Silent Spring is an environmental science book written by Rachel Carson and published by Houghton Mifflin on September 27, 1962. The book documented the detrimental effects on the environment—particularly on birds—of the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation and public officials of accepting industry claims unquestioningly.
In the late 1950s, Carson turned her attention to conservation, especially environmental problems that she believed were caused by synthetic pesticides. The result was Silent Spring (1962), which brought environmental concerns to the American public. Silent Spring was met with fierce opposition by chemical companies, but it spurred a reversal in national pesticide policy, led to a nationwide ban on DDT for agricultural uses, and inspired an environmental movement that led to the creation of the U.S. Environmental Protection Agency.
Research and writing
In the mid-1940s, Carson became concerned about the use of synthetic pesticides, many of which had been developed through the military funding of science since World War II. The USDA's 1957 fire ant eradication program, which involved aerial spraying of DDT and other pesticides mixed with fuel oil and included the spraying of private land, prompted Carson to devote her research, and her next book, to pesticides and environmental poisons. Landowners in Long Island filed a suit to have the spraying stopped, and many in affected regions followed the case closely. Though the suit was lost, the Supreme Court granted petitioners the right to gain injunctions against potential environmental damage in the future, laying the basis for later environmental actions.
The impetus for Silent Spring was a letter written in January 1958 by Carson's friend, Olga Owens Huckins, to The Boston Herald, describing the death of birds around her property resulting from the aerial spraying of DDT to kill mosquitoes, a copy of which Huckins sent to Carson. Carson later wrote that this letter prompted her to study the environmental problems caused by chemical pesticides.
The Washington, D.C. chapter of the Audubon Society actively opposed chemical spraying programs and recruited Carson to help publicize the U.S. government's spraying practices and related research. Carson began the four-year project of Silent Spring by gathering examples of environmental damage attributed to DDT. She tried to enlist essayist E. B. White and a number of journalists and scientists to her cause. By 1958, Carson had arranged a book deal, with plans to co-write with Newsweek science journalist Edwin Diamond. However, when The New Yorker commissioned a long and well-paid article on the topic from Carson, she began considering writing more than the introduction and conclusion as planned; soon it became a solo project. Diamond would later write one of the harshest critiques of Silent Spring.
As her research progressed, Carson found a sizable community of scientists who were documenting the physiological and environmental effects of pesticides. She took advantage of her personal connections with many government scientists, who supplied her with confidential information on the subject. From reading the scientific literature and interviewing scientists, Carson found two scientific camps; those who dismissed the possible danger of pesticide spraying barring conclusive proof and those who were open to the possibility of harm and were willing to consider alternative methods, such as biological pest control.
By 1959, the USDA's Agricultural Research Service responded to the criticism by Carson and others with a public service film, Fire Ants on Trial; Carson called it "flagrant propaganda" that ignored the dangers that spraying pesticides posed to humans and wildlife. That spring, Carson wrote a letter, published in The Washington Post, that attributed the recent decline in bird populations—in her words, the "silencing of birds"—to pesticide overuse. The same year, the 1957, 1958, and 1959 crops of U.S. cranberries were found to contain high levels of the herbicide aminotriazole and the sale of all cranberry products was halted. Carson attended the ensuing FDA hearings on revising pesticide regulations; she was discouraged by the aggressive tactics of the chemical industry representatives, which included expert testimony that was firmly contradicted by the bulk of the scientific literature she had been studying. She also wondered about the possible "financial inducements behind certain pesticide programs".
Research at the Library of Medicine of the National Institutes of Health brought Carson into contact with medical researchers investigating the gamut of cancer-causing chemicals. Of particular significance was the work of National Cancer Institute researcher and founding director of the environmental cancer section Wilhelm Hueper, who classified many pesticides as carcinogens. Carson and her research assistant Jeanne Davis, with the help of NIH librarian Dorothy Algire, found evidence to support the pesticide-cancer connection; to Carson the evidence for the toxicity of a wide array of synthetic pesticides was clear-cut, though such conclusions were very controversial beyond the small community of scientists studying pesticide carcinogenesis.
By 1960, Carson had sufficient research material and the writing was progressing rapidly. She had investigated hundreds of individual incidents of pesticide exposure and the resulting human sickness and ecological damage. In January 1960, she suffered an illness which kept her bedridden for weeks, delaying the book. As she was nearing full recovery in March, she discovered cysts in her left breast, requiring a mastectomy. By December that year, Carson discovered that she had breast cancer, which had metastasized. Her research was also delayed by revision work for a new edition of The Sea Around Us, and by a collaborative photo essay with Erich Hartmann. Most of the research and writing was done by the fall of 1960, except for a discussion of recent research on biological controls and investigations of some new pesticides. However, further health troubles delayed the final revisions in 1961 and early 1962.
