On the Precipice
Sometime in the near geological future, the landscape of life on earth as we know it will be transformed. It\u2019s a mass extinction, and it\u2019s only happened five times before in Earth\u2019s history. There have been severe ice ages, perplexing loses of oxygen from our oceans, massive volcanic eruptions, meteor impacts. And now, we\u2019re on the precipice of a sixth mass extinction... and it\u2019s nothing like our planet has ever seen before. In Season 8\u2019s final episode, producer Miles Traer dives into the sixth mass extinction: Are we in it? What can the previous mass extinctions teach us about what\u2019s going on today? And how is it going to affect not just our lives, but the long term trajectory of human evolution? Paleobiologist Jonathan Payne takes us back into the geologic past and searches for biological patterns hidden in the rock record. In the previous moments of ecological chaos, Payne finds a surprising trend that no longer holds true today. Then, biologist Rodolfo Dirzo takes us into the heart of complex ecosystems to find out why large animals are so crucial for their health and survival. Based on experiments in the tropics and in East Africa, he shares what he\u2019s seen when those large animals disappear. Generation Anthropocene is supported by Stanford\u2019s School of Earth, Energy & Environmental Sciences and by Worldview Stanford.\nLearn more about your ad choices. Visit megaphone.fm/adchoices
