In the second installment of our series on climate change, I talk to environmental journalist and science curator for TED Talks David Biello about his book, The Unnatural World: The Race to Remake Civilization in Earth's Newest Age. Biello argues that, culturally, we’re still prey to the false notion that there’s a divide between the human and the natural, when, in fact, we humans are dependent on the natural world for our survival and are, furthermore, affecting every corner of the world, no matter how remote. We explore this notion of the Anthropocene - the geologic term meant to define an era in which humans are having such a dramatic effect on the earth that we will leave our mark in the geologic record. Biello argues we need to take ownership of our oversized role and become better, more deliberate and thoughtful stewards of our home. Along the way, he also has lots of interesting stories to tell, from the effort to bring back the wooly mammoth to the use of garbage to generate energy in Rizhao, China.
