Earth Day is dedicated to supporting environmental protection and was first held on this day back in 1970. The annual event now includes a wide range of events coordinated globally in nearly 200 countries.

To celebrate Earth Day on River to River, we reached back into our archive for two of our favorite conversations from 2020.

The show begins with Vietnam War veteran and author Doug Peacock. Host Ben Kieffer talks about his work in the wilderness, tracking dangerous animals, his fight against climate change and his crusade to save grizzly bears.

Peacock is the author of “The Essential Grizzly: The Mingled Fates of Men and Bears," “Walking It Off: A Veteran’s Chronicle of War and Wilderness,” and “Grizzly Years: In Search of the American Wilderness.”

Then, a conversation with author and biologist Neil Shubin. His latest book is titled "Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA." In it, Shubin explains a new view of evolution and how the incredible diversity of life on our planet came to be.

Guests:

  • Doug Peacock, naturalist, author, Vietnam veteran
  • Neil Shubin, Robert R. Bensley Professor of Organismal Biology and Anatomy at the University of Chicago
