Nathan Runkle is the founder of Mercy For Animals, an organization that focuses on the prevention of cruelty to the billions of farm animals raised for food in the United States. Nathan's just written an amazing memoir, titled Mercy For Animals, with friend-of-the-podcast Gene Stone. The book is part coming of age story, part exposé of the animal agriculture industry, and part gripping tale of adventure and risk and strategy as a few passionate, committed young people go undercover to expose the abuses that are a regular and normal and accepted part of our meat-based food chain.
