Can’t Eat This! MicroPlastics that Carry Bacteria

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.

Nurdles on bathing beach

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.

A Swamp of Oil Pollution: Ogoniland

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..

How to Save the Rhino? Torture and Kill Civilians

In national parks across Asia and Africa, the beloved nonprofit WWF  with the cuddly panda logo funds, equips, and works directly with paramilitary forces that have been accused of beating, torturing, sexually assaulting, and murdering scores of people…WWF has provided high-tech enforcement equipment, cash, and weapons to forces implicated in atrocities against indigenous communities…Villagers have been whipped with belts, attacked with machetes, beaten unconscious with bamboo sticks, sexually assaulted, shot, and murdered by WWF-supported anti-poaching units, according to reports and document

 WWF has provided paramilitary forces with salaries, training, and supplies — including knives, night vision binoculars, riot gear, and batons — and funded raids on villages…The charity has operated like a global spymaster, organizing, financing, and running dangerous and secretive networks of informants motivated by “fear” and “revenge,” including within indigenous communities, to provide park officials with intelligence — all while publicly denying working with informants.

The charity funnels large sums of cash to its field offices in the developing world where staff work alongside national governments — including brutal dictatorships — to help maintain and police vast national parks that shelter endangered species. But many parks are magnets for poachers, and WWF expends much of its energy — and money — in a global battle against the organized criminal gangs that prey on the endangered species the charity was founded to protect.  It’s a crusade that WWF refers to in the hardened terms of war. Public statements speak of “boots on the ground,” partnerships with “elite military forces,” the creation of a “Jungle Brigade,” and the deployment of “conservation drones.”  WWF is not alone in its embrace of militarization: Other conservation charities have enlisted in the war on poaching in growing numbers over the past decade, recruiting veterans from the wars in Afghanistan and Iraq to teach forest rangers counterinsurgency techniques

The enemy is real, and dangerous. Poaching is a billion-dollar industry that terrorizes animals and threatens some species’ very existence. Poachers take advantage of regions ravaged by poverty and violence. And the work of forest rangers is indeed perilous: By one 2018 estimate, poachers killed nearly 50 rangers around the world in the previous year. But like any conflict, WWF’s war on poaching has civilian casualties.

Indigenous people living near one park in southeast Cameroon described a litany of horrors incuding dead-of-night break-ins by men wielding machetes, rifle butt bludgeonings, burn torture involving chilis ground into paste, and homes and camps torched to the ground. Their tormentors in these accounts were not poachers, but the park officials who police them. Although governments employ the rangers, they often rely on WWF to bankroll their work.  …Documents reveal WWF’s own staffers on the ground are often deeply entwined with the rangers’ work — coordinating their operations, jointly directing their raids and patrols alongside government officials, and turning a blind eye to their misdeeds.

Iindigenous groups — both small-fry hunters and innocent bystanders — say they suffer at the hands of the rangers.  Nepal’s park officials were given this free rein decades ago, shortly after WWF first arrived in Chitwan in 1967 to launch a rhinoceros conservation project in a lush lowland forest at the foot of the Himalayas. To clear the way, tens of thousands of indigenous people were evicted from their homes and moved to areas outside the park’s boundaries..

The park’s creation radically changed their way of life: Now they must scrape together money to buy tin for their roofs, pay hospital bills, and farm new crops. They also live in fear of the park’s wild animals, which, while rising in number thanks to anti-poaching efforts, have destroyed crops and mauled people to death.  Rhinoceros horns can sell for hundreds of thousands of dollars on the black market. Professional poachers offer a tiny portion to locals who assist them, which can be hard for impoverished residents of villages to turn down.

Chitwan’s forest rangers work alongside over 1,000 soldiers from the park’s army battalion. Nepalese law gives them special power to investigate wildlife-related crimes, make arrests without a warrant, and retain immunity in cases where an officer has “no alternative” but to shoot the offender, even if the suspect dies….. Indigenous groups living near Chitwan have long detailed a host of abuses by these forces. Villagers have reported beatings, torture, sexual assaults, and killings by the park’s guards. They’ve accused park officials of confiscating their firewood and vegetables, and forcing them into unpaid labor.

WWF’s work with violent partners spans the globe. In Central Africa, internal documents show the charity’s close involvement in military-style operations with both a repressive dictatorship and a notoriously fierce army. …The park’s management plan says WWF will help organize raids, known as “coup de poings,” on local villages suspected of harboring poachers. A confidential internal report found that such missions, frequently conducted in the dead of night with the help of police units, were often violent.

Who is Afraid of Bats?

