No articles from me, but I do have a book recommendation. The World Peace Diet. Maybe you've read it. I made the decision to go veg before even getting halfway through the book. It covers a wide variety of issues, including both the animal rights and environmental issues...even health ones, it just doesn't go very in depth on that topic (for that, I'd say The China Study is the best, but I'm sure others will chime in with shorter articles).
