Learn to perform photosynthesis. It's easy once you get the hang of it. There are a bunch of tutorials on WikiHow, probably. C:
Seriously, though, learn where your meat comes from. I really don't eat beef (For a number of reasons), though I'll eat chicken. But I know the sources from where they come, how they kill the animal, etc. Survival of the fittest is prevalent in nature and man has reached a point where we have many options at our disposal. We have the means to raise animals for food. And as long as it is reasonable, there shouldn't be much objection. They die so we may live, just as plants and whatnot do for them. 'Tis the cycle of life and one day we will be reduced to dust to feed nature which will in turn feed an animal that another person may eat one day. (Surrogate cannibalism yaaay)
Then again, there is nothing wrong with not eating meat. You can get proper proteins from vegetables and what not, you would just have to be mindful. It takes dedication, but if that is how you feel, do such. You must define your beliefs, mio fra'.
