    One day in January 1958, Rachel Carson received a letter from Dukesbury, Massachusetts.
    A friend Olga Harkins who lived there complained that the plane had been sprayed with DDT (Dichloro Phenyltrichloroethane, a broad-spectrum insecticide used on a large scale worldwide in the 1950s and 1960s, won the Nobel Prize in Chemistry for those who discovered its insecticidal properties) After killing mosquitoes, she was fed in her backyard All the wild birds are dead

    .
    Carson, who has retired from the federal government to write professionally, is now considering writing a book on humans and ecology

    .
    As a result, she turned her attention to the environmental hazards of pesticides

    .
    She spent five or six years collecting data, and finally completed this work that had a huge impact on future generations

    .
    ? At the beginning of "Silent Spring", she used an imaginative perspective to depict a small town whose ecology was destroyed by pesticides, and everything was depressed and lifeless, and boldly predicted the evil consequences of human destruction of nature

    .
    The content of the second part, from Chapter 2 to Chapter 16, describes the damage caused by pesticides widely used in agricultural production to nature and human beings, and highlights the author's thinking on scientific and technological ethics

    .
    The third part is the last chapter.
    The author warns human beings to treat every life force with kindness and worrying thinking, and warns human beings to correct their irrational behaviors

    .
    When pesticides are flooded, insects are dismembered, soil is compacted, flowers and plants are poisoned, water quality is degraded, fish and shrimp are paralyzed, birds and birds are paralyzed, and animals become extinct.
    Only selfish humans are left in the world.
    Silence and so-called freedom have arrived

    .
    ? At the end of the 1960s, the United States happened to have consecutive environmental crises caused by artificial chemicals.
    The American people's trust in the government and chemical plants dropped to the lowest point in history, and people prosecuted the U.
    S.
    government

    .
    The US government initiated an investigation and in 1972 ordered a nationwide ban on the use of DDT, which has been the case in many countries since then

    .
    ? "Silent Spring" is the first book that human beings pay attention to environmental issues

    .
    Its shocking prediction that pesticides harm the human environment has triggered environmental protection all over the world

    .
    This book is still influential today

    .
    [Title] Silent Spring? [Author] [America] Rachel Carson? [Translator] LizIT, Bandage, youmeng_5? [Editor in charge] Dance with my ink? About the author? Rachel Carson (May 27, 1907-April 14, 1964), an American marine biologist, her work "Silent Spring" (Silent Spring) inspired the United States and the world Environmental protection undertakings

    .
    ? Wonderful passage? Once upon a time, in a small town in the hinterland of the United States, all things coexisted harmoniously

    .
    The surrounding crop fields are like a chessboard, lush and thriving

    .
    There are endless rice fields and fruit trees all over the mountains

    .
    In spring, the sea of ​​white flowers rippling on the green ground; in autumn, the colors of oak, maple, and birch are burning and jumping against the background of pine trees

    .
    The sound of foxes echoed in the mountains, and the silent figure of a small deer appeared from time to time in the fields, looming in the autumn morning

    .
    ? Here, the roadside laurels, viburnum, alder, ferns and wildflowers can be pleasing to tourists almost all year round

    .
    Even in winter, the roadside scenery can be called beautiful, countless birds flew up to the trees to eat plums, or pecking at the grass seed ears protruding from the white snow

    .
    In fact, the countryside here is famous for its wide variety of birds.
    After a large number of birds migrate in the spring and autumn, people will come over to see their beauty

    .
    There are also people who come to fish in the creeks here.
    The water is clear and cool, running between the hills, where the ponds are dark and hidden, and salmon can be seen

    .
    Since many years ago, the first group of residents dug wells and built houses, built barns, and settled here, there has been little change here

    .
    ? Until the vegetation here withered a lot, everything began to change

    .
    The town seems to be under a vicious curse: livestock and poultry are frequently sickened, and cattle and sheep die of diseases in large numbers.

