《寂静的春天》(Silent Spring)

《寂静的春天》（Silent Spring）《寂静的春天》（SilentSpring）于1972～1977年间陆续译为中文，开首的几章曾在中国科学院地球化学研究所编辑出版的学术刊物“环境地质与健康”上登载过，全书于1979年由科学出版社正式出版。

20年后的今天，我们高兴地看到，在中国社会科学院哲学研究所吴国盛先生及吉林人民出版社的协同努力下，这本书得以纳入《绿色经典文库》再版。

我们衷心希望，这本彪炳史册的著作为中国环境保护事业带来的启迪和推动，能够继续下去。

《寂静的春天》1962年在美国问世时，是一本很有争议的书。

它那惊世骇俗的关于农药危害人类环境的预言，不仅受到与之利害悠关的生产与经济部门的猛烈抨击，而且也强烈震撼了社会广大民众。

你若有心去翻阅本世纪60年代以前的报纸或书刊，你将会发现几乎找不到“环境保护”这个词。

这就是说，环境保护在那时并不是一个存在于社会意识和科学讨论中的概念。

确实，回想一下长期流行于全世界的口号——“向大自然宣战”、“征服大自然”，在这儿，大自然仅仅是人们征服与控制的对象，而非保护并与之和谐相处的对象。

人类的这种意识大概起源于洪荒的原始年月，一直持续到20世纪。

没有人怀疑它的正确性，因为人类文明的许多进展是基于此意识而获得的，人类当前的许多经济与社会发展计划也是基于此意识而制定的。

蕾切尔．卡逊(Rachel Carson)第一次对这一人类意识的绝对正确性提出了质疑。

这位瘦弱、身患癌症的女学者，她是否知道她是在向人类的基本意识和几千年的社会传统挑战?《寂静的春天》出版两年之后，她心力交瘁，与世长辞。

作为一个学者与作家，卡逊所遭受的诋毁和攻击是空前的，但她所坚持的思想终于为人类环境意识的启蒙点燃了一盏明亮的灯。

蕾切尔．卡逊1907年5月27日生于宾夕法尼亚州泉溪镇，并在那儿度过童年。

她1935年至1952年间供职于美国联邦政府所属的鱼类及野生生物调查所，这使她有机会接触到许多环境问题。

[VIP专享]精读 silent spring 原文寂静的春天(同飞君)

There was once a town in the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of colour that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the autumn mornings.Along the roads, laurel, viburnum and alder, great ferns and wild flowers, delighted the traveller's eye through much of the year. Even in winter the roadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and autumn people travelled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their houses, sank their wells and built their barns.Then a strange blight crept over the area and everything began to change. Some evil spell had settled on the community: mysterious maladies swept the flocks of chickens; the cattle and sheep sickened and died. Everywhere was a shadow of death. The farmers spoke of much illness among their families. In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients. There had been several sudden and unexplained deaths not only among adults but even among children, who would be stricken suddenly while at play and die within a few hours.There was a strange stillness. The birds, for example — where had they gone Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. 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 robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.On the farms the hens brooded, but no chicks were hatched. The farmers complained that they were unable to raise any pigs — the litters were small and the young survived only a few days. The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.The roadsides, once so attractive, were now lined with browned and withered vegetation as though swept by fire. These too, were silent, deserted by all living things. Even the streams were now lifeless. Anglers no longer visited them, for all the fish had died.In the gutters under the eaves and between the shingles of the roofs, white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams.No witchcraft, no enemy action had silenced the rebirth of new life in this stricken world.

A Gordo Sunday cartoon marking the passing of Rachel Carson in 1964
The Rachel Carson Bridge in Pittsburgh
Background By tradition and by Carson's own public assertions, the impetus for Silent Spring was ostensibly a letter written in January 1958 by Carson's friend, Olga Owens Huckins, to The Boston Herald, describing the death of numerous birds around her property resulting from the aerial spraying of DDT to kill mosquitoes, a copy of which Huckins sent to Carson. Carson has stated that the letter prompted her to turn her attention to environmental problems caused by chemical pesticides.
Criticism It was the opinion of celebrated writer, naturalist, and environmental activist Peter Matthiessen writing in Time Magazine in 1999 that even before Silent Spring was published by Houghton Mifflin in 1962 that there was strong opposition to it: Carson was violently assailed by threats of lawsuits and derision, including suggestions that this meticulous scientist was a "hysterical woman" unqualified to write such a book. A huge counterattack was organized and led by Monsanto Company, Velsicol, American Cyanamid – indeed, the whole chemical industry – duly supported by the Agriculture Department as well as the more cautious in the media.

