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 (知更鸟), catbirds (北美猫鸟), doves (鸽子), jays (松鸦), wrens (鹪鹩), and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.

Excerpt
Why
How
What
Rachel Carson was a scientist by profession, but these lines from the opening chapter of her 1962 book Silent Spring, “A Fable for Tomorrow”, show her talent as a writer. By imagining a world without birds, she aimed to alert not only the scientific community but also the general public to the damaging effects of human activity on natural ecosystems – in particular, to the harmful use of pesticides, such as DDT. She believed that the chemical industry was knowingly causing harm to plants, animals and even humans, and wished to see pesticides used in a more responsible, limited and carefully monitored way.

Why DDT
Rachel Carson, writer, scientist, and ecologist. Rachel Carson wrote four books, but each of them in some measure changed the way we thought about ourselves and our world.
DDT,a chemical compound that was originally developed as an insecticide. It has no colour, taste or odour (气味).
After World War II, it was used extensively in agriculture and health care, and played a great role. Swiss chemist Paul Hermann Muller won the Nobel Prize in Medicine in 1948.
For dozens of years, human beings have paid a heavy price for it : a large number of birds have died out ; Germ cells have been damaged ; Various chronic diseases have appeared…
几十年来,人类为此付出了沉重的代价:大量鸟类灭绝,生殖细胞受损,出现各种慢性疾病……
Pesticides were yesterday’s gospel, but today’s disaster.
农药是昨天的福音,今天的灾难。
Para. 3
Carson urged people to make themselves aware of the facts and do something about the situation. Silent Spring contains a lot of scientific research and case studies. The book details the gypsy moth eradication programme, which killed birds, in addition to gypsy moths. Another case study was the fire-ant programme that killed cows, but not fire ants. The book also gives dozens of other examples of eradication programmes that did nothing to reduce the problems they were originally designed to solve. The 50 or so pages at the end of the book list Carson’s sources, showing how thorough and precise she was as a scientist.

Para. 4
Carson’s message was very alarming, causing a great increase in environmental awareness. Its impact was immediate and far-reaching: the use of DDT was banned and the Environmental Protection Agency (EPA) was established in the US. Silent Spring was therefore regarded as a milestone in the launch of the green movement in the Western world. It also earned Carson a posthumous Presidential Medal of Freedom and put her face on the 17-cent US stamp.

Para. 5
Silent Spring was not, however, received positively by everyone. Though Carson’s research was strong and was supported by most scientists who reviewed her work, the book quickly became a target for critics in the pesticide industry. They said that Carson did not understand the science behind her arguments because she was a marine biologist rather than a chemist. Some also said that her work was more emotional than scientific. These were attempts to damage Carson’s reputation and stop her work from influencing public policy, but she remained determined to stand by her research. Carson appeared in public and on television to defend her claims – and today, more than 50 years after it was published, the voice of Silent Spring is still ringing loud and clear.

Personally, I enjoy Carson’s book. She made a crucial but potentially difficult-to-understand subject interesting and accessible to millions of people. This is not so much because of the quality of her arguments, strong though they are, but because of the beauty and elegance of her writing. Her book not only changed the world; half a century later it remains a book that deserves to be reread today, so that we can once again feel ourselves warm to the fire of its passionate message. For unless we do listen to Rachel Carson’s warning, one day we may wake up to the strange and quiet horror of another silent spring.
