Tony Hiss is the author of fifteen books, including the award-winning The Experience of Place. He was a staff writer at The New Yorker for more than thirty years, was a visiting scholar at New York University for twenty-five years, and has lectured around the world. In this episode of Nature Revisited, Tony discusses his latest work Rescuing The Planet - Protecting Half The Land To Heal The Earth. Covering topics including the vast Boreal Forest, global animal tracking, the origin of the Appalachian Trail, and various conservation initiatives and the people behind them, Tony offers a broad perspective of the Earth's biosphere: its land, its elements, its plants and animals, its greatest threats--and what we can do to keep it, and ourselves, alive.