I then realized I must write this book.During the years since then I have received help and encouragement from so many people that it is not possible to name them all here. Those who have freely shared with me the fruits of many ye ars’ experience and study represent a wide variety of government agencies in this and other countries, many universities and research institutions, and many professions. To all of them I express my deepest thanks for time andthought so generously given.In addition my special gratitude goes to those who took time to read portions of the manuscript and to offer comment and criticism based on their own expert knowledge. Although the final responsibility for the accuracy and validity of the text is mine, I could not have completed the book without the generous help of these specialists: L. G. Bartholomew, M.D., of the Mayo Clinic, John J. Biesele of the University of Texas, A. W.A. Brown of the University of Western Ontario, Morton S. Biskind, M.D., of Westport, Connecticut, C. J. Briejer of the Plant Protection Service in Holland, Clarence Cottam of the Rob and Bessie Welder Wildlife Foundation, George Crile, Jr., M.D., of the Cleveland Clinic, Frank Egler of Norfolk, Connecticut, Malcolm M. Hargraves, M.D., of the Mayo Clinic, W.C. Hueper, M.D., of the National Cancer Institute, C. J. Kerswill of the Fisheries Research Board of Canada, Olaus Murie of the Wilderness Society, A. D. Pickett of the Canada Department of Agriculture, Thomas G. Scott of the Illinois Natural History Survey, Clarence Tarzwell of the Taft Sanitary Engineering Center, and George J. Wallace of Michigan State University. Every writer of a book based on many diverse facts owes much to the skill and helpfulness of librarians. I owe such a debt to many, but especially to Ida K. Johnston of the Department of the Interior Library and to Thelma Robinson of the Library of the National Institutesof Health. As my editor, Paul Brooks has given steadfast encouragement over the years and has cheerfully accommodated his plans to postponements and delays. For this, and for his skilled editorial judgment, I am everlastingly grateful. I have had capable and devoted assistance in the enormous task of library research from Dorothy Algire, Jeanne Davis, and Bette Haney Duff. And I could not possibly have completed the task, under circumstances sometimes difficult, except for the faithful help of my housekeeper, Ida Sprow.Finally, I must acknowledge our vast indebtedness to a host of people, many of them unknown to me personally, who have nevertheless made the writing of this book seem worthwhile. These are the people who first spoke out against the reckless and irresponsible poisoning of the world that man shares with all other creatures, and who are even now fighting the thousands of small battles that in the end will bring victory for sanity and common sense in our accommodation to the world that surrounds us.ForewordIN 1958, when Rachel Carson undertook to write the book that becameSilent Spring, she was fifty years old. She had spent most of her professional life as a marine biologist and writer with the U.S. Fish and Wildlife Service. But now she was a world-famous author, thanks to the fabulous success of The Sea Around Us, published seven years before. Royalties from this book and its successor, The Edge of the Sea, had enabled her to devote full time to her own writing.To most authors this would seem like an ideal situation: an established reputation, freedom to choose one’s own subjec t, publishers more than ready to contract for anything one wrote. It might have been assumed that her next book would be in a field that offered the same opportunities, the same joy in research, as did its predecessors. Indeed she had such projects in mind. But it was not to be.While working for the government, she and her scientific colleagues had become alarmed by the widespread use of DDT and other long-lasting poisons in so-called agricultural control programs. Immediately after the war, when these dangers had already been recognized, she had tried in vain to interest some magazine in an article on the subject. A decade later, when the spraying of pesticides and herbicides (some of them many times as toxic as DDT) was causing wholesale destruction of wildlife and its habitat, and clearly endangering human life, she decidedshe had to speak out. Again she tried to interest the magazines in an article. Though by now she was a well-known writer, the magazine publishers, fearing to lose advertising, turned her down. For example, a manufacturer of canned baby food claimed that such an article would cause “unwarranted fear” to mothers who used his product. (The one exception was The New Yorker, which would later serialize parts of Silent Spring in advance of book publication.)So the only answer was to write a book—book publishers being free of advertising pressure. Miss Carson tried to find someone else to write it, but at last she decided that if it were to be done, she would have to do it herself. Many of her strongest admirers questioned whether she could write a salable book on such a dreary subject. She shared their doubts, but she went ahead because she had to. “There would be no peace for me,” she wrote to a friend, “if I kept silent.”Silent Spring was over four years in the making. It required a very different kind of research from her previous books. She could no longer recount the delight s of the laboratories at Woods Hole or of the marine rock pools at low tide. Joy in the subject itself had to be replaced by a sense of almost religious dedication. And extraordinary courage: during the final years she was plagued with what she termed “a wholecatalogue of illnesses.”Also she knew very well that she would be attacked by the chemical industry. It was not simply that she was opposing indiscriminate use of poisons but—more fundamentally—that she had made clear the basic irresponsibility of an industrialized, technological society toward the natural world. When the attack did come, it was probably as bitter and unscrupulous as anything of the sort since the publication of Charles Darwin’s Origin of Species a century before. Hundreds of thousands of dollars were spent by the chemical industry in an attempt to discredit the book and to malign the author—she was described as an ignorant and hysterical woman who wanted to turn the earth over to the insects.These attacks fortunately backfired by creating more publicity than the publisher possibly could have afforded. A major chemical company tried to stop publication on the grounds that Miss Carson had made a misstatement about one of their products. She hadn’t, and publication proceeded on schedule.She herself was singularly unmoved by all this furor狂热；激怒. Meanwhile, as a direct result of the message in Silent Spring, President Kennedy set up a special panel of his Science Advisory Committee to study theproblem of pesticides. The panel’s report, when it appeared some months later, was a complete vindication of her thesis.Rachel Carson was very modest about her accomplishment. As she wrote to a close friend when the manuscript was nearing completion: “The beauty of the living world I was trying to save has always been uppermost in my mind—that, and anger at the senseless, brutish things that were being done.... Now l can believe I have at least helped a little.” In fact, her book helped to make ecology, which was an unfamiliar word in those days, one of the great popular causes of our time. It led to environmental legislation at every level of government.Twenty-five years after its original publication, Silent Spring has more than a historical interest. Such a book bridges the gulf between what C. P. Snow called “the two cultures.” Rachel Carson was a realistic, well-trained scientist who possessed the insight and sensitivity of a poet. She had an emotional response to nature for which she did not apologize. The more she learned, the greater grew what she termed “the sense of wonder.” So she succeeded in making a book about death a celebration of life.Rereading her book today, one is aware that its implications are farbroader than the immediate crisis with which it dealt. By awaking us to a specific danger—the poisoning of the earth with chemicals—she has helped us to recognize many other ways (some little known in her time) in which mankind is degrading the quality of life on our planet. And Silent Spring will continue to remind us that in our overorganized and overmechanized age, individual initiative and courage still count: change can be brought about, not through incitement煽动，刺激to war or violent revolution, but rather by altering the direction of our thinking about the world we live in.1. A Fable for T omorrowTHERE WAS ONCE a town in the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple（枫树）and birch set up a blaze of color that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the fall mornings.Along the roads, laurel, viburnum and alder, great ferns and wildflowers delighted the traveler’s eye through much of the year. Even in winter theroadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and fall, people traveled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their houses, sank their wells, and built their barns.Then a strange blight crept over the area and everything began to change. Some evil spell had settled on the community: mysterious maladies swept the flocks of chickens; the cattle and sheep sickened and died. Everywhere was a shadow of death. The farmers spoke of much illness among their families. In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients. There had been several sudden and unexplained deaths, not only among adults but even among children, who would be stricken suddenly while at play and die within a few hours.There was a strange stillness. The birds, for example—where had they gone? Many people spoke of them, puzzled and disturbed. The feedingstations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices.

