ESC Podcast Host Mark Chenoweth interviews author and organizer Bill McKibben about the critical importance of stopping the construction of the Keystone XL tar-sands pipeline.

We're staring at what scientists say may be the biggest species extinction since the last big asteroid, except this time the asteroid is us."
