This season has been all about the mutual impact birds, humans and nature have on each other. To close it out, Bill McKibben joins Tenijah for an honest chat about the future, nearly 35 years after his book debut, “The End of Nature” first sounded the alarm about climate change. He also talks about his organization, Third Act, that encourages fellow Baby Boomers to be leaders and allies to younger generations, as well as the most vocal in the fight for change — all while knowing they may not be around to see the full extent of its destruction.
