Printemps silencieux
"Silent Spring", Carson's best-known book, was published by Houghton Mifflin on September 27, 1962. The book described the harmful effects of pesticides on the environment, and is widely credited with helping launch the environmental movement. Carson was not the first or the only person to raise concerns about DDT, but her combination of "scientific knowledge and poetic writing" reached a broad audience and helped to focus opposition to DDT use. In 1994, an edition of "Silent Spring" was published with an introduction written by Vice President Al Gore. In 2012 "Silent Spring "was designated a National Historic Chemical Landmark by the American Chemical Society for its role in the development of the modern environmental movement.
