Emmett Hoops was seven when he determined to help save the nearly extinct American chestnut tree. He's 64 now, but his hope and passion are unabated. In this episode of Constant Wonder, you'll meet Emmett, but you'll also hear voices from the past: people who grew up under the leaves of the chestnut tree and who relied on its nutritious nuts—before blight drove it from the American forest around 1940. Guests: Emmett Hoops, Director for District 5 and Vice President for Outreach, New York Chapter of the American Chestnut Foundation Andy Newhouse, Director of American Chestnut Project at SUNY College of Environmental Science and Forestry Special thanks to Bethany N. Baxter for archival interviews from Appalachia conducted in 2008.
