Linda Lear and Paul Driessen talked about the impact of Rachel Carson's book Silent Spring. They responded to telephone calls and electronic communications.

Rachel Carson (1907-1964) was a marine biologist and nature writer whose writings are credited with advancing the global environmental movement. Her book Silent Spring (1962) brought environmental concerns to the attention of the American public and led to a nationwide ban on DDT and other pesticides. The book helped inspire the grassroots environmental movement that led to the creation of the Environmental Protection Agency.

Linda Lear is the author of the biography Rachel Carson: Witness for Nature. She edited an anthology Lost Woods: The Discovered Writing of Rachel Carson, for which she wrote an introduction. She has also written the introductions to reissues Rachel Carson's books The Sense of Wonder and Silent Spring.

Paul Driessen is a senior policy adviser for the Committee for a Constructive Tomorrow and the Center for the Defense of Free Enterprise. He is the author of Eco-Imperialism: Green Power, Black Death in which he argues that the environmental movement imposes the views of mostly wealthy, comfortable Americans and Europeans on the poor of other nations and the ban on DDT denies them the right to rid their countries of diseases that were vanquished long ago in Europe and the United States.
