The Trump administration has rescinded an Obama-era ban on the use of pesticides linked to declining bee populations and the cultivation of genetically modified crops in dozens of national wildlife refuges where farming is permitted.

Environmentalists, who had sued to bring about the 2-year-old ban, said Friday that lifting the restriction poses a grave threat to pollinating insects and other sensitive creatures relying on toxic-free habitats afforded by wildlife refuges.

"Industrial agriculture has no place on refuges dedicated to wildlife conservation and protection of some of the most vital and vulnerable species," said Jenny Keating, federal lands policy analyst for the group Defenders of Wildlife.
