2. There was a strange stillness. Where had the birds gone? I was a spring without bird voices. Only silence lay over the fields and woods...
Rachel Carson was a scientist, but these lines from her 1962 book Siln Spring show her talent as writer. By imagining a world without birds, she aimed to warn the scientific community and the general public of the damaging effects of human activity on ecosystems-in particular, of the harmful use of pesticides（杀虫剂）,such as DDT. She believed that the chemical industry was knowingly causing ham to plants, animals and even humans, and wished to see pesticides used in a more responsible, limited and carefully monitored way.
Silent Spring contains a lot of scientific research and case studies, which proves some progirammes did nothing to reduce the problems they were originally designed to solve. And the 50or so pages at the end of the book list Carson’s sources, showing how thorough and precise she was as a scientist.
Carson’s message has caused a great increase in environmental awareness: 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 green movement in the Western world.
Silent Spring was not, however, received positively by everyone. Though supported by most scientists, the book quickly became a target for critics in the pesticide industry. They said Carson did not understand the science 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.
Personally, I enjoyed Carson’s book. Today, more than 50 years after it was published, the voice of Silent Spring is still ringing loud and clear.
