The First Environmentalist: Rachel Carson
Rachel Louise Carson received her degrees in marine biology from the Pennsylvania College for Women and in zoology from the Johns Hopkins University. As Carson's career as a scientific writer progressed, she became interested in the effects of artificial chemicals on the natural environment. Through her published research, she was the first to direct public attention to the environmental damage caused by the indiscriminate use of pesticides in agriculture. She is thus regarded as the public figure who launched the environmentalist movement.
Wedded to her extensive academic training in biology, Carson's talent for expressive writing positioned her ideally to bring scientific findings about ecology to a mass audience. She published a famous trilogy about the delicate and complex ecology of the sea, beginning with Under the Sea-Wind. Under the Sea-Wind was only a moderate commercial success, but it, along with Carson's writings for the United States Fish and Wildlife Service, set the stage for her second volume, published ten years after the first. The Sea Around Us made Rachel Carson a household name. In it, Carson examined more explicitly than before the effects of human action on the creatures of the ocean.
She began to examine data on the effects of agricultural pesticides. Carson's research convinced her that high exposure to pesticides such as DDT threatened not only beneficial insects and birds but also people. She put her conclusions in a landmark fourth scientific volume, Silent Spring. fourth scientific volume, Silent Spring, which hypothesized about an ecosystem in which the calling of birds had been silenced by poison in soil and groundwater.
Carson alleged that the regulations governing use of these chemicals were inadequate, though her positions were not as extreme as they are sometimes now characterized. She did not support the outright banning of pesticides. Rather, she objected to "indiscriminate" use, which is to say, use without any thought for caution and moderation. Eventually, Carson's views were taken seriously at the highest levels of government.
[I] Although Carson's fame meant that she was in demand as a public speaker, she much preferred the solitude of research and writing. [II] She employed assistants but frequently did even tedious archival research herself to avoid wasting time reviewing material with which she was already familiar. [III] Her best-selling work, it also remains a staple of high school and college science classes. [IV] Indeed, more than one major publication has deemed Carson one of the most influential figures of the twentieth century.