These, too, were silent, deserted by all living things. Even the streams were now lifeless. Anglers no longer visited them, for all the fish had died.In the gutters（排水沟）under the eaves（屋檐）and between the shingles of the roofs, a white granular（颗粒状的）powder still showed a few patches; Some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams. No witchcraft, no enemy actionhad silenced the rebirth of new life in this stricken world. The people had done it themselves.This town does not actually exist, but it might easily have a thousand counterparts in America or elsewhere in the world. I know of no community that has experienced all the misfortunes I describe. Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim specter has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.What has already silenced the voices of spring in countless towns in America? This book is an attempt to explain.2. The Obligation to EndureTHE HISTORY OF LIFE on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. Only within the moment of timerepresented by the present century has one species—man—acquired significant power to alter the nature of his world.During the past quarter century this power has not only increased to one of disturbing magnitude but it has changed in character. The most alarming of all man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal (d e a d l y) materials. This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible. In this now universal contamination of the environment, chemicals are the sinister and little-recognized partners of radiation in changing the very nature of the world—the very nature of its life. Strontium 90, released through nuclear explosions into the air, comes to earth in rain or drifts down as fallout(放射性尘埃), lodges in soil, enters into the grass or corn or wheat grown there, and in time takes up its abode in the bones of a human being, there to remain until his death. Similarly, chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and, through the alchemy (magic) of air and sunlight, combine into new forms that kill vegetation, sicken cattle, and work unknownharm on those who drink from once pure wells. As Albert Schweitzer has said, ‘Man can hardly even recognize the devils of his own creation.’It took hundreds of millions of years to produce the life that now inhabits the earth—eons of time in which that developing and evolving and diversifying life reached a state of adjustment and balance with its surroundings. The environment, rigorously shaping and directing the life it supported, contained elements that were hostile as well as supporting. Certain rocks gave out dangerous radiation; even within the light of the sun, from which all life draws its energy, there were short-wave radiations with power to injure. Given time—time not in years but in millennia—life adjusts, and a balance has been reached. For time is the essential ingredient; but in the modern world there is no time.The rapidity of change and the speed with which new situations are created follow the impetuous (rude, violent) and heedless pace of man rather than the deliberate pace of nature. Radiation is no longer merely the background radiation of rocks, the bombardment of cosmic rays, the ultraviolet (紫外线) of the sun that have existed before there was any life on earth; Radiation is now the unnatural creation of man’s tampering (intervene) with the atom. The chemicals to which life is asked to make its adjustment are no longer merely the calcium and silica and copperand all the rest of the minerals washed out of the rocks and carried in rivers to the sea; they are the synthetic creations of man’s inventiv e mind, brewed in his laboratories, and having no counterparts in nature.To adjust to these chemicals would require time on the scale that is nature’s; it would require not merely the years of a man’s life but the life of generations. And even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. The figure is staggering and its implications are not easily grasped—500 new chemicals to which the bodies of men and animals are required somehow to adapt each year, chemicals totally outside the limits of biologic experience.Among them are many that are used in man’s war against nature. Since the mid-1940s over 200 basic chemicals have been created for use in killing insects, weeds, rodents(n. 啮齿动物，啮齿类),and other organisms described in the modern vernacular as ‘pests’; and they are sold under several thousand different brand names.These sprays, dusts, and aerosols (气雾剂, 喷雾)are now applied almost universally to farms, gardens, forests, and homes—nonselectivechemicals that have the power to kill every insect,the ‘good’ and the ‘bad’, to still the song of birds and the leaping of fish in the streams, to coat the leaves with a deadly film, and to linger on in soil—all this though the intended target may be only a few weeds or insects. Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life? They should not be called ‘insecticides’, but ‘biocides’.The whole process of spraying seems caught up in an endless sp iral.Since DDT was released for civilian use, a process of escalatio n (n. 增加；扩大；逐步上升) has been going on in which ever more toxic materials must be found. This has happened because insects, in a triumphant vindication of Darwin’s principle of the survival of the fittest, have evolved super races immune to the particular insecti cide used, hence a deadlier one has always to be developed—and then a deadlier one than that. It has happened also because, for reasons to be described later, destructive insects often undergo a ‘flareback’, or resurgence, after spraying, in numbers greater than before. Thus the chemical war is never won, and all life is caugh t in its violent crossfire.Along with the possibility of the extinction of mankind by nuclear war,the central problem of our age has therefore become the contamination of man’s total environment with such substances of incredible potential for harm—substances that accumulate in the tissues of plants and animals and even penetrate the germ cells to shatter or alter the very material of heredity upon which the shape of the future depends. Some would-be architects of our future look toward a time when it will be possible to alter the human germ plasm by design. But we may easily be doing so now by inadvertence, for many chemicals, like radiation, bring about gene mutations. It is ironic to think that man might determine his own future by something so seemingly trivial as the choice of an insect spray.All this has been risked—for what? Future historians may well be amazed by our distorted sense of proportion. How could intelligent beings seek to control a few unwanted species by a method that contaminated the entire environment and brought the threat of disease and death even to their own kind? Yet this is precisely what we have done. We have done it, moreover, for reasons that collapse the moment we examine them. We are told that the enormous and expanding use of pesticides is necessary to maintain farm production. Yet is our real problem not one of overproduction? Our farms, despite measures to remove acreages from production, and to pay farmers notto produce, have yielded such a staggering excess of crops that the American taxpayer in 1962 is paying out more than one billion dollars a year as the total carrying cost of the surplus-food storage program. And is the situation helped when one branch of the Agriculture Department tries to reduce production while another states, as it did in 1958, ‘It is believed generally that reduction of crop acreages under provisions of the Soil Bank will stimulate interest in use of chemicals to obtain maximum pro duction on the land retained in crops.’All this is not to say there is no insect problem and no need of control. I am saying, rather, that control must be geared to realities, not to mythical situations, and that the methods employed must be such that they do not destroy us along with the insects.The problem whose attempted solution has brought such a train of disaster in its wake is an accompaniment of our modern way of life. Long before the age of man, insects inhabited the earth—a group of extraordinarily varied and adaptable beings. Over the course of time since man’s advent (n. 