Its title was inspired by a poem by John Keats, "La Belle Dame sans Merci", which contained the lines "The sedge is wither'd from the lake, And no birds sing." "Silent Spring" was initially suggested as a title for the chapter on birds. By August 1961, Carson agreed to the suggestion of her literary agent Marie Rodell: Silent Spring would be a metaphorical title for the entire book—suggesting a bleak future for the whole natural world—rather than a literal chapter title about the absence of birdsong. With Carson's approval, editor Paul Brooks at Houghton Mifflin arranged for illustrations by Louis and Lois Darling, who also designed the cover. The final writing was the first chapter, "A Fable for Tomorrow", which was intended to provide a gentle introduction to a serious topic. By mid-1962, Brooks and Carson had largely finished the editing and were planning to promote the book by sending the manuscript to select individuals for final suggestions. In Silent Spring, Carson relied on evidence from two New York state organic farmers, Marjorie Spock and Mary Richards, and that of biodynamic farming advocate Ehrenfried Pfeiffer in developing her case against DDT.
The overriding theme of Silent Spring is the powerful—and often negative—effect humans have on the natural world. Carson's main argument is that pesticides have detrimental effects on the environment; she says these are more properly termed "biocides" because their effects are rarely limited to the target pests. DDT is a prime example, but other synthetic pesticides—many of which are subject to bioaccumulation—are scrutinized. Carson accuses the chemical industry of intentionally spreading disinformation and public officials of accepting industry claims uncritically. Most of the book is devoted to pesticides' effects on natural ecosystems, but four chapters detail cases of human pesticide poisoning, cancer, and other illnesses attributed to pesticides. About DDT and cancer, Carson says only:
In laboratory tests on animal subjects, DDT has produced suspicious liver tumors. Scientists of the Food and Drug Administration who reported the discovery of these tumors were uncertain how to classify them, but felt there was some "justification for considering them low grade hepatic cell carcinomas." Dr. Hueper [author of Occupational Tumors and Allied Diseases] now gives DDT the definite rating of a "chemical carcinogen."
Carson predicts increased consequences in the future, especially since targeted pests may develop resistance to pesticides and weakened ecosystems fall prey to unanticipated invasive species. The book closes with a call for a biotic approach to pest control as an alternative to chemical pesticides.
Carson never called for an outright ban on DDT. She said in Silent Spring that even if DDT and other insecticides had no environmental side effects, their indiscriminate overuse was counterproductive because it would create insect resistance to pesticides, making them useless in eliminating the target insect populations:
No responsible person contends that insect-borne disease should be ignored. The question that has now urgently presented itself is whether it is either wise or responsible to attack the problem by methods that are rapidly making it worse. The world has heard much of the triumphant war against disease through the control of insect vectors of infection, but it has heard little of the other side of the story—the defeats, the short-lived triumphs that now strongly support the alarming view that the insect enemy has been made actually stronger by our efforts. Even worse, we may have destroyed our very means of fighting.
Carson also said that "Malaria programmes are threatened by resistance among mosquitoes", and quoted the advice given by the director of Holland's Plant Protection Service: "Practical advice should be 'Spray as little as you possibly can' rather than 'Spray to the limit of your capacity' ... Pressure on the pest population should always be as slight as possible."
Promotion and reception
Carson and the others involved with publication of Silent Spring expected fierce criticism and were concerned about the possibility of being sued for libel. Carson was undergoing radiation therapy for her cancer and expected to have little energy to defend her work and respond to critics. In preparation for the anticipated attacks, Carson and her agent attempted to amass prominent supporters before the book's release.
Most of the book's scientific chapters were reviewed by scientists with relevant expertise, among whom Carson found strong support. Carson attended the White House Conference on Conservation in May 1962; Houghton Mifflin distributed proof copies of Silent Spring to many of the delegates and promoted the upcoming serialization in The New Yorker. Carson also sent a proof copy to Supreme Court Associate Justice William O. Douglas, a long-time environmental advocate who had argued against the court's rejection of the Long Island pesticide spraying case and had provided Carson with some of the material included in her chapter on herbicides.
Though Silent Spring had generated a fairly high level of interest based on pre-publication promotion, this became more intense with its serialization, which began in the June 16, 1962, issue. This brought the book to the attention of the chemical industry and its lobbyists, as well as the American public. Around that time, Carson learned that Silent Spring had been selected as the Book-of-the-Month for October; she said this would "carry it to farms and hamlets all over that country that don't know what a bookstore looks like—much less The New Yorker." Other publicity included a positive editorial in The New York Times and excerpts of the serialized version were published in Audubon Magazine. There was another round of publicity in July and August as chemical companies responded. The story of the birth defect-causing drug thalidomide had broken just before the book's publication, inviting comparisons between Carson and Frances Oldham Kelsey, the Food and Drug Administration reviewer who had blocked the drug's sale in the United States.
