Introduction to 25th anniversary edition of Silent Spring by Rachel Carson
by former Vice President Al Gore
Writing about Silent Spring is a humbling experience for an elected official, because Rachel Carson's landmark book offers undeniable proof that the power of an idea can be far greater than the power of politicians. In 1962, when Silent Spring was first published, "environment" was not even an entry in the vocabulary of public policy. In a few cities, especially Los Angeles, smog had become a cause of concern, albeit more because of its appearance than because of its threat to public health. Conservation -- the precursor of environmentalism -- had been mentioned during the 1960 Democratic and Republican conventions, but only in passing and almost entirely in the context of national parks and natural resources. And except for a few scattered entries in largely inaccessible scientific journals, there was virtually no public dialogue about the growing, invisible dangers of DDT and other pesticides and chemicals. Silent Spring came as a cry in the wilderness, a deeply felt, thoroughly researched, and brilliantly written argument that changed the course of history. Without this book, the environmental movement might have been long delayed or never have developed at all.
Not surprisingly, both the book and its author, who had once worked as a marine biologist for the Fish and Wildlife Service, met with considerable resistance from those who were profiting from pollution. Major chemical companies tried to suppress Silent Spring, and when excerpts appeared in The New Yorker, a chorus of voices immediately accused Carson of being hysterical and extremist -- charges still heard today whenever anyone questions those whose financial well-being depends on maintaining the environmental status quo. (Having been labeled "Ozone Man" during the 1992 campaign, a name that was probably not intended as a compliment but that I wore as a badge of honor, I am aware that raising these issues invariably inspires a fierce -- and sometimes foolish -- reaction.) By the time the book became widely available, the forces arrayed against its author were formidable.
The attack on Rachel Carson has been compared to the bitter assault on Charles Darwin when he published The Origin of Species. Moreover, because Carson was a woman, much of the criticism directed at her played on stereotypes of her sex. Calling her "hysterical" fit the bill exactly. Time magazine added the charge that she had used "emotion-fanning words." Her credibility as a scientist was attacked as well: opponents financed the production of propaganda that supposedly refuted her work. It was all part of an intense, well-financed negative campaign, not against a political candidate but against a book and its author.
Carson brought two decisive strengths to this battle: a scrupulous respect for the truth and a remarkable degree of personal course. She had checked and rechecked every paragraph in Silent Spring, and the passing years have revealed that her warnings were, if anything, understated. And her courage, which matched her vision, went far beyond her willingness to disturb an entrenched and profitable industry. While writing Silent Spring, she endured a radical mastectomy and then radiation treatment. Two years after the book's publication, she died, of breast cancer. Ironically, new research points strongly to a link between this disease and exposure to toxic chemicals. So in a sense, Carson was literally writing for her life.
She was also writing against the grain of an orthodoxy rooted in the earliest days of the scientific revolution: that man (and of course this meant the male of our species) was properly the center and the master of all things, and that scientific history was primarily the story of his domination -- ultimately, it was hoped, to a nearly absolute state. When a woman dared to challenge this orthodoxy, one of its prominent defenders, Robert White Stevens, replied in terms that now sound not only arrogant but as quaint as the flat-earth theory: "The crux, the fulcrum over which the argument chiefly rests, is that Miss Carson maintains that the balance of nature is a major force in the survival of man, whereas the modern chemist, the modern biologist and scientist, believes that man is steadily controlling nature."
The very absurdity of that world view from today's perspective indicates how revolutionary Rachel Carson was. Assaults from corporate interests were to be expected, but even the American Medical Association weighed in on the chemical companies' side. The man who discovered the insecticidal properties of DDT had, after all, been awarded the Nobel Prize.