More than 50,000 of the fruit bats are thought to have been killed in Mauritius since 2015, in an attempt to protect fruit in orchards.  The bats – also known as flying foxes – are resorting to eating in orchards to survive because only 5 per cent of Mauritius’s native forests remain, animal experts warned.  Fruit bats are vital for biodiversity as they pollinate flowers and scatter seeds, enabling trees and plants to grow and spread, according to conservationists.  But populations of the flying foxes have fallen by more than 50 per cent in four years, said Vincent Florens, an ecologist at the University of Mauritius. Some believe fewer than 30,000 now remain.

The first cull, in 2015, killed 30,000, and in a second cull, the following year, 7,380 were targeted.  The latest cull involved 13,000.  Prof Florens said he believed the number killed is much higher than the 50,300 government figure.  “The culls took place late in the year, when many mothers were pregnant or had babies,” he told National Geographic. “You shoot one bat and basically kill two.” Others were likely to have been injured and died later, he said.

Scientists are supporting a lawsuit against the government on grounds of animal welfare violations to prevent any more culls…Mahen Seeruttun, Mauritius’s minister of agro-industry and food security, told FDI Spotlight: “We have a large population of bats who will eat fruit crops.

Olkiluoto 3 Nuclear Plant is Ready: 2005-2020

Finland’s Radiation and Nuclear Safety Authority (Stuk) yesterday informed the government it sees no reason why an operating licence for the first-of-a-kind nuclear plant EPR at Olkiluoto 3 should not be granted to utility Teollisuuden Voima Oyj (TVO).]…The Areva-Siemens consortium began construction of Olkiluoto 3 – the first-of-a-kind EPR – in 2005 under a turnkey contract signed with TVO in late 2003. Completion of the reactor was originally scheduled for 2009, but the project has suffered various delays and setbacks. Under the latest schedule, fuel will now be loaded into the reactor core in June 2019, with grid connection to take place in October 2019, and the start of regular electricity generation scheduled for January 2020.

In December 2018, unit 1 of the Taishan plant in China’s Guangdong province became the first EPR to enter commercial operation. Taishan 2 is scheduled to begin commercial operation in 2019. The loading of fuel into the core of the Flamanville EPR in France is expected towards the end of this year. Two EPR units are also under construction at the Hinkley Point C project in Somerset, UK.

The Micro-Plastics Menance: Oceans

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.

Cleaning Up the US Nuclear Weapons Complex

A report from the National Academies of Sciences published in March 2019 recommends changes in the way that the U.S. Department of Energy manages science and technology (S&T) development in order to accelerate the cleanup of radioactive waste and contaminated soil, groundwater, and facilities at U.S. nuclear weapons sites.

A portion of DOE’s technology development should focus on breakthrough solutions and technologies that can substantially reduce schedules, risks, and uncertainties in the cleanup, says Independent Assessment of Science and Technology for the Department of Energy’s Defense Environmental Cleanup Program. This effort should be managed by ARPA-E, a DOE division that has a record of investing in innovative solutions for complex technical challenges; it would require substantial new funding…DOE’s Office of Environmental Management (DOE-EM) is responsible for cleaning up 107 sites in 31 states and one territory that were used for nuclear weapons development, testing, and related activities during the Manhattan Project and Cold War. The cleanup program began in 1989 and has, over the past three decades, cleaned up 91 sites at a cost of about $170 billion. DOE-EM projects that it will spend at least another 50 years and $377 billion to complete its cleanup of the 16 remaining sites.

The new report says that these time and cost estimates are highly uncertain – and probably low – because of significant remaining technical challenges and uncertainties, and also because additional sites and facilities may be added to the cleanup program in the future. ..Currently, DOE-EM’s management of S&T development is ad hoc and uncoordinated, the report says. Most DOE-EM-related S&T development activities are focused on individual sites, are driven and managed by contractors, and have a short-term emphasis on addressing technical challenges in existing cleanup projects…The successful cleanup of the large, complex Rocky Flats site near Denver showed that technology development and deployment can have major impacts in accelerating schedules and reducing costs, the report notes. The remaining cleanup sites – which include large, complex sites such as Hanford in Washington state, the Savannah River Site in South Carolina, and the Oak Ridge Reservation in Tennessee – provide an opportunity for S&T to have similar impacts.

The report identifies seven examples of technologies and alternative approaches that could substantially reduce costs and speed cleanup schedules – these include changes in waste chemistry and nuclear properties to facilitate treatment and disposal, and changes in human involvement in cleanup activities to increase efficiencies and reduce worker risks.