In the weeks before the September 27, 1962, publication, there was strong opposition to Silent Spring from the chemical industry. DuPont, a major manufacturer of DDT and 2,4-D, and Velsicol Chemical Company, the only manufacturer of chlordane and heptachlor, were among the first to respond. DuPont compiled an extensive report on the book's press coverage and estimated impact on public opinion. Velsicol threatened legal action against Houghton Mifflin, and The New Yorker and Audubon Magazine unless their planned Silent Spring features were canceled. Chemical industry representatives and lobbyists lodged a range of non-specific complaints, some anonymously. Chemical companies and associated organizations produced brochures and articles promoting and defending pesticide use. However, Carson's and the publishers' lawyers were confident in the vetting process Silent Spring had undergone. The magazine and book publications proceeded as planned, as did the large Book-of-the-Month printing, which included a pamphlet by William O. Douglas endorsing the book.
American Cyanamid biochemist Robert White-Stevens and former Cyanamid chemist Thomas Jukes were among the most aggressive critics, especially of Carson's analysis of DDT. According to White-Stevens, "If man were to follow the teachings of Miss Carson, we would return to the Dark Ages, and the insects and diseases and vermin would once again inherit the earth". Others attacked Carson's personal character and scientific credentials, her training being in marine biology rather than biochemistry. White-Stevens called her "a fanatic defender of the cult of the balance of nature", while former U.S. Secretary of Agriculture Ezra Taft Benson in a letter to former President Dwight D. Eisenhower reportedly said that because she was unmarried despite being physically attractive, she was "probably a Communist".
Many critics repeatedly said Carson was calling for the elimination of all pesticides, but had made it clear she was not advocating this but was instead encouraging responsible and carefully managed use with an awareness of the chemicals' impact on ecosystems. She concludes her section on DDT in Silent Spring with advice for spraying as little as possible to limit the development of resistance. Mark Hamilton Lytle writes, Carson "quite self-consciously decided to write a book calling into question the paradigm of scientific progress that defined postwar American culture".
The academic community—including prominent defenders such as H. J. Muller, Loren Eisley, Clarence Cottam and Frank Egler—mostly backed the book's scientific claims and public opinion backed Carson's text. The chemical industry campaign was counterproductive because the controversy increased public awareness of the potential dangers of pesticides. Pesticide use became a major public issue after a CBS Reports television special, "The Silent Spring of Rachel Carson", which was broadcast on April 3, 1963. The program included segments of Carson reading from Silent Spring and interviews with other experts, mostly critics including White-Stevens. According to biographer Linda Lear, "in juxtaposition to the wild-eyed, loud-voiced Dr. Robert White-Stevens in white lab coat, Carson appeared anything but the hysterical alarmist that her critics contended". Reactions from the estimated audience of ten to fifteen million were overwhelmingly positive and the program spurred a congressional review of pesticide hazards and the public release of a pesticide report by the President's Science Advisory Committee. Within a year publication, attacks on the book and on Carson had lost momentum.
In one of her last public appearances, Carson testified before President John F. Kennedy's Science Advisory Committee, which issued its report on May 15, 1963, largely backing Carson's scientific claims. Following the report's release, Carson also testified before a U.S. Senate subcommittee to make policy recommendations. Though Carson received hundreds of other speaking invitations, she was unable to accept most of them because her health was steadily declining, with only brief periods of remission. She spoke as much as she could, and appeared on The Today Show and gave speeches at several dinners held in her honor. In late 1963, she received a flurry of awards and honors: the Audubon Medal from the National Audubon Society, the Cullum Medal from the American Geographical Society, and induction into the American Academy of Arts and Letters.
Grassroots environmentalism and the EPA
Carson's work had a powerful impact on the environmental movement. Silent Spring became a rallying point for the new social movement in the 1960s. According to environmental engineer and Carson scholar H. Patricia Hynes, "Silent Spring altered the balance of power in the world. No one since would be able to sell pollution as the necessary underside of progress so easily or uncritically." Carson's work and the activism it inspired are partly responsible for the deep ecology movement and the strength of the grassroots environmental movement since the 1960s. It also influential on the rise of ecofeminism and on many feminist scientists. Carson's most direct legacy in the environmental movement was the campaign to ban the use of DDT in the United States, and related efforts to ban or limit its use throughout the world. The 1967 formation of the Environmental Defense Fund was the first major milestone in the campaign against DDT. The organization brought lawsuits against the government to "establish a citizen's right to a clean environment", and the arguments against DDT largely mirrored Carson's. By 1972, the Environmental Defense Fund and other activist groups had succeeded in securing a phase-out of DDT use in the United States, except in emergency cases.
