We kill about 80 billion of them a year for food..
At least that's my reading of 1 Timothy 4:3
Can’t get much more primal than Genesis 1.
I can't imagine the spirit of such words carries with it the grotesqueries and indignities we're wont to inflict on our fellow sufferers. Nor for that matter the free reign over our environment. Instead I would espouse that the spirit is the maintenance of their well-being. As might a parent, or a landowner with some interest in his lot.
Genesis 1 says "I have given you every plant yielding seed ... and every tree with seed in its fruit. You shall have them for food." Likewise to the animals, "I have given every green plant for food."
