I'm interested, after reading Omnivore's Dilemma, about what we can do to eat better, especially for the environment.
This book was interesting and had really good facts- I was especially interested in the in-depth discussions of local food and why it's not always the best option, depending on your reasons for buying it. I also really liked the explanations of different models for calculating the water consumed to grow cattle. I found these discussions useful and unbiased. However, the authors were very focused on animal suffering. I'm not in favor of animal suffering, but it's not my first concern for food and I don't believe it's morally wrong to eat meat. They were obviously hugely biased to the vegan/vegetarian diet, and their objectivity became questionable as they act as if scientific studies are questionable but accept anecdotal stories as strong evidence for their own side.
Informative, but a touch holier-than-thou. I did really like their conclusions that not everybody has to be vegan all the time, it's important to decide what you can do.