    .
    The shadow of death enveloped the entire town

    .
    The farmers all said that the family was ill, and the doctor in the town became more and more confused about this new disease that appeared on the patient

    .
    Several people died suddenly and mysteriously, not only adults, but even children, but also some of them suddenly became ill while playing, and unfortunately died within a few hours

    .
    ? A strange silence came quietly

    .
    For example, the birds-where did they go? Many people feel confused and upset when they talk about them

    .
    The breeding shed in the backyard was deserted

    .
    The few birds I occasionally saw were dying, shaking so badly that they couldn't fly

    .
    It was a quiet spring

    .
    Once here, the morning here was alive with the beating notes of the bird's dawn chorus, robins, cats, doves, jays, wrens and other birds sang and called; now, there is no sound here, There is just silence in the fields, woods, and swamps

    .
    ? On the farm, the hens brood, but no chicks come out of their shells

    .
    Farmers complained that they could no longer raise pigs—the newborn piglets were too small to survive for a few days

    .
    The apple trees are blooming, but there are no bees buzzing around among the flowers.
    Without pollination, there would be no fruit

    .
    ? The roadside that was once so charming is now full of burnt and dead vegetables, as if it had experienced the catastrophe of a fire

    .
    In the same way, everything was abandoned, and there was silence and deserted here

    .
    Even the creek was lifeless, and the anglers never visited it again because all the fish had died

    .
    ? There are still patches of white granular powder in the drainage ditch under the eaves and between the shingles on the roof

    .
    A few weeks ago, it fell like snowflakes on roofs, lawns, fields and streams

    .
    ? The world is going through hardships.
    It is neither witchcraft nor enemies.
    The world has become lifeless and everything cannot be reborn

    .
    That's people digging their graves

    .
    Although the town is fictitious, there may be a thousand such towns in the United States and other parts of the world

    .
    I haven't heard of any place where people have experienced all the sufferings I described, but each disaster has been staged in different places, and many communities have suffered a series of different disasters

    .
    The ghost of horror has quietly arrived, and people have not noticed it, but the tragedy imagined may easily become a cruel fact that everyone will face

    .
    ? What makes the spring in countless small towns in the United States silent? This book will try to find answers

    .
    ? Chapter 2 The obligation to endure? On our earth, the history of life is the history of the interaction between living things and their surroundings

    .
    The environment, to a large extent, shapes the shape and habits of surface vegetation and animals

    .
    Judging from the long development of the entire planet, the reaction of life changing its surrounding environment is relatively small

    .
    It is only in this century that one species-human beings-has gained amazing power and changed nature

    .
    ? In the past 25 years, this power has not only grown to disturbing levels, but its nature has also changed

    .
    Among the destruction of the environment by mankind, the most worrying thing is the pollution of air, soil, rivers and seas by dangerous and even deadly materials

    .
    To a large extent, this kind of pollution is irreversible.
    The vicious circle it opens has violated the earth that feeds life, and has also invaded living organisms.
    Such damage is mostly irreversible

    .
    At present, the environment is generally polluted.
    Dangerous goods like chemicals are changing the nature of the earth like radiation, but people still know little about its harm

    .
    The strontium 90 released by the nuclear explosion will enter the air, fall back to the earth through rain or radioactive fall, penetrate the soil, enter the grass, corn or wheat that grows there, and finally enter the bones of human beings and accompany us throughout our lives until we are Die

    .
    Similarly, chemicals sprayed on farmland, forest or garden will stay in the soil for a long time, enter the organism, and spread through the organism through a toxic death chain.

    .
    Or, they mysteriously spread through groundwater, and one day they will see the sky again, and through the refining of air and sunlight, they will combine into new compounds, poisoning plants, making livestock sick, and causing those who drink the once pure well water.
    Suffering from unknown harm

    .
    As Albert Schweitzer said: "People can't even recognize the demons they created

    .
    " It took millions of years for nature to nurture all kinds of life on earth today-this rich and colorful life experience It took hundreds of millions of years of development, evolution, and adjustment to reach a state of balance with the surrounding environment

    .
    The environment vigorously shapes and guides the life it supports, and there are both dangerous and beneficial elements in the environment

    .
    Certain rocks emit dangerous radiation; even sunlight, which draws energy for all life, has shortwave radiation, which may cause harm

    .
    Over time—not years but thousands of years—life will adjust itself to balance with the environment

    .
    Time is an essential element, but in the modern world, we have no time to adjust

    .
    ? The rapid changes and new situations are not actually following the inherent steps of nature, but are catalyzed by the reckless and careless steps of mankind

    .
    The current radiation is no longer just the basic radiation of rocks, cosmic rays, and solar ultraviolet rays that existed before there was any life on the earth, but was created by human intervention with atoms

    .
    The chemicals that organisms need to adapt are no longer just calcium, silicon, copper, and other chemicals that wash out from rocks and flow to the sea, but are synthetics invented and created by humans in the laboratory-there is no natural existence.
    Of the substance
