	Description:		Earthworms are supposed to be a sign of healthy soil. But they're actually an invasive species that can even damage forests. So have we been sold a lie about worms and soil? Not exactly. The relationship between the two depends on the context. And the way we garden — or farm — can make all the difference. IDEAS producer Annie Bender unearths the complicated truth about the not-so lowly earthworm. Guests in this episode: Joshua Steckley is a political ecologist, postdoctoral fellow at Carleton University and the author of The Nightcrawlers: A Story of Worms, Cows, and Cash in the Underground Bait Industry. Peter Groffman is a professor at the City University of New York Advanced Science Research Center and Brooklyn College, with research interests in ecosystem, soil, landscape and microbial ecology, with a focus on carbon and nitrogen dynamics. Mike McTavish is a conservation scientist at a rare Charitable Research Reserve in Cambridge, Ontario. Janet Browne is a historian of science and Darwin biographer, author of a two-volume set called Darwin: A Biography.
