First published in 1962, the book silent spring to establish

Carson accused the chemical industry of spreading disinformation and public officials of accepting industry claims unquestioningly.

In the late 1950s, Carson turned her attention to conservation, especially environmental problems that she believed were caused by synthetic pesticides. The result was Silent Spring (1962), which brought environmental concerns to the American public. Silent Spring was met with fierce opposition by chemical companies, but it spurred a reversal in national pesticide policy, led to a nationwide ban on DDT for agricultural uses,[2] and inspired an environmental movement that led to the creation of the U.S. Environmental Protection Agency.[3][4]

In 1996, a follow-up book, Beyond Silent Spring, co-written by H.F. van Emden and David Peakall, was published.[5][6] In 2006, Silent Spring was named one of the 25 greatest science books of all time by the editors of Discover Magazine.[7]
