How do religious people justify raising and slaughtering animals for food?

[Whateverist]

I'm an atheist and a non-vegetarian but I can clearly see that raising and slaughtering animals for food is immoral. This is partly because of the appalling conditions under which most of these animals are raised and the fact that we are killing them for our benefit.

Do religious folks agree? If not, how do they ethically defend non-vegetarianism?

Dominionism. It's right there in the bible. Fuck all of you, I own all of it because god sez. The given instruction is so stated in the bible. I am unsure why it might be that you are uncertain about this.

Without reference to the bible (since no one should have to read that thing) it is obvious that God intended us to eat animals.  Otherwise, why would He have made them out of meat?

But I disagree with any dominion bullshit.  That might have worked when we lived in small, scattered bands.  But now that we control so much of the land we had better tend to the health of the food web.  Otherwise if global warming isn't bad enough, a greatly denuded biosphere may be.