But Silent Spring could not be stifled. Solutions to the problems it raised weren't immediate, but the book itself achieved enormous popularity and broad public support. In addition to presenting a convincing case, Carson had won both financial independence and public credibility with two previous bestsellers, The Sea Around Us and The Edge of the Sea. Also, Silent Spring was published in the early years of a decade that was anything but silent, a decade when Americans were perhaps far readier than they had been to hear and heed the book's message. In a sense, the woman the moment came together.
Eventually, both the government and the public became involved -- not just those who read the book, but those who read the news or watched television. As sales of Silent Spring passed the half-million mark, CBS Reports scheduled an hour-long program about it, and the network went ahead with the broadcast even when two major corporate sponsors withdrew their support. President Kennedy discussed the book at a press conference and appointed a special panel to examine its conclusions. When the panel reported its findings, its paper was an indictment of corporate and bureaucratic indifference and a validation of Carson's warnings about the potential hazards of pesticides. Soon thereafter, Congress began holding hearings and the first grassroots environmental organizations were formed.
Silent Spring planted the seeds of a new activism that has grown into one of the great popular forces of all time. When Rachel Carson died, in the spring of 1964, it was becoming clear that her voice would never be silenced. She had awakened not only our nation but the world. The publication of Silent Spring can properly be seen as the beginning of the modern environmental movement.
For me personally, Silent Spring had a profound impact. It was one of the books we read at home at my mother's insistence and then discussed around the dinner table. My sister and I didn't like every book that made it to that table, but our conversations about Silent Spring are a happy and vivid memory. Indeed, Rachel Carson was one of the reasons I became so conscious of the environment and so involved with environmental issues. Her example inspired me to write Earth in the Balance, which, not coincidentally, was published by Houghton Mifflin, the company that stood by Carson through all the controversy and that has since earned a reputation for publishing many fine books about the environmental dangers facing our world. Her picture hangs on my office wall among those of the political leaders, the presidents and the prime ministers. It has been there for years- and it belongs there. Carson has had as much or more effect on me than any of them, and perhaps than all of them together.
Both a scientist and an idealist, Carson was also a loner who listened, something that those in places of power so often fail to do. Silent Spring was conceived when she received a letter from a woman named Olga Owens Huckins in Duxbury, Massachusetts, telling her that DDT was killing birds. Today, because Carson's work led to the ban on DDT, some of the species that were her special concern- eagles and peregrine falcons, for example- are no longer at the edge of extinction. It may be that the human species, too, or at least countless human lives, will be saved because of the words she wrote.
No wonder the impact of Silent Spring has been compared to that of Uncle Tom's Cabin. Both rank among the rare books that have transformed our society. Yet there are important differences. Harriet Beecher Stowe dramatized an issue that was already on everyone's mind and at the center of a great public debate; she gave a human face to an already dominant national concern. The picture of slavery she drew moved the national conscience. As Abraham Lincoln said when he met her, at the height of the Civil War, "So you're the little lady who started this whole thing." In contrast, Rachel Carson warned of a danger that hardly anyone saw; she was trying to put an issue on the national agenda, not bear witness to one that was already there. In that sense, her achievement was harder won. Ironically, when she testified before congress in 1963, Senator Abraham Ribicoff's welcome eerily echoed Lincoln's words of exactly a century before: "Miss Carson," he said, "you are the lady who started all this."
Another difference between the books goes to the heart of Silent Spring 's continuing relevance. Slavery could be, and was, ended in a few years, although it has taken another century and more to even begin to deal with its aftermath. But if slavery could be abolished with the stroke of a pen, chemical pollution could not. Despite the power of Carson's argument, despite actions like the banning of DDT in the United States, the environmental crisis has grown worse, not better. Perhaps the rate at which the disaster is increasing has been slowed, but that itself is a disturbing thought. Since the publication of Silent Spring, pesticide use on farms alone has doubled to 1.1 billion tons a year, and production of these dangerous chemicals has increased by 400 percent. We have banned certain pesticides at home, but we still produce them and export them to other countries. This not only involves a readiness to profit by selling others a hazard we will not accept for ourselves; it also reflects an elemental failure to comprehend that the laws of science do not observe the boundaries of politics. Poisoning the food chain anywhere ultimately poisons the food chain everywhere.
