The math is simple: the fossil fuel industry has five times the amount of coal, gas and oil that even the most conservative governments know is safe to burn. Left to their own devices, they’ll push us past the brink of cataclysmic disaster and life as we know it will be irrevocably altered forever - unless we rise up and fight back. In November 2012, best-selling author and environmental activist Bill McKibben and 350.org -- the organization he co-founded -- hit the road to raise awareness of this terrifying math and build a movement to challenge the fossil fuel industry. Do the Math takes us inside that tour, following McKibben as he delivers an astonishingly clear breakdown of the facts -- and the stakes -- to more than 25,000 people at sold-out shows in 21 cities across the country. The film serves as a much needed correction to industry spin, and shows how an unprecedented global movement is rising up to keep CO2 emissions down. Highly recommended for courses that look at climate science, geography, environmental policy, corporate influence, the costs of mass consumerism.
