During the seventeen years she worked in the US Fish and Wildlife Service, Rachel Carson learned about the problems of pesticides. Undaunted by the chemical companies' hostility and by the public's high enthusiasm for pesticides, she wrote a book called Silent Spring, which caused a major shift in public consciousness about the environment.
In 1958 Carson found out about an article that the Reader's Digest was about to
publish. It was dealing with the benefits of aerial spraying. She wrote to DeWitt Wallace, the magazine's editor-in-chief, telling him of the danger, both to wildlife and to public health, in the projects for insect control by poisons, especially when distributed by airplanes * (Graham, p. 17). By documenting her case, Carson was able to convince Wallace not to publish the article.
