Carson warned about the overuse of pesticides like DDT (short for dichlorodiphenyltrichloroethane). These were overused in the agricultural industry in an attempt to control crop pests. This pesticide compound would be washed into streams and rivers and Carson warned that it was moving up the food chain, and entire ecosystems were threatened because it was dangerous for birds and fish and humans eating these animal and plant products too. Carson's was a successful science writer and scientist herself. Her argument reached far and wide after she published the Silent Spring in 1962. It is credited with the nationwide ban on the use of DDT and the creation of the Environmental Protection Agency.
