This morning on This Green Earth, Chris and Nell speak with Earl Swift, author of the book: "Chesapeake Requiem - A Year with the Watermen of Vanishing Tangier Island". The book chronicles the lives of crabbers and oystermen residing on a small island in the middle of the Chesapeake Bay. It's a story of an island that is undergoing physical, biological and economic loss and what residents believe should be done to save it.
