Life on a Salt Marsh

Nature writer Tim Traver's new book celebrates Cape Cod's Sippewisset salt marsh through personal memoir and scientific exploration. The book is called "Sippewisset: or, Life on a Salt Marsh", and it tells the tales of the swamp, from the microscopic organisms that filter out pollution to the people who make their living off the land. We'll talk with Tim about his new book and the important role of salt marshes in the ecological cycle.
