How about a non-biased, concise site with over 40 well-researched pro and con arguments to the question:
Should people become vegetarian?
- In 2010, each person in the US ate an average of 57.5 pounds of beef, 46.5 pounds of pork, and 82 pounds of chicken. Vegetarians, about 3.2% of the US population, do not eat meat (including poultry and seafood). Many proponents of vegetarianism say that the meatless diet is healthier and better for the environment, and that killing animals for food is wrong. Many opponents of vegetarianism say that eating meat is natural, healthful, humane, and that people have done it for millions of years. ProCon.org's 41st website explores the pros and cons in the debate over vegetarianism.