到来；出现；基督降临；基督降临节), a small percentage of the more than half a million species of insects have come into conflict with human welfare in two principal ways: as competitors for the food supply and as carriers of human disease.Disease-carrying insects become important where human beings are crowded together, especially under conditions where sanitation is poor, as in time of natural disaster or war or in situations of extreme poverty and deprivation. Then control of some sort becomes necessary. It is a sobering fact, however, as we shall presently see, that the method of massive chemical control has had only limited success, and also threatens to worsen the very conditions it is intended to curb (restrain).Under primitive agricultural conditions the farmer had few insect problems. These arose with the intensification of agriculture—the devotion of immense acreages to a single crop. Such a system set the stage for explosive increases in specific insect populations. Single-crop farming does not take advantage of the principles by which nature works; it is agriculture as an engineer might conceive it to be. Nature has introduced great variety into the landscape, but man has displayed a passion for simplifying it. Thus he undoes the built-in checks and balances by which nature holds the species within bounds.One important natural check is a limit on the amount of suitable habitat for each species. Obviously then, an insect that lives on wheat can build up its population to much higher levels on a farm devoted to wheat than onone in which wheat is intermingled with other crops to which the insect is not adapted.The same thing happens in other situations. A generation or more ago, the towns of large areas of the United States lined their streets with the noble elm tree (榆树). Now the beauty they hopefully created is threatened with complete destruction as disease sweeps through the elms, carried by a beetle that would have only limited chance to build up large populations and to spread from tree to tree if the elms were only occasional trees in a richly diversified planting.Another factor in the modern insect problem is one that must be viewed against a background of geologic and human history: the spreading of thousands of different kinds of organisms from thei r native homes to invade new territories. This worldwide migratio n has been studied and graphically described by the British ecolog ist Charles Elton in his recent book The Ecology of Invasions. Duri ng the Cretaceous(n. 白垩纪；白垩系adj. 白垩纪的；似白垩的)Period, some hun dred million years ago, flooding seas cut many land bridges betwe en continents and living things found themselves confined in what Elton calls ‘colossal separate nature reserves’. There, isolated from others of their kind, they developed many new species. When some of the land masses were joined again, about 15 million years ago, these species began to move out into new territories—a mov ement that is not only still in progress but is now receiving consi derable assistance from man.The importation of plants is the primary agent in the modern sp read of species, for animals have almost invariably gone along wi th the plants, quarantine (n. 检疫；隔离；检疫期；封锁vt. 检疫；隔离；使隔离vi. 实行隔离) being a comparatively recent and not completely effective inno vation. The United States Office of Plant Introduction alone has int roduced almost 200,000 species and varieties of plants from all ov er the world. Nearly half of the 180 or so major insect enemies of plants in the United States are accidental imports from abroad, and most of them have come as hitchhikers on plants.In new territory, out of reach of the restraining hand of the natural enemies that kept down its numbers in its native land, an invading plant or animal is able to become enormously abundant. Thus it is no accident that our most troublesome insects are introduced species.These invasions, both the naturally occurring and those dependent on human assistance, are likely to continue indefinitely. Quarantine andmassive chemical campaigns are only extremely expensive ways of buying time. We are faced, according to Dr. Elton, ‘with a life-and-death need not just to find new technological means of suppressing this plant or that animal’; i nstead we need the basic knowledge of animal populations a nd their relations to their surroundings that will ‘promote an even balance and damp down the explosive power of outbreaks and new invasions.’Much of the necessary knowledge is now available but we do not use it. We train ecologists in our universities and even employ them in our governmental agencies but we seldom take their advice. We allow the chemical death rain to fall as though there were no alternative, whereas in fact there are many, and our ingenuity could soon discover many more if given opportunity.Have we fallen into a mesmerized (adj. 着迷的v. 施催眠术，迷住，迷惑）state that makes us accept as inevitable that which is inferior or detr imental, as though having lost the will or the vision to demand that which is good?Such thinking, in the words of the ecologist Paul Shepard, ‘idealizes life with only its head out of water, inches above the limits of toleration of the corruption of its own enviro nment...Why should we tolerate a diet of weak poisons, a home in insipid surroundings, a circle of acquaintances who are not quite our enemies, the noise of motors with just enough relief to preve nt insanity? Who would want to live in a world which is just no t quite fatal?’Yet such a world is pressed upon us. The crusade to create a che mically sterile, insect-free world seems to have engendered a fanat ic zeal on the part of many specialists and most of the so-called control agencies. On every hand there is evidence that those enga ged in spraying operations exercise a ruthless power. ‘The regulato ry entomologists (n.昆虫学者)function as prosecutor(n. 检察官；公诉人；[法] 起诉人；实行者), judge and jury, tax assessor and collector and sheriff to enforce their own orders,’ said Connecticut entomologist Neely Tu rner. The most flagrant (declared公然的；notorious) abuses go unche cked in both state and federal agencies.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. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. If the Bill of Rights contains。

Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death.(--11) lie long in soil: they stay in soil for a long time because they don’t break down chemically there entering into living organisms, passing from one to another in a chain of poisoning and death: the chemicals that insecticides contain are likely to enter birds and animals in food, and then pass out in waste matter from their bodies, get into the soil and are absorbed by the plants that grow on it. When birds and animals and people eat the plants, these substances again are taken into their bodies. This process goes on and on endlessly, poisoning plant and animal life alike. In short, the chemicals tend to be endlessly recycled in the food chains.

Gone are the harsh winds of winter, replaced by a gentle breeze that carries with it the promise of new beginnings. In the quiet of the early morning, one can hear the soft rustle of leaves awakening from their winter dormancy and the gentle chirping of birds greeting the dawn. It is a time when nature seems to pause, inviting us to immerse ourselves in its tranquil embrace.As the days grow longer and the sun begins to warm the earth, the landscape transforms into a tapestry of vibrant colors. The once barren trees burst forth with blossoms, painting the world in shades of pink, white, and lavender. The fields come alive with the cheerful hues of wildflowers, their delicate petals swaying in the breeze. Against this backdrop of natural beauty, one cannot help but feel asense of awe and wonder at the magnificence of the world around us.Yet, amidst the riot of colors and the symphony of sounds, there exists a profound sense of stillness. It isin the quiet moments of reflection that one truly appreciates the beauty of spring.

In its serene embrace, we find solace from the chaos of the world and discover a renewed sense of wonder and gratitude for the gift of life. As we journey through the season of renewal, may we take the time to pause, to listen, and to embrace the tranquility thatsurrounds us. For in the stillness of spring, we find the true essence of beauty and grace.。

《寂静的春天》(Silent Spring)

《寂静的春天》（Silent Spring）《寂静的春天》（SilentSpring）于1972～1977年间陆续译为中文，开首的几章曾在中国科学院地球化学研究所编辑出版的学术刊物“环境地质与健康”上登载过，全书于1979年由科学出版社正式出版。

