Bill McKibben is an author and environmentalist who in 2014 was awarded the Right Livelihood Prize, sometimes called the “alternative Nobel.” His 1989 book The End of Nature is regarded as the first book for a general audience about climate change, and has appeared in 24 languages. He is the author of more than a dozen books, including his latest, Falter: Has the Human Game Begun to Play Itself Out?, The End of Nature, Oil and Honey, Wandering Home, and Deep Economy. He is a founder of 350.org, the first planet-wide, grassroots climate change movement, which has organized twenty thousand rallies around the world in every country save North Korea, spearheaded the resistance to the Keystone Pipeline, and launched the fast-growing fossil fuel divestment movement. Foreign Policy named him to their inaugural list of the world’s 100 most important global thinkers, and the Boston Globe said he was “probably America’s most important environmentalist.” A former staff writer for the New Yorker, he writes frequently for a wide variety of publications around the world, including the New York Review of Books, National Geographic, and Rolling Stone. He is a scholar in residence at Middlebury College and lives in Ripton with his wife, the writer Sue Halpern.
