Bill McKibben: Currency For The Green Movement

Bill McKibben is one of the world’s leading environmentalists. In addition to his recent success leading a coalition to stop the construction against the proposed Keystone XL pipeline, McKibben heads 350.org, an international organization dedicated to raising awareness of global warming.

This week on Sea Change Radio, host Alex Wise talks with McKibben about the struggle to stop the pipeline, the impact of the Citizens United ruling on the environmental movement and what is on the horizon for him and his fellow green advocates.