In one of Carson's few speeches, and one of her last, tot he Garden Club of America, she acknowledged that things could get worse before they got better: "These are large problems, and there is no easy solution." Yet she also warned that the longer we waited, the more risks we ran: "We are subjecting whole populations to exposure to chemicals which animal experiments have proved to be extremely poisonous and in many cases cumulative in their effect. These exposures now begin at or before birth and - unless we change our methods - will continue through the lifetime of those now living. No one knows what the results will be, because we have no previous experience to guide us." Since she made these remarks, we have unfortunately gained an abundance of experience, as rates of cancer and other diseases that may be related to pesticide use have soared. The difficulty is not that we have done nothing. We have done some important things, but we have not done nearly enough.
The Environmental Protection Agency was established in 1970, in large part because of the concerns and the consciousness that Rachel Carson had raised. Pesticide regulation and the Food Safety Inspection Service were moved to the new agency from the Agriculture Department, which naturally tended to see the advantages and not the dangers of using chemicals on crops. Since 1962, Congress has called for the establishment of review, registration, and information standards for pesticides - not once, but several times. But many of these standards have been ignored, postponed, and eroded. For example, when the Clinton-Gore administration took office, standards for protecting farm workers from pesticides were still not in place, even though the EPA had been "working on them" since the early 1970s. Broad-spectrum pesticides such as DDT have been replaced by narrow-spectrum pesticides of even higher toxicity, which have not been adequately tested and present equal or even greater risks.
For the most part, hardliners within the pesticide industry have succeeded in delaying the implementation of protective measures called for in Silent Spring. It is astonishing to see the cosseting this industry has been accorded in Congress over the years. The statute that regulates pesticides, fungicides, and rodenticides sets far looser standards than those that regulate food and drugs, and Congress intentionally made them more difficult to enforce. In setting safe levels of a pesticide, the government takes into account not only its toxicity but also the economic benefit it provides. This dubious process pits increased agricultural production (which might be obtained otherwise) against potential increases in cancer and neurological disease. Moreover, the process for removing a hazardous pesticide from the market generally takes five to ten years. New pesticides, even if they are very toxic, can win approval if they work just marginally better than existing ones.
In my view, this is nothing more than the regulatory equivalent of "Been down so long it looks like up to me." The present system is a Faustian bargain - we get short-term gain at the expense of long-term tragedy. And there is reason to believe that the short term can be very short indeed. Many pesticides do not cause the total number of pests to decline; they may do so at first, but the pests eventually adapt by mutation and the chemicals become useless. Furthermore, we have focused research on pesticide effects on adults and not on children, who are especially vulnerable to these chemicals. We have examined each pesticide in isolation, but scientists generally have not yet researched combinations, which are the potentially far more perilous reality encountered in our fields and pastures and streams. Essentially, what we have inherited is a system of laws and loopholes, deadlines and delays, facades that barely disguise a wholesale failure of policy.
Rachel carson showed that the excessive use of pesticides was inconsistent with basic values; that at their worst, they create what she called "rivers of death," and at their best, they cause mild harm for relatively little long-term gain. Yet the honest conclusion is that in the twenty-two years since the publication of Silent Spring, the legal, regulatory,a nd political system has failed to respond adequately. Because Carson understood not only the environment but the very different world of politics, she anticipated one of the reasons for this failure. At a time when almost no one discussed the twin contaminations of special-interest money and influence, she referred in her Garden Club speech to the "advantage...given to those who seek to block remedial legislation." Foreshadowing the present debate about political reform, she even condemned the tax deduction for lobbying expenses that this administration has sought to repeal, pointing out that the deduction "means, to cite a specific example, that the chemical industry may now work at bargain rates to thwart future attempts at regulation... The industry wishing to pursue its course without legal restraint is now actually subsidized in its efforts." In short, the problem of politics, which she uncannilu predicted. Cleaning up politics is essential to cleaning up pollution.