20年后的今天，我们高兴地看到，在中国社会科学院哲学研究所吴国盛先生及吉林人民出版社的协同努力下，这本书得以纳入《绿色经典文库》再版。

我们衷心希望，这本彪炳史册的著作为中国环境保护事业带来的启迪和推动，能够继续下去。

《寂静的春天》1962年在美国问世时，是一本很有争议的书。

它那惊世骇俗的关于农药危害人类环境的预言，不仅受到与之利害悠关的生产与经济部门的猛烈抨击，而且也强烈震撼了社会广大民众。

你若有心去翻阅本世纪60年代以前的报纸或书刊，你将会发现几乎找不到“环境保护”这个词。

这就是说，环境保护在那时并不是一个存在于社会意识和科学讨论中的概念。

确实，回想一下长期流行于全世界的口号——“向大自然宣战”、“征服大自然”，在这儿，大自然仅仅是人们征服与控制的对象，而非保护并与之和谐相处的对象。

人类的这种意识大概起源于洪荒的原始年月，一直持续到20世纪。

没有人怀疑它的正确性，因为人类文明的许多进展是基于此意识而获得的，人类当前的许多经济与社会发展计划也是基于此意识而制定的。

蕾切尔．卡逊(RachelCarson)第一次对这一人类意识的绝对正确性提出了质疑。

这位瘦弱、身患癌症的女学者，她是否知道她是在向人类的基本意识和几千年的社会传统挑战?《寂静的春天》出版两年之后，她心力交瘁，与世长辞。

作为一个学者与作家，卡逊所遭受的诋毁和攻击是空前的，但她所坚持的思想终于为人类环境意识的启蒙点燃了一盏明亮的灯。

蕾切尔．卡逊1907年5月27日生于宾夕法尼亚州泉溪镇，并在那儿度过童年。

她1935年至1952年间供职于美国联邦政府所属的鱼类及野生生物调查所，这使她有机会接触到许多环境问题。

寂静的春天英文版

寂静的春天英文版Silent SpringBy Rachel CarsonIn the early days of spring, the world awakens from its slumber. Birdsong fills the air, and blossoms adorn the trees. But in the quiet corners, a sinister threat lurks, a threat that silently undermines the very foundation of life.Rachel Carson, a pioneering marine biologist and conservationist, sounded the alarm in her groundbreaking 1962 book "Silent Spring." This seminal work exposed the devastating consequences of the indiscriminate use of pesticides, particularly DDT, on the environment.The Silent WorldCarson's narrative begins with a haunting descriptionof a world gone silent, a world where the songs of birdshave been extinguished. This grim prophecy served as astark warning that the silent spring was not merely a metaphor but a very real possibility.The culprit, Carson argued, was the widespread use of synthetic pesticides like DDT. These chemicals, designed to kill insects, had unintended and far-reaching consequences. They accumulated in the environment, poisoning wildlife and harming human health.Bioaccumulation and BiomagnificationDDT, a persistent and bioaccumulative substance, accumulates in the fatty tissues of organisms. As organisms are consumed by higher-level predators, the DDT concentration increases, a process known as biomagnification. Birds, at the top of the food chain, were particularly vulnerable to the effects of biomagnification.Carson's research revealed alarming evidence of DDT's impact on bird populations. She documented the thinning of eggshells in eagles and other predatory birds, leading toreproductive failure and population decline. This discovery sent shockwaves through the scientific community and sparked widespread concern.Environmental ContaminationCarson's book also highlighted the pervasive nature of environmental contamination. DDT and other pesticides were drifting far beyond their intended targets, contaminating waterways, soil, and even food supplies. Thisindiscriminate pollution threatened not only wildlife but also human health.Carson warned of potential human health risks associated with DDT exposure, including cancer, neurological disorders, and reproductive problems. She advocated for a precautionary approach, urging a ban on the use of persistent pesticides until their safety could be fully assessed.A Call to Action"Silent Spring" became a catalyst for environmental activism. It galvanized public opinion, forcing governments and industries to confront the dangers of pesticide misuse. The book played a pivotal role in the establishment of the Environmental Protection Agency (EPA) in 1970 and the subsequent ban on DDT and other persistent pesticides in many countries.Legacy and Impact"Silent Spring" remains an enduring testament to the power of science and citizen engagement. It transformed the way we think about environmental pollution and ignited a global movement for environmental protection. Carson's legacy continues to inspire generations of scientists, conservationists, and policymakers to work towards a more sustainable and healthy future for our planet.The Resilience of NatureWhile "Silent Spring" exposed the devastating consequences of unchecked pollution, it also hinted at theresilience and adaptability of the natural world. Despite the severe impacts ofDDT, bird populations have gradually recovered in many areas, demonstrating nature's remarkable ability to heal when given the opportunity.Carson's work taught us that we are inextricably connected to the environment and that our actions have far-reaching consequences. By understanding these connections, we can make informed choices that protect our air, water, and wildlife for generations to come."Silent Spring" remains a timeless masterpiece, a clarion call to safeguard the intricate web of life that sustains us. Its message is as urgent today as it was when it was first published, reminding us that we have a responsibility to be stewards of the environment and to ensure that the springs of our future are filled with birdsong and not silence.。

[VIP专享]精读 silent spring 原文寂静的春天(同飞君)

