Happily, that same diet leads to much less food poisoning, water pollution, air pollution, and global warming. And, because fewer cows, pigs, and chickens would need to be raised, there would be less suffering on factory farms and in slaughterhouses. “Six Arguments is a great description of the links between our diet and serious environmental and health problems. I hope that readers and policy makers will implement the book’s many recommendations.” Walter Willett, M.D. Professor of Epidemiology and Nutrition, Harvard School of Public Health “While there are serious differences of opinion about issues relating to the animal foods component of the American diet, the provocative policy discussions in this book should be must reading for anyone interested in the future of food and agriculture.” Dan Glickman former Secretary, U.S. Department of Agriculture “Six Arguments for a Greener Diet is a great guide to the powerful impact that our dietary choices—especially high meat consumption—have on our environmental footprint.” Robert S.
