Bill McKibben is an author and environmentalist who in 2014 was awarded the Right Livelihood Prize, which is frequently referred to as 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 been translated into 24 languages; he’s gone on to write a dozen more books. 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 XL Pipeline, and launched the fast-growing fossil fuel divestment movement. http://enthompson.unl.edu/
