This is an important book that should be required reading (ok I hate required reading, so maybe it should be strongly encouraged reading). 
 Eating Animals contains the most detailed and horrific descriptions of factory farming I have read. It also discusses the effects of or demand for cheap and abundant meat on the ocean, the land, and the people living near factory farms. 
 A question that really made me think is "Why is it ok to eat some animals and not others?" I kept thinking of Animal Farm's "All animals are equal, but some animals are more equal than others." Why is it ok to eat a pig? It's not ok to eat a dog, yet a pig is just as intelligent as a dog, if not more so. 
 Generally, I think it is ok for people to eat animals. However, I do not think it is ok to mistreat or abuse animals. I feel like animals should be treated well, fed well, kept healthy, and killed as humanely as possible. That, unfortunately, is not the system we have.
