What are the pros and cons of becoming a vegetarian?

Lately I’ve been just feeling disgusting after eating certain meats/poultry (mostly chicken). I don’t really like meat as it is, and I don’t think that it would really be hard for me if I decided to make the change.. But what are the pros and cons? Health and non-health related.

And I don’t want any stupid comments like “Well one con would be NOT EATING MEAT.” I’m not an idiot :)