The creation of the Environmental Protection Agency by the Nixon Administration in 1970 addressed another concern that Carson had written about. Until then, the USDA was responsible both for regulating pesticides and promoting the concerns of the agriculture industry; Carson saw this as a conflict of interest, since the agency was not responsible for effects on wildlife or other environmental concerns beyond farm policy. Fifteen years after its creation, one journalist described the EPA as "the extended shadow of Silent Spring". Much of the agency's early work, such as enforcement of the 1972 Federal Insecticide, Fungicide, and Rodenticide Act, was directly related to Carson's work. History professor Gary Kroll wroted, "Rachel Carson's Silent Spring played a large role in articulating ecology as a 'subversive subject'—as a perspective that cuts against the grain of materialism, scientism, and the technologically engineered control of nature."
In the 1980s, the policies of the Reagan Administration emphasized economic growth and removed many of the environmental policies adopted in response to Carson's work. Former Vice President of the United States and environmentalist Al Gore wrote an introduction to the 1992 edition of Silent Spring. He wrote: "Silent Spring had a profound impact ... Indeed, Rachel Carson was one of the reasons that I became so conscious of the environment and so involved with environmental issues ... [she] has had as much or more effect on me than any, and perhaps than all of them together."
Criticisms of environmentalism and DDT restrictions
Carson and the environmental movement were—and continue to be—criticized by some conservatives and libertarians, and chemical-industry trade groups, who argue that restrictions on the use of pesticides—specifically DDT—have caused tens of millions of needless deaths and hampered agriculture, and implicitly that Carson was responsible for inciting such restrictions. Carson's concerns about the effects on human health and the environmental impact of DDT have been intensely scrutinized. Political scientist Charles Rubin was one of the most vociferous critics in the 1980s and 1990s, though he accused her of selective use of source and fanaticism rather than the more severe criticism Carson received upon Silent Spring's release.
In the 2000s, criticism of the bans of DDT her work prompted intensified. In 2009, the libertarian think tank Competitive Enterprise Institute set up a website saying, "Millions of people around the world suffer the painful and often deadly effects of malaria because one person sounded a false alarm. That person is Rachel Carson." A 2012 review article in Nature by Rob Dunn commemorating the 50th anniversary of Silent Spring prompted a response in a letter written by Anthony Trewavas and co-signed by 10 others, including Christopher Leaver, Bruce Ames, Richard Tren and Peter Lachmann, who quote estimates of 60 to 80 million deaths "as a result of misguided fears based on poorly understood evidence".
Biographer Hamilton Lytle believes these estimates are unrealistic, even if Carson can be "blamed" for worldwide DDT policies. John Quiggin and Tim Lambert wrote, "the most striking feature of the claim against Carson is the ease with which it can be refuted". DDT was never banned for anti-malarial use, its ban for agricultural use in the United States in 1972 did not apply outside the U.S. nor to anti-malaria spraying. The international treaty that banned most uses of DDT and other organochlorine pesticides—the 2001 Stockholm Convention on Persistent Organic Pollutants—included an exemption for the use of DDT for malaria control until affordable substitutes could be found.) Mass outdoor spraying of DDT was abandoned in poor countries subject to malaria, such as Sri Lanka, in the 1970s and 1980s; this was not because of government prohibitions but because the DDT had lost its ability to kill the mosquitoes. Because of insects' very short breeding cycle and large number of offspring, the most resistant insects survive and pass on their genetic traits to their offspring, which replace the pesticide-slain insects relatively rapidly. Agricultural spraying of pesticides produces pesticide resistance in seven to ten years.)
Some experts have said that restrictions placed on the agricultural use of DDT have increased its effectiveness for malaria control. According to pro-DDT advocate Amir Attaran, the result of the 2004 Stockholm Convention banning DDT's use in agriculture "is arguably better than the status quo ... For the first time, there is now an insecticide which is restricted to vector control only, meaning that the selection of resistant mosquitoes will be slower than before." But though Carson's legacy has been closely tied to DDT, Roger Bate of the DDT advocacy organization Africa Fighting Malaria said, "A lot of people have used Carson to push their own agendas. We just have to be a little careful when you're talking about someone who died in 1964."
Silent Spring has been featured in many lists of the best nonfiction books of the twentieth century. It was fifth in the Modern Library List of Best 20th-Century Nonfiction and number 78 in the National Review's 100 best non-fiction books of the 20th century. In 2006, Silent Spring was named one of the 25 greatest science books of all time by the editors of Discover Magazine. A follow-up book, Beyond Silent Spring, co-written by H.F. van Emden and David Peakall, was published in 1996.
