USA HISTORY

Detailed explanation-1: -Thirteen years later, in 1958, Carson’s interest in writing about the dangers of DDT was rekindled when she received a letter from a friend in Massachusetts bemoaning the large bird kills that had occurred on Cape Cod as the result of DDT sprayings.

Detailed explanation-2: -In 1962, Rachel Carson published her most popular book, Silent Spring. The book warned about the use of man-made pesticides, especially DDT (dichlorodiphenyltrichloroethane). DDT was a popular pesticide mass manufactured during World War II.

Detailed explanation-3: -Carson warned that pesticides like DDT-dichlorodiphenyltrichloroethane-were being sprayed excessively and indiscriminately in attempts to control crop pests. Poisons washed into waterways and moved along the food chain, threatening delicate ecosystems for birds, fish and, ultimately, humans.

Detailed explanation-4: -Carson wrote that pesticides should be called “biocides” because they killed many living things, both bad and good. Although she was alarmed by acute pesticide poisoning (like Huckins’ dead birds), she was even more concerned about the slow poisoning of plants, animals, and people from pesticides.

Detailed explanation-5: -Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972. Some countries outside the United States still use DDT to control of mosquitoes that spread malaria.
