Silent Spring - Read the following information about Rachel Carson and the first chapter of her book, __Silent Spring__ before completing the following writing assignment:

"__Silent Spring__ is a book written by Rachel Carson in 1962. The book is widely credited with helping launch the environmental movement. When __Silent Spring__ was published, it inspired widespread public concerns over pesticides and pollution of the environment. The book documented negative effects of pesticides on the environment, particularly on birds. Carson said that DDT had been found to cause thinner egg shells and result in reproductive problems and death in many birds. She also accused the chemical industry of covering up facts about DDT and spreading disinformation. DDT was used as a pesticide to keep insects from destroying crops and and to control insect-borne diseases such as typhus and malaria. However, DDT was also found to kill many species of birds. What do you think about DDT? Is it worth using if it helps save people's lives from malaria and other diseases even if it harms the environment? How would you have felt if you saw the extinction of birds, such as bald eagles, due to the use of DDT? Would you have voted to ban DDT or would you have voted to allow its use? In your opinion, should Rachel Carson be credited with bringing environmental awareness to the forefront of American culture?"
