Neonicotinoids: The New DDT?

(Earth Focus: Episode 69) Neonicotinoids are the most widely used insecticides in the world. But they've been linked to the decline of honeybees, which pollinate many food crops.

They kill off insects that many birds, amphibians, and reptiles rely on for food. "We are witnessing a threat to the productivity of our natural and farmed environment equivalent to that posed by organophosphates or DDT," says Dr. Jean Marc Bonmatin, the lead author of an October 2014 report by the international Task Force on Systemic Pesticides.
