Nicolette Hahn Niman never thought that she would have anything positive to say about animal agriculture. An environmental lawyer and a committed vegetarian who had seen the horrors of industrial livestock production up close, her life changed when she married a rancher and began to perceive the complexities of both animal and crop production. She's author of the book, Defending Beef: The Ecological and Nutritional Case for Meat, and we talk about the new and updated edition of the book, in which she makes the case that well-raised livestock can be part of the climate solution--and that good meat can improve human health.
