This video segment adapted from American Experience: "Rachel Carson’s Silent Spring" tells the story of how biologist Rachel Carson was driven to write Silent Spring, a book that questioned the safety of pesticide use in the United States. The most famous pesticide at the time was DDT, a chemical that had saved millions of lives in World War II from insect-borne disease and was thought to be safe. But Carson found evidence that DDT was poisoning birds, and represented a real threat to humans as well. The video states that Carson was not against the use of chemicals altogether; rather, she thought the chemical industry was pushing their overuse for its economic gain, at the expense of health and the environment.
Rachel Carson is widely credited with having started the environmental movement in the United States by publishing a book called Silent Spring. Four years in the making before its publication in 1962, Silent Spring was researched almost entirely by Carson. In the main part of the book, she documented the effects pesticides had on all kinds of life. She concluded that certain chemicals released into the environment, including the pesticide DDT, were harming birds and animals. They were also contaminating the entire world’s food supply.
Before writing Silent Spring, Carson was a marine biologist with the U.S. Fish and Wildlife Service and had already authored two highly acclaimed nature books. While still with the agency, she had observed the effects of DDT on fish and other aquatic life. These species are generally first among all living things to exhibit abnormalities caused by harmful factors in the environment. The combination of scientific expertise and a talent for writing helped her not only to gauge the credibility of the data she uncovered, but also to translate what might otherwise be dull scientific facts into prose that would resonate with the general public.
Carson was praised for having taken a conservative approach with the book. She was careful to limit the examples she used to those she could verify and defend. As it turned out, much of the data Carson presented in Silent Spring had already appeared in various scientific publications; she had simply synthesized its reporting. Carson expressed many times that she was not opposed to chemical sprays for the purpose of controlling pests. Rather, it was their "indiscriminate use" at a time when their wider effects were not well understood that she rallied against.
The chemical industry that made the pesticides disputed Carson and Silent Spring. They claimed her work was full of distorted facts and unsupported by scientific evidence. But Carson had carefully documented her research with more than 50 pages of notes, which included a list of experts who had read and approved the manuscript and would later support her. When President John F. Kennedy’s Science Advisory Committee examined the issues the book raised, it released a report that vindicated Carson’s findings. As a result, DDT came under much closer government scrutiny and was eventually banned in 1972.
Before Silent Spring was published, the overuse of pesticides was not high in the minds of U.S. citizens. But Carson managed to define threats to public health that were too frightening to ignore. As the need to regulate industry and agricultural practices in order to protect the environment became widely accepted, the environmental movement was born.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