The years-long failure of one endeavor helps to explain the years-long failure of the other. The results are as undeniable as they are unacceptable. In 1992, 2.2 billion pounds of pesticides were used in this country - eight pounds for every man, woman, and child. Many of the pesticides in use are known to be quite carcinogenic; others work by poisoning the nervous and immune systems of insects, and perhaps of humans. Although we no longer have the doubtful benefits of one household product that Carson described - "We can polish our floors with a wax guaranteed to dill any insect that walks over it" - today pesticides are being used on more than 900,000 farms and in 69 million homes.
In 1988, the EPA reported that the ground water in thirty-two states was contaminated with seventy-four different agricultural chemicals, including one, the herbicide atrazine, that is classified as a potential human carcinogen. Seventy million tons a year are used on cornfields in the Mississippi basin, and 1.5 million pounds of runoffs now flow into the drinking water of 20 million people. Atrazine is not removed by municipal water treatment; in springtime, the amount of atrazine in the water often exceeds the standards set by the Safe Drinking Water Act. In 1993, that was true for 25 percent of all the surface water in the entire Mississippi basin.
DDT and PCBs are virtually banned in the United States for other reasons, but pesticides that mimic the female hormone estrogen, which are close chemical cousins, are plentiful and are raising intense new concerns. Research from Scotland, Michigan, Germany, and elsewhere indicates that they lead to reduced fertility, testicular and breast cancer, and malinformation of the genital organs. In the United States alone, as the tide of estrogen pesticides has crested in the past twenty years, the incidence of testicular cancer has risen by approximately 50 percent. The evidence also suggests that, for reasons not yet understood, there has recently been a worldwide drop in sperm counts of 50 percent. There is documented, irrefutable proof that these chemicals disrupt the reproductive capacity of wildlife. As three researchers concluded after reviewing the data for the Journal of the Institute of Environmental Health Services, "Today many wildlife populations are at risk." Many of these problems may be harbingers of vast and unpredictable changes in animal and human reproductive systems, but the pesticides' potentially harmful effects are not currently considered in regulatory risk assessment. A new administration proposal calls for this kind of review.
Defenders of these chemicals will no doubt provide the traditional responses: that studies using human subjects don't demonstrate a direct link between the chemicals and disease; that coincidence doesn't equal casuality (although some coincidences strongly point to making a prudent instead of a reckless decision); and, the old standby, that tests animals don't always, absolutely, inescapably translate to the same results in the human species. Each of these answers recalls the kind of reflexive response that Rachel Carson's work elicited from the chemical industry and the university scientists it subsidized. She anticipated the response, and wrote in Silent Spring of a public "fed little tranquilizing pills of half-truths. We urgently need an end to these false assurances, to the sugarcoating of unpalatable facts."
In the 1980s, especially when James Watt was at the Interior Department and Ann Gorsuch was at the EPA, the environmental know-nothings reached the peak of their influence. Poisoning the environment was almost regarded as a sign of hard-nosed economic pragmatism. In the Gorsuch EPA, for example, integrated pest management (IPM), the alternative to chemical pesticides, was literally declared anathema. The EPA banned publications about it, and certification of IPM methods was outlawed.
The Clinton-Gore administration began with a different view, and with a firm determination to turn the tide of pesticide pollution. Our policy pursues three imperatives: tougher standards, reduced use, and broader use of alternative biological agents.
Obviously, a sensible approach to pesticide use has to balance dangers and benefits and take economic factors into account. But we also have to take the heavy weight of special interests off the scale and out of the equation. The standards have to be clear and demanding, and the testing has to be thorough and honest. For too long we have set tolerance levels for pesticide residues in children hundreds of times higher than they should be. What calculus of economic benefits can justify this? We have to test the effects of these chemicals on children, not just adults, and we have to test a range of varying combinations. We must test not just to limit fear, but to limit what we have to fear.
