I've been considering becoming a vegetarian for a little while.

My reason isn't one about the morals of killing animals, I don't give a shit about the lazy bastards.

I was thinking about it because of the huge waste of resources involved in producing meat (grain/clean water/space).

And now I have a vegetarian girlfriend which will likely cause me to eat less meat anyway.

The main problems are that I cook comunal meals with my housemates who wouldn't like it if I took away their meat. And that when I go home for the holidays my parents will really not like it.

What do I do?
