Bill McKibben

This series features conversations on the moral and ethical issues raised by the Occupy Wall Street movement. Bill McKibben is the author of a dozen books about the environment, beginning with The End of Nature in 1989, which is regarded as the first book for a general audience on climate change. He is a founder of the grassroots climate campaign 350.org, which has coordinated 15,000 rallies in 189 countries since 2009. Time Magazine called him "the planet's best green journalist" and the Boston Globe said in 2010 that he was "probably the country's most important environmentalist."
