Why did she win the Presidential Medal of Freedom and be hailed as a pioneer of the environmental movement, but her deeds were controversial?

1958, Rachel? Carson received a letter describing the sudden fall of a flock of songbirds from a branch. The author thinks that the death of birds is related to a pesticide called DDT, which was sprayed by the exterminator in the nearby swamp. It was this letter that prompted Carson to launch an investigation into DDT.

She heard that some scientists and environmentalists worry that the abuse of pesticides has done harm to fish and birds and may also pose a threat to human health. She began to inquire through the government contacts accumulated by working in the US Fisheries Agency for many years. She is curious: what makes the voice of spring silent? ?

1962, Carson published her findings in Silent Spring. This book records the fatal harm to nature and human health caused by the abuse of chemical substances. Silent Spring received rave reviews, but it was accompanied by fierce criticism? Including vicious personal attacks on the author. Why is a gentle biologist and writer so controversial? Carson's career began when she was a diligent graduate student.

There she is. John? Hopkins University studies biology while working part-time. Even so, she had to drop out of school to take care of her sick father and sister before she finished her doctorate. Carson got a part-time job in the Fisheries Bureau, responsible for writing articles for marine life radio programs. Her manuscript was well received by the public and her professional ability was appreciated by her superiors, so at 1936, she became the second female full-time employee recruited by the Fisheries Bureau.

194 1 year, she published the first book of the ocean trilogy, which combined science with lyrical meditation and described the underwater world (title: the sea around us under the sea breeze, the edge of the sea). Her exploration caused widespread repercussions. In Silent Spring, Carson paid attention to the threat of human behavior to the natural balance.
