I can't think of a single type of food that isn't produced without the death of one organism or another. But what do I care? I'm the top of the food chain, and the animals would TOTALLY eat humans if they were strong/intelligent enough.

How does that phrase go "I didn't fight my way to the top of the food chain to become a vegetarian". Humans have killed animals for millenia, and long may it continue. Besides, being a vegetarian isn't going to stop animals being killed anyway. *kills a badger*

As for killing for sport, hmmm, that might be a different matter entirely.
