'It makes no sense to pay for one's pension by investing in companies that make sure we won't have a planet to retire on'

Bill McKibben is an author and environmentalist, and the founder of, the first planet-wide, grassroots climate change movement. 

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.

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 a wide variety of publications around the world, including the New York Review of Books, National Geographic, andRolling Stone. 

Bill will be joining Change:HOW 2015 via an exclusive video interview.
