An extended conversation with Patti Goldman of Earthjustice about the Environment Protection Agency’s decision not to ban the powerful pesticide chlorpyrifos. Although no longer available for household use, chlorpyrifos is still used by farmers on more than 50 fruit, nuts, cereal and vegetable crops. The EPA’s own research shows that it can cause brain damage in children even at small doses. “It’s an outdated pesticide that hits anything with a nervous system,” says Goldman.
