The Life and Legacy of Rachel Carson (start time 6:20). The book Silent Spring, published in 1962, is widely credited for setting the stage for the modern environmental movement. Its author, Rachel Carson, an unassuming field biologist and writer, uncovered how in the process of killing crop pests, chemicals such as DDT were also killing birds, fish and other wildlife.  Fifty years after Silent Spring was published, several of the worst offending toxins are off the market – at least in the U.S. – but many more persist and new ones have emerged. And they’re wreaking havoc on human health, not just wildlife. How On Earth co-host Susan Moran talks with William Souder, author of the new book On a Farther Shore: The Life and Legacy of Rachel Carson, which was just published last month to mark the 50th anniversary of the release of Silent Spring.

Hosts: Susan Moran, Joel Parker
