It's been 30 years since activist Bill McKibben published his well-known environmental call to action "The End of Nature." Now, McKibben sees even more threats than he did in 1989. His new book "Falter" takes a hard look at the severe consequences of failing to act on climate change -- from devastating sea level rise to mass extinctions. The book also raises fresh concerns about the development of artificial intelligence and genetic engineering. McKibben joins us to discuss his latest work, humanity’s prospects for survival and the climate change organization he founded, 350.org.
