The U.S. Environmental Protection Agency has determined that the endocrine-disrupting pesticide atrazine and cancer-linked pesticide glyphosate are each likely to harm more than 1,000 of the nation’s most endangered plants and animals.

The finalized evaluations found that use of the herbicide glyphosate is likely causing harm to 1,676 of the plants and animals protected under the Endangered Species Act. Atrazine is likely harming 1,013 protected species.

“It’s no surprise that these chemical poisons are causing severe harm to imperiled wildlife since U.S. use exceeds 70 million pounds of atrazine and 300 million pounds of glyphosate every year,” said Nathan Donley, environmental health science director at the Center for Biological Diversity. “It’s long past time for atrazine to be banned, and the EPA needs to crack down on the reckless overuse of glyphosate. Without real conservation action, these pesticides will continue to push our most endangered wildlife closer to extinction.”
