***Note*** While terms like semi-vegetarian, pesco vegetarian, pollo vegetarian, pesco pollo vegetarian, and all related ones are discouraged...I personally think that any help towards saving animals is good help. Most people (including myself) don't think that these are real forms of vegetarianism and a follower of one of those mentioned ahead wouldn't really be a vegetarian until giving up all meats, fish, and poultry. But, like I said, any help is good help, and you can still check out what they eat and don't eat on my list below.