If a pesticide isn't needed or doesn't work in a given situation, then the presumption should be against use, not for it. The benefit should be real, not possible, transitory, or speculative.
Above all, we have to focus on the biological agents for which the industry and its political apologists have such intense hostility. In Silent Spring , Carson wrote of the "truly extraordinary array of alternatives to the chemical control of insects/" The array is wider today, despite the indifference of too many public officials and the resistance of manufacturers. Why don't we push hard for the use of nontoxic substances?
Finally, we must begin to bridge the cultural divide between the pesticide-production and agricultural community on the one side and the public health community on the other. People in the two communities come from different backgrounds, go to different colleges, and have very different viewpoints. As long as they face each other across a gulf of suspicion and enmity, we will find it hard to change a system in which production and profit are tied to pollution. One way in which we can signal the end of that system - and begin to narrow the cultural divide - is by having the Agricultural Extension Service promote alternatives to chemical solutions. Another is by instituting formal, ongoing dialogue between those who produce our food and those who protect our health.
The Clinton-Gore administration's new policy regarding pesticides has many architects. Maybe the most important is a woman whose last official government service came in 1952, when she resigned from her mid-level civil service position so she could write full-time, not just on weekends and at night. In spirit, Rachel Carson sits in on all the important environmental meetings of this administration. We may not do everything she would want, all at once, but we are moving in the direction she indicated.
In 1992, a panel of distinguished Americans selected Silent Spring as the most influential book of the last fifty years. Across those years and through all the policy debates, this book continues to be the voice of reason breaking in on complacency. It brought environmental issues to the attention not just of industry and government; it brought them to the public, and put our democracy itself on the side of saving the Earth. More and more, consumer power will work against pesticide pollution, eve when government does not. Reducing pesticides in food is now becoming a marketing tool as well as a moral imperative. The government must act, but the people can also decide - and I am convinced that the people will no longer let the government do nothing, or do the wrong thing.
Rachel Carson's influence reaches beyond the boundaries of her specific concerns in Silent Spring. She brought us back to a fundamental idea lost to an amazing degree in modern civilization: the interconnection of human beings and the natural environment. This book was a shaft of light that for the first time illuminated what is arguably the most important issue of our era. In Silent Spring's final pages, Carson described the choice before us in terms of Robert Frost's famous poem about the road "less traveled." Others have taken that road; few have taken the world along with them, as Carson did. Her work, the truth she brought to light, the science and research she inspired, stand not only as powerful arguments for limiting the use of pesticides but as powerful proof of the difference that one individual can make.
Earlier Class Paper on the Impact of Rachel Carson
Rachel Carson’s Silent Spring and the Beginning of the Environmental Movement in the United States
When Rachel Carson's Silent Spring was published in 1962, it generated a storm of controversy over the use of chemical pesticides. Miss Carson's intent in writing Silent Spring was to warn the public of the dangers associated with pesticide use. Throughout her book are numerous case studies documenting the harmful effects that chemical pesticides have had on the environment. Along with these facts, she explains how in many instances the pesticides have done more harm than good in eradicating the pests they were designed to destroy. In addition to her reports on pesticide use, Miss Carson points out that many of the long-term effects that these chemicals may have on the environment, as well as on humans, are still unknown. Her book as one critic wrote, “dealt pesticides a sharp blow” (Senior Scholastic 1962). The controversy sparked by Silent Spring led to the enactment of environmental legislation and the establishment of government agencies to better regulate the use of these chemicals.
