The Way We Eat: Why Our Food Choices Matter - Peter Singer & Jim Mason - I find this book to be a thorough, yet unbiased look at exactly what sorts of farming and ranching practices go into bringing a selection of foods to the table. The authors look at the food choices of three families - one eating a typical American diet, one set of "conscientious omnivores", and one vegan - and track their foods to the source. The book has a good conclusions section, and offers suggestions as to how you can best support your own personal ethics through your buying and eating habits. Even after years of reading about and studying nutrition and food sources, I learned quite a few new things. Highly recommended.
