Carson was formerly with the U.S. Fish and Wildlife Department. After the publication of Silent Spring, President Kennedy ordered a review of Government pesticide programs, but nothing was really done until the EPA was established in 1970. Two years later, it banned DDT, as well as other "elixirs of death" written about by Carson, including chlordane, dieldrin, aldrin, and heptachlor. The use of pesticides rose, but it was of the relatively safer kind that dissipated more quickly.
