Sorry, there are no airings at this time. Please check this page for future updates.
In this talk by activist Bill McKibben at the 2012 Green Festival in San Francisco, the founder discusses his organization's "Do the Math" campaign, which seeks to build a movement that will change the terrifying math of the climate crisis. McKibben flips the idea that those concerned about climate change have extreme demands, instead pointing to the radical ideas of those who work at oil companies and make millions in the process of altering the chemical composition of the atmosphere.