There was once a town in the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of colour that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the autumn mornings.Along the roads, laurel, viburnum and alder, great ferns and wild flowers, delighted the traveller's eye through much of the year. Even in winter the roadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and autumn people travelled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their houses, sank their wells and built their barns.Then a strange blight crept over the area and everything began to change. Some evil spell had settled on the community: mysterious maladies swept the flocks of chickens; the cattle and sheep sickened and died. Everywhere was a shadow of death. The farmers spoke of much illness among their families. In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients. There had been several sudden and unexplained deaths not only among adults but even among children, who would be stricken suddenly while at play and die within a few hours.There was a strange stillness. The birds, for example — where had they gone Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. 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 robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.On the farms the hens brooded, but no chicks were hatched. The farmers complained that they were unable to raise any pigs — the litters were small and the young survived only a few days. The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.The roadsides, once so attractive, were now lined with browned and withered vegetation as though swept by fire. These too, were silent, deserted by all living things. Even the streams were now lifeless. Anglers no longer visited them, for all the fish had died.In the gutters under the eaves and between the shingles of the roofs, white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams.No witchcraft, no enemy action had silenced the rebirth of new life in this stricken world. The people had done it themselves.This town does not actually exist, but it might easily have a thousand counterparts in America or elsewhere in the world. I know of no community that has experienced all the misfortunes I describe. Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim spectre has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.What has already silenced the voices of spring in countless towns in America?

英语作文冰川Title: The Magnificent Glaciers: Guardians of Earth's Climate。

Glaciers, majestic and awe-inspiring, stand as silent sentinels of our planet's climate history. These immense rivers of ice, shaped by time and weather, play a crucial role in regulating Earth's temperature and sustaining life. In this essay, we will delve into the significance of glaciers, their impact on the environment, and the threats they face in the modern world.First and foremost, glaciers serve as reservoirs of freshwater, storing vast amounts of the world's water supply. As temperatures rise, these frozen giants release water, contributing to river flows and sustaining ecosystems downstream. Moreover, they act as natural regulators of global climate patterns, influencing weather systems and maintaining regional climates. Their reflective surfaces also help to cool the Earth by reflecting sunlightback into space, mitigating the effects of global warming to some extent.However, the very forces that shape glaciers also pose threats to their existence. Climate change, driven by human activities such as deforestation and the burning of fossil fuels, is causing temperatures to rise at an unprecedented rate. As a result, glaciers worldwide are receding at alarming speeds. This not only leads to the loss of freshwater resources but also disrupts ecosystems and accelerates sea-level rise, endangering coastal communities and biodiversity.Furthermore, the melting of glaciers contributes to the release of stored carbon and other greenhouse gases, exacerbating the climate crisis. The loss of ice also impacts local communities that rely on glaciers for water supply, agriculture, and tourism, leading to socio-economic challenges and displacement.In addition to climate change, other human activities pose direct threats to glaciers. Pollution, industrialdevelopment, and tourism can degrade glacier environments, introducing pollutants and altering natural habitats. Additionally, irresponsible tourism practices, such as littering and unregulated access, can further accelerate glacier retreat and damage fragile ecosystems.Despite these challenges, there is hope for the preservation of glaciers. International efforts to combat climate change, such as the Paris Agreement, aim to limit global warming and reduce greenhouse gas emissions. Furthermore, scientific research plays a vital role in understanding glacier dynamics and developing strategies for their conservation. Initiatives to promote sustainable tourism and raise awareness about the importance of glaciers can also contribute to their protection.Individual actions, too, can make a difference. By reducing our carbon footprint, adopting sustainable practices, and advocating for environmental protection, we can all play a part in safeguarding glaciers for future generations.In conclusion, glaciers embody the beauty andresilience of our planet's natural wonders. As guardians of Earth's climate, they deserve our utmost care and protection. By addressing the root causes of climate change and promoting sustainable practices, we can ensure that these frozen marvels continue to inspire and sustain life for generations to come.。

