Bill McKibben, author, activist and co-founder of the global grassroots climate change organization 350.org, joins David Goodman in a public conversation. Time Magazine called McKibben “the planet’s best green journalist” and the Boston Globe says that he is “probably the country’s most important environmentalist.” In this public conversaiton, McKibben recounts his journey from journalism to activism, the three scariest numbers relating to climate change, the struggle against the Keystone XL pipeline, being arrested, and his other great passion, the Boston Red Sox. This was the inaugural event in the Vermont Town Hall public conversation series. It took place on January 31, 2014, at the Spruce Peak Performing Arts Center in Stowe, VT.
