EU-Wide Ban on Bee-Harming Pesticides Likely After Major Review

The European Food Safety Authority (EFSA) concluded in a new assessment that "most uses" of three widely used neonicotinoids—imidacloprid, clothianidin and thiamethoxam—pose a risk to wild bees and honeybees, which play a crucial role in pollination across the globe.

The conclusion, based on analysis of more than 1,500 studies, will likely prompt a total ban on the pesticides from all fields across the European Union when the issue comes to a vote next month, the Guardian reported.


The EU already banned the pesticides on flowering crops in 2013. But the new report suggests the existing ban is insufficient, as using the chemicals in any outdoor setting can pose a risk to bees.

Thousands of studies have identified neonicotinoids as key contributors to declining pollinator populations. The chemicals have even been found to harm birds and aquatic invertebrates.

"The availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions," said Jose Tarazona, head of EFSA's pesticides unit.

"There is variability in the conclusions, due to factors such as the bee species, the intended use of the pesticide and the route of exposure. Some low risks have been identified, but overall the risk to the three types of bees we have assessed is confirmed."

German chemical giant Bayer makes imidacloprid and clothianidin, and Swiss agribusiness Syngenta makes thiamethoxam. The companies are challenging the restrictions in EU courts.

Bayer said it "fundamentally disagrees" with EFSA's analysis. And a Syngenta spokesman told the Guardian, "EFSA sadly continues to rely on a [bee risk guidance] document that is overly conservative, extremely impractical and would lead to a ban of most if not all insecticides, including organic products."

But environmental groups celebrated the new EFSA report.

"The evidence is overwhelming that bees, and the crops and plants they pollinate, are at dire risk from neonicotinoid pesticides," Franziska Achterberg, Greenpeace EU food policy adviser, said. "National governments must stop dithering and back the proposed EU neonicotinoid ban as the first step to prevent the catastrophic collapse of bee populations."

India Suffers 'Worst Water Crisis in Its History'

India is facing its "worst-ever" water crisis, according to a report from a government think tank issued last week.

Around 200,000 Indians die each year due to lack of water access, the report finds, and demand will be twice as much as supply by 2030.

Urban Gardening 101: How to Deal With Contaminated Soil

By Brian Barth

Urban soils are particularly prone to contamination. Fifty years ago, your yard could have belonged to a farmer, who, perhaps not knowing any better, disposed of old bottles of anti-freeze or contaminated diesel in a hole out behind the tractor garage. Or perhaps the remains of a fallen down outbuilding, long ago coated in lead-based paint, was buried on your property buy a lazy contractor when your subdivision was built.

Sea Level Rise Could Put 2.4 MIllion U.S. Coastal Homes at Risk

More than 300,000 U.S. coastal homes could be uninhabitable due to sea level rise by 2045 if no meaningful action is taken to combat climate change, a Union of Concerned Scientists (UCS) study published Monday found.

The study, Underwater: Rising Seas, Chronic Floods and the Implications for U.S. Coastal Real Estate, set out to calculate how many coastal properties in the lower 48 states would suffer from "chronic inundation," non-storm flooding that occurs 26 times a year or more, under different climate change scenarios.

U.S. Sees Steady Solar Growth Despite Trump, But China Slashes Subsidies

By Andy Rowell

Donald Trump can't stop the sun from shining. Despite the climate denier's pro-fossil fuel agenda, and despite his tariffs on imported solar panels, the U.S. still installed more solar than any other source of energy in the first quarter of the year.

The amount of solar power installed in the U.S. climbed 13 percent in the first quarter, according to the trade body, the Solar Energy Industries Association (SEIA).

How a Minor Change to EPA Rules Could Slash Environmental Protection

By Joseph Aldy

Since the Reagan administration, federal agencies have been required to produce cost-benefit analyses of their major regulations. These assessments are designed to ensure that regulators are pursuing actions that make society better off.

In my experience working on the White House economic team in the Clinton and Obama administrations, I found cost-benefit analysis provides a solid foundation for understanding the impacts of regulatory proposals. It also generates thoughtful discussion of ways to design rules to maximize net benefits to the public.