寂静的春天 silent spring 英文读后感

Silent Springby Rachel Carson“There was a strange stillness. The birds, for example—where had they gone?”“The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was spring without voices.”“On the farms the hens brooded, but no chicks hatched.”“The roadsides, once so attractive, were now lined with browned and withered vegetation as though swept by fire. These, too, were silent, deserted by all living things. Even the streams were now lifeless.”This is a strange scene described by Rachel Carson, who is regarded as “the mother of modern environmental protection movement”. Silent Spring is her representative work which lighted the fire of environmental protection in America and the whole world. Before 1960s, no books or magazines talked about things like environment and ecosystem. Such a phenomenon means that environmental protection had not come to people‟s mind and the social consciousness. Indeed, the main opinion in human society from the very past about nature is to “set war against”or “conquer” it. In fact, many of human‟s progresses are made on the base of such opinion. Rachel Carson was the first person who doubted the correctness of the belief and brought the topic under focus.In Silent Spring, Carson described a miserable village which was dying under the using of DDT. The village used to be prosperous and beautiful. “In spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of color that flamed and flickered across a backdrop of pines. Then foxed barked in the hills and deer silently crossed the fields, half hidden in the mists of the fall mornings.” She thought that with the using of variety kinds of pesticide, especially DDTs, the village suffered enormous and irreversible damage and gradually withered and died. Soon it became just like the one described in the beginning. From her fine and smooth describing, I can even feel the groan of the town. Moreover Carson also sharply pointed out that the deep-seated cause for the environmental problem is the human‟s arrogance and ignorance. So she asked people to correct the attitude toward the nature and reconsidered the developing path of human being.Carson thought that because of the antibody and differentiation, pesticides would never be completely useful. On the contrary, those more and more poisonous medicines, because of the enrichment effect, would accumulate in humans‟ body. It‟s quite sarcastic that we hurt ourselves much badly while hurting the others. Then she analyzed many poisonous components in pesticides. Those are all unfamiliar names except DDT, such as chlordane, chloronaphthalene, compound 497, etc.Those things really make me feel scared. We are on the top of the food chain, and it is such a perfect and fragile system. We human beings are just part of it and we depend on all of the creatures who stay on the lower positions. It is so hard and ridiculous to try to match the nature. ”Only in the state does man have a rational existence.” Every species have their value to be on this world. Then no one knows what would happened if we force them to disappear. For example, let‟s imagine the food chain as a meticulously made castle built by billions of little blocks and we human beings are the top one. There might be several tiny blocks on the bottomwhich you think is useless and dispensable. But what would happen if we take them away? Perhaps nothing happened, and perhaps the whole castle ruined.Destruction is always much easier than recovery, not counting those incurable ones. Humans always think that we are much cleverer than the other animals, so we become more and more conceited and firmly believe that we are the king. We didn‟t see that the nature is so magical and knows how to revenge. The pay back is much more violent and cruel. We need balance and order. The nature has its own rule. Our aim is to use it and live in harmony with it. The ecosystem is so delicate that even a tiny disturbance could lead an unexpected consequence, just like the butterfly effect.At the last chapter, some scientists came up with other ways to solve the pest problem----biotic control. There is now a strongly running tide of interest in chemical sterility. Those sterile insects are released and mate the normal ones so that they won‟t have any larva and get extinct gradually. This “solution” seems to be reasonable and helpful, but thinking about it carefully, you‟ll find that it is just another way to ruin the food chain castle. Not only spring, but also summer and autumn would be still and silent in the future.It is lucky that Rachel still kept her mind clear. She didn‟t agree with the way of conquering the nature. At the very end of the book, she wrote, “The …control of nature‟ is a phrase conceived in arrogance, born of the Neanderthal age of biology and philosophy, when it was supposed that nature exists for the convenience of man.” This sentence can be regarded as the book‟s theme topic which is widely quoted in all kinds of articles about environmental protection.Carson is a great woman and fighter. When writing the book, she was suffering from huge pain of the operation for mammary cancer. After the book was published, the widely affect brought her not honor and fortune, but fierce attack from the chemical estate. She died only one year after the book‟s publishing. On the spring of 1964, the great woman passed away, but Silent Spring made her voice never silent.The 20st century was a time that technology and economy developed rapidly, especially the 40 years after Silent Spring was published. But every spring, when flowers bloom, trees sprout, and water begins to flow, we used to recall a woman and her enduring works. We opened the window, and wonder if the spring is silent today, if it will be silent tomorrow.。

下面和小编一起来看大学精读英语三课文silent spring翻译，希望有所帮助！《寂静的春天》作者：雷切尔·卡尔森在美国中部，曾经有一座城镇，在那里，所有的生灵和环境和谐相处。

这座城镇坐落在一片肥沃的农场之中，一到夏天，白色的云彩就像花瓣一样漂浮在绿色的原野上。

秋天，五颜六色的橡树，枫树和白桦树绽放在一片松林中，狐狸在山间啼叫，小鹿静静地穿过原野。

所年以来，生长在路边的月桂树、蕨类植物和野花总是令过路的旅行者感到高兴。

即使在冬天，路边也有美丽的景色，无数的小鸟回来到这里吃浆果，还有许多干草种子从雪地露出来。

事实上，这片乡村正是以它鸟类品种的丰富和多样而出名。

当大量的候鸟在春季和秋季蜂拥而来的时候，人们也从遥远的地方来此观赏它们。

还有人会在小溪边垂钓，清凉的小溪从山间流出，被树荫遮住的小水池里有鳟鱼游来游去。

直到许多年前的某一天，第一批定居者才来到此盖房子、挖水井、修建马棚。

后来，这片乡村中有了一个邪恶的咒语：神秘的疾病席卷了成群的小鸡；牛羊开始生病、死亡。

在镇上，医生们看到病人身上出现新的疾病，感到越来越困惑。

还有几起突发的死亡事件，死因不明，死者不仅有大人，还有小孩。

还有一种很奇怪的寂静。

比如说，鸟类，它们都去哪儿了？房屋后院给小鸟喂食的点儿都荒废了，仅有的几只能看见的鸟也只是在剧烈地颤抖，无法飞行。

这个春天悄无声息。

曾经，成群结队的鸟儿在清晨快乐地歌唱；现在，这里悄无声息，笼罩在田野、树林和湿地上面的只有寂静。

曾经拥有迷人景色的道路两旁，现在长满了变成褐色的枯萎植物，好像被火烧过一样。

这一切也是寂静的，被所有的生命遗弃。

即使是小溪也是毫无生气的。

所有的鱼都死了，垂钓者不再光顾这里。

几个星期之前，一种白色的粉末像雪花一样降落在这里的屋顶、草坪、田野还有小溪。

在这个遭受过打击的地区，新生命不再诞生。
