I'm not a vegetarian, but I am interested in increasing the amount of vegetarian meals that I eat because I'm concerned about the negative environmental impacts of the meat industry. 
I think it's a good idea for that reason as well as some of the potential health-related and economic benefits as well.
Very true - plant based proteins are a lot cheaper than buying most meat products. 
I agree, I don't think I could be a vegan though, I really enjoy eggs and kefir.
