97% of Endangered Species Threatened by Two Common Pesticides

The U.S. Environmental Protection Agency (EPA) released its first rigorous nationwide analysis Wednesday of the effects of pesticides on endangered species, finding that 97 percent of the more than 1,800 animals and plants protected under the Endangered Species Act are likely to be harmed by malathion and chlorpyrifos, two commonly used pesticides. Another 78 percent are likely to be hurt by the pesticide diazinon. The results released Wednesday are the final biological evaluations the EPA completed as part of its examination of the impacts of these pesticides on endangered species.

"We're now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants," said Nathan Donley, senior scientist at the Center for Biological Diversity. "The next step will hopefully be some commonsense measures to help protect them along with our water supplies and public health."

The three pesticides are all organophosphates, a dangerous old class of insecticides found in 87 percent of human umbilical-cord samples and widely used on crops such as corn, watermelon and wheat. Chlorpyrifos is currently under consideration to be banned for use on food crops in the U.S. The World Health Organization last year announced that malathion and diazinon are probable carcinogens.

"When it comes to pesticides, it's always best to look before you leap, to understand the risks to people and wildlife before they're put into use," said Donley. "The EPA is providing a reasonable assessment of those risks, many of which can be avoided by reducing our reliance on the most toxic, dangerous old pesticides in areas with sensitive wildlife."

Following these final evaluations from the EPA, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service will issue biological opinions to identify mitigation measures and changes to pesticide use to help ensure that these pesticides will no longer potentially harm any endangered species in the U.S. when used on agricultural crops. As part of a legal settlement with the Center for Biological Diversity, these biological opinions are on deadline to be completed by December 2017.

Large Swath of Texas Oil Patch Rapidly Sinking and Uplifting, Study Finds

West Texas is already home to two giant sinkholes near the town of Wink caused by intensive oil and gas operations. Now, according to an unprecedented study, the "Wink Sinks" might not remain the last in the region.

Geophysicists at Southern Methodist University (SMU) in Dallas have found rapid rates of ground movement at various locations across a 4,000-square-mile swath around the two sinkholes. This area is known for processing extractions from the oil-rich Permian Basin.

Study Shows Some Pesticides More Bee-Safe Than Others, But Are Any Pesticides Eco-Friendly?

A study published Thursday in Current Biology is being hailed in a University of Exeter press release as a major "breakthrough" in developing bee-friendly insecticides. But some environmentalists think the research is asking the wrong questions to begin with.

More Than 140 Whales Dead After Mass Stranding in Western Australia

More than 150 short-finned pilot whales stranded en masse at Hamelin Bay on the west coast of Australia early Friday morning.

Most of the whales did not survive after beaching themselves, according to Jeremy Chick, incident controller at Western Australia's Parks & Wildlife Service.

Tech Giant Microsoft Signs Largest Corporate Solar Agreement in the U.S.

By Katrine Tilgaard Petersen

Microsoft has announced the single largest corporate purchase of solar power ever seen in the U.S., signing an agreement with sPower to add 315 MW of electricity via two solar projects in Virginia.

Microsoft has been powered by 100 percent renewable electricity since 2014. In 2015, the tech giant joined RE100, a global corporate leadership initiative by The Climate Group in partnership with CDP, now bringing together 130 ambitious companies committed to sourcing entirely renewable power.

The New Government Omnibus Spending Bill Shows That Science Advocacy Matters

By Yogin Kothari

After a long wait, late Wednesday night, Congress posted a spending agreement for the rest of the 2018 fiscal year. For the most part, we achieved significant victories, especially given the challenging political environment, in repelling proposals that would have directly undermined the role of science in public health and environmental policymaking.
