reservoir was the capital’s lifeline. No rain or snow fell in Beijing between October 23rd 2017 and March 17th 2018—by far the longest drought on record. Yet the city suffered no supply disruptions, unlike Shanxi province to the west, where local governments rationed water. The central government is exultant, since the project which irrigates Beijing was built at vast cost and against some opposition.
The South-to-North Water Diversion Project—to give the structure its proper name—is the most expensive infrastructure enterprise in the world. It is the largest transfer of water between river basins in history, and China’s main response to its worst environmental threat, which is (despite all the pollution) lack of water.
The route between Beijing and Danjiangkou, which lies on a tributary of the Yangzi, opened in 2014. An eastern route opened in 2013 using the ancient Grand Canal between Hangzhou and the capital. (Jaw-dropping hydrological achievements are a feature of Chinese history.) A third link is planned on the Tibetan plateau, but since that area is prone to earthquakes and landslides, it has been postponed indefinitely…
Downstream from Danjiangkou, pollution has proved intractable. By diverting water from the Yangzi, the project has made the river more sluggish. It has become less able to wash away contaminants and unable to sustain wetlands, which act as sponges and reduce flooding. To compensate for water taken from their rivers, local governments are also building dams wherever they can to divert it back again. Shaanxi province, for example, is damming the Han river to transfer water to its depleted river Wei….Worst of all, the project diverts not only water but money and attention from China’s real water problem: waste and pollution.

Charcoal is one of the biggest informal businesses in Africa. It is the fuel of choice for the continent’s fast-growing urban poor, who, in the absence of electricity or gas, use it to cook and heat water. According to the UN, Africa accounted for three-fifths of the world’s production in 2012—and this is the only region where the business is growing. It is, however, a slow-burning environmental disaster.
In Nyakweri forest, Kenya, the trees are ancient and rare. Samwel Naikada, a local activist, points at a blackened stump in a clearing cut by burners. It is perhaps 400 years old, he says. The effect of burning trees spreads far. During the dry season, the forest is a refuge for amorous elephants who come in from the plains nearby to breed. The trees store water, which is useful in such a parched region. It not only keeps the Mara river flowing—a draw for the tourists who provide most of the county government’s revenue. It also allows the Masai people to graze their cows and grow crops. “You cannot separate the Masai Mara and this forest,” says Mr Naikada….
Nyakweri is hardly the only forest at risk. The Mau forest, Kenya’s largest, which lies farther north in the Rift Valley, has also been hit by illegal logging. Protests against charcoal traders (!) broke out earlier this year, after rivers that usually flow throughout the dry season started to run dry. In late February a trader’s car was reportedly burned in Mwingi, in central Kenya, by a group of youngsters who demanded to see the trader’s permits. At the end of February 2018 the government announced an emergency 90-day ban on all logging, driving up retail prices of charcoal by 500%, to as much as 5,000 shillings a bag in some cities.
The problems caused by the charcoal trade have spread beyond Kenya. In southern Somalia, al-Shabab, a jihadist group, funds itself partly through the taxes it levies on the sale of charcoal (sometimes with the help of Kenyan soldiers, who take bribes for allowing the shipments out of a Somali port that Kenya controls). The logging also adds to desertification, which, in turn, causes conflict across the Sahel, an arid belt below the Sahara. It forces nomadic herders to range farther south with their animals, where they often clash with farmers over the most fertile land.
In the power vacuum of the eastern Democratic Republic of Congo, rampant charcoal logging has destroyed huge swathes of Virunga National Park. That threatens the rare gorillas which tourists currently pay as much as $400 a day to view, even as it fuels the conflict.
In theory, charcoal burning need not be so destructive. In Kenya the burners are meant to get a licence. To do so, they have to show they are replacing the trees they are cutting down and that they are using modern kilns that convert the trees efficiently into fuel. But, admits Clement Ngoriareng, an official at the Kenya Forest Service (KFS), the rules are laxly enforced. Some suspect that powerful politicians stymie efforts to police burners.
