Are Agriculture's Most Popular Insecticides Killing Our Bees?
Environmentalists and beekeepers are calling on the government to ban some of the country's most widely used insect-killing chemicals.
The pesticides, called neonicotinoids, became popular among farmers during the 1990s. They're used to coat the seeds of many agricultural crops, including the biggest crop of all: corn. Neonics, as they're called, protect those crops from insect pests.
But they may also be killing bees.