Miss Carson first became aware of the effects of chemical pesticides on the natural environment while working for the U.S. Bureau of Fisheries. Of particular concern to her was the government’s use of chemical pesticides such as DDT. She was familiar with early studies of DDT and knew of its dangers and lasting effects on the environment. According to Miss Carson, “the more I learned about the use of pesticides, the more appalled I became. I realized that here was the material for a book. What I discovered was that everything which meant most to me as a naturalist was being threatened, and that nothing I could do would be more important.” Thus,Silent Spring was written to alert the public and stir people to action against the abuse of chemical pesticides (Time 2000).
Impact of Silent Spring
When excerpts of Silent Spring first began appearing in The New Yorker magazine in June 1962, theycaused an uproar and brought a “howl of indignation” from the chemical industry. Supporters of the pesticide industry argued that her book gave an incomplete picture because it did not say anything about the benefits of using pesticides. An executive of the American Cyanamid Company complained, “if man were to faithfully 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.” Chemical manufacturers began undertaking a more aggressive public relations campaign to educate the public on the benefits of pesticide use. Monsanto, for example, published and distributed 5,000 copies of a brochure “parodying” Silent Spring entitled “The Desolate Year,” which explained how chemical pesticides were largely responsible for the virtual eradication of diseases such as malaria, yellow fever, sleeping sickness, and typhus in the United States and throughout the world, and that without the assistance of pesticides in agricultural production millions around the world would suffer from malnutrition or starve to death (NRDC 1997).
One of the main counterarguments to Miss Carson's book expressed by the farmers, scientists, and other supporters of the pesticide industry was that farm yields would be drastically reduced without the assistance of chemical pesticides. Scientists from the Department of Agriculture argued, that the world would not be able to feed itself without pesticides (Darby 1962). George C. Decker, an entomologist at the Illinois Agricultural Experiment Station, explainedthat:
if we in North America were to adopt a policy of let nature take its course, as some individuals thoughtlessly advocate, it is possible that these would‑be experts would find the disposing of the 200 million surplus human beings even more perplexing that the disposition of American's current corn, cotton and wheat surpluses." (Time 1962).
Ironically, the attempts of the chemical industry to discredit Miss Carson gave her book even more publicity. In fact, public support in favor of Miss Carson's position was enormous. Justice William O. Douglas called the book “the most important chronicle of this century for the human race” (Business Week 1962). An article published in Business Week noted that ever since excerpts of her book began appearing in The New Yorker, “Miss Carson has had a heavy mail reaction, almost all endorsing her theme.” An editor from The New Yorker said that Miss Carson's mail response was probably the largest since John Hersey's Hiroshima. All of the fanfare spawned by Silent Spring compelled the Book‑of-the-Month Club to run 150,000 copies of the book just for the club's first distribution (Saturday Review 1962).
It was not too long after Silent Spring was in print that the public's awareness of the dangers associated with pesticide use impelled them to began taking steps to limit the use of these chemicals in their communities. In Squirrel Island Maine, for example, residents voted to cancel a planned aerial spraying of the island. Also, in Texas, twice as many members as usual attended the yearly National Audubon Society convention where one of the topics up for debate was discussing the effects that DDT has on wildlife (Senior Scholastic 1962). Many of these concerned citizens felt that we should discontinue using these chemicals and let the age‑old balance of nature take care of obnoxious insects (Time 1962).
Around the same time that Miss Carson began receiving her fan mail, letters expressing "horror and amazement" at the chemical pesticide practices discussed in Silent Spring began piling up at the offices of the Department of Agriculture (Saturday Review 1962). The growing concerns over pesticide use prompted President Kennedy to order the President’s Science Advisory Committee to conduct an investigation to determine the dangers that these chemicals represent to humans and the environment as well as to consider if it was necessary to enact new legislation regulating the use of chemical pesticides. When the Committee's study was completed in May 1963, it vindicated Miss Carson. According to Bruce Frisch of Science Digest, the Committee found that there were immediate and long‑range hazards to man and other animals and that the government had not been protecting against them or learning exactly what they were (Science Digest 1964). Eventually, after the Committee's report was issued, several pieces of federal environmental legislation were passed into law by Congress, including the ban on DDT use in the United States, which was due in large part to the issues Miss Carson raised in Silent Spring (Field 1997).
