[Unedited] Bill McKibben with Krista Tippett

We had to cut some great segments from Krista's conversation with Bill McKibben. Here you can listen to it all, and tell us what you think of our edits from our produced show "Bill McKibben on The Moral Math of Climate Change." A conversation about climate change and moral imagination with a leading environmentalist and writer who has been ahead of the curve on this issue since he wrote The End of Nature in 1989. We explore his evolving perspective on human responsibility in a changing natural world. See more at onbeing.org/program/moral-math-climate-change/209
