This collection of readings has been put together by Dunlap (history, Texas A&M U.) in order to provide a picture of how expanding knowledge about the effects of the insecticide DDT (Dichloro-Diphenyl-Trichloroethane) on wildlife shaped American attitudes toward it and then affected policy. The readings include excerpts from scientific articles, newspaper articles and editorials, government reports, and a small portion of Rachel Carson's influential Silent Spring.