Why Silent Spring was so Effective in Arousing Public Concern
Even though she was labeled as hysterical and extremist by the chemical industry and certain members of the media, their attempts to discredit Miss Carson by challenging her credibility as a scientist backfired. The onslaught of attacks on Miss Carson by the chemical industry were viewed negatively by the public, because the industry was seen as attacking a sincere woman who was already regarded as an accomplished writer and scientist from the fame and recognition she received for her 1951 book, The Sea Around Us. Furthermore, Silent Spring was well documented with 55 pages of references and included a list of scientific experts that had reviewed her book (Lear 1997).
Another reason that Miss Carson was so effective in generating pubic opposition to pesticide use was her ability to incorporate into her book real-world examples of how pesticides were negatively impacting the environment. For instance, in explaining how pesticides sometimes kill many other forms of life which are not targeted, she cites as an example the significant decline in young salmon populations that occurred in Northwest Miramichi after DDT spraying was performed in the area to protect the balsam forests from the spruce budworm. In addition to killing the spruce budworm, Miss Carson explains, that DDT also killed the aquatic insects which the young salmon depend on for food and therefore left nothing for the young salmon to eat.
In another example, she explains how DDT spraying was initiated during the mid 1950s to fight the spread of Dutch Elm disease that was destroying the elm trees on the campus of Michigan State University and indirectly killed a large number of robins that fed in the area. Although the spraying was aimed at eradicating the bark beetle which was spreading the disease, all parts of the trees were sprayed with the poison. Therefore, because the leaves of the trees were also coated with the insecticide, earthworms feeding on the leaves absorbed the poison and robins which later ate the contaminated worms died of DDT poisoning.
The examples that Miss Carson wrote about in Silent Spring helped to illustrate the interrelationship of living organisms. Her writings helped Americans to understand that humans were not separate from nature, but connected to the earth as part of an interconnected web of life (Brooks 1972). In writing about the above events, Miss Carson concludes:
For each of us, as for the robin in Michigan, or the salmon in the Miramichi, this is a problem of ecology, of interrelationships, of interdependence. We poison the caddis flies in the stream and the salmon runs dwindle and die. . . . We spray our elms and following springs are silent of robin song, not because we sprayed the robins directly but because the poison traveled, step by step, through the now familiar elmleaf ‑earthworm‑robin cycle. These are matters of record, observable, part of the visible world around us. They reflect the web of life‑or death‑that scientists know as ecology.
Another way that Silent Spring helped to engender support against pesticides is its discussion regarding the potential impacts of these chemicals on human health. In her book, Miss Carson points out that because very little medical research has been conducted to determine what effects these chemicals may have on humans, individuals should be cautious in how they are used in the environment. Furthermore, she warns that since many of these chemicals accumulate in the tissues of living organisms, they pose potential long‑term genetic and carcinogenic dangers to humans and other creatures. To bolster her argument, Miss Carson cites the opinions of several doctors and medical researchers, who believe that there is a strong link between certain types of malignant diseases and exposure to chemical pesticides.
Miss Carson was not arguing that we should ban chemical pesticides all together, but that we should be more careful in our application of these chemicals, since all species including humans are interconnected with one another and killing one species may endanger others. Says Miss Carson: “it is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm.” She explains that by trying to control these pests with chemical pesticides, we are upsetting the balance of nature. It is a battle we cannot win she says, because “as crude a weapon as the cave man's club, the chemical barrage has been hurled against the fabric of life—a fabric on one hand delicate and destructible, on the other miraculously tough and resilient, and capable of striking back in unexpected ways.”
