Social Justice correspondent Joanna Dafoe speaks with Bill McKibben, an influential American writer on global warming, alternative energy, and the risks associated with genetic engineering. In 2006, McKibben led a walk across Vermont to demand action on global warming; in 2007, he founded Step It Up to mobilize a day of action with global warming demonstrations across the United States. McKibben co-founded and directs the international climate organization 350.org and published The End of Nature in 1989, regarded as the first book for a general audience about climate change. He is a frequent contributor to mainstream newspapers and magazines.