Miss Carson also lets her readers know that there are viable alternatives to controlling insects and other pests without the use of chemical pesticides. Miss Carson makes the argument that in many instances natural or ecological methods offer a better alternative to combating pests. She provides several examples throughout her book of cases where biological methods “have achieved brilliant success” in controlling insects and other pests. In one case, she reports how two species of beetles from southern France were shipped to the United States to control the outgrowth of the Klamath weed which had evolved into an epidemic in California. Miss Carson explains that these beetles are natural predators of the Klamath weed and in Europe they feed on it so extensively that its abundance is severely limited. Consequently, their introduction in North America has had similar results in reducing Klamath weed populations and allowing native plant species to return. Moreover, Miss Carson says that because many insects become immune to the chemicals that are used against them, scientists are forced to develop even more toxic insecticides in order to decimate these resistant pests.
According to Miss Carson, using biological solutions to control undesirable pests is a much better alternative than conventional chemical pesticides, because these non‑chemical methods do not leave any poisonous residues that can contaminate and harm the environment. Accordingly, she strongly urged that more research be conducted in the area of biological control and that these alternative approaches be considered first before more toxic methods are employed.
Silent Spring not only attacked the integrity of the chemical industry, but also challenged the credibility of the government. The general public knew only of the benefits of using chemical pesticides and trusted the government that these chemicals were safe to use. However, the issues that Miss Carson raised made people more aware of the pesticide spraying that was going on in their neigborhoods. As Dr. W.C. Hueper, of the National Cancer Institute said, "anyone who has watched the dusters and sprayers of arsenical insecticides at work must have been impressed by the almost supreme carelessness with which the poisonous substances are dispensed” (Naum 1999).
The eloquent writing and imagery in Silent Spring painted a picture about what might happen to our world if we continued indiscriminately bombarding the environment with chemical pesticides:
There was once a town in the heart of America where all life seemed to live in harmony with its surroundings...Then a strange blight crept over the area and everything began to change...There was a strange stillness...The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of scores of bird voices there was now no sound; only silence lay over the fields and woods and marsh.
After the publication of Silent Spring, communities began to organize into groups to voice their concern to the government about pesticide spraying. In fact,many argue that Silent Spring was instrumental in launching the American and global environmental movements as well as the notion that we possess a fundamental right to a clean environment. Several environmental interest groups including the Natural Resources Defense Council, the Wilderness Society, and the Environmental Defense Fund were formed after the publication of Silent Spring. Environmental interest groups are able to influence the policy process by manipulating public opinion and persuading legislators and committees to support their issues. Legislators want to support issues their constituents support because it is their representative responsibility and because they want to be re-elected (Vig and Kraft 1997).
Additionally, many believe that the establishment of the Environmental Protection Agency in 1970, can largely be attributed to the “concerns and the consciousness” that Rachel Carson raised in her book. Pesticide regulation, once the responsibility of Agriculture Department, which not surprisingly tended to only see the benefits and not the dangers of using chemical pesticides, was moved under the authority of the EPA (Benjamin 1996). With the creation of the EPA came the passage of several pieces of environmental legislation including the Clean Air Act, the Federal Environmental Pesticide Control Act, and the Safe Drinking Water Act.
Silent Spring helped to expose the hazards of chemical pesticide use and draw public attention to environmental issues that had never really been addressed before. In fact, as University of Colorado School of Law Professor David Getches points out, Miss Carson's book recently was named the most influential book of our time by a panel of leading Americans (MacDonnell 1993). One critic at the time of the book's publication correctly predicted that Silent Spring could do for the control of chemical pollution of our environment what Upton Sinclair's The Jungle did for the Pure Food and Drug Act in 1906 (Vogt 1962). As Al Gore explains, Silent Spring “brought environmental issues to the attention not just of industry and government; it brought them to the public, and put our democracy itself on the side of saving the Earth” (Gore 1994). The onslaught of environmental legislation that occurred after the publication of Silent Spring allowed environmentalism to find credibility in our society, and its practice to become a permanent force in public policy.
