I can't help you on the Biblical stance on it because of my rejection of religion.

What I can say is that any good farmer can tell you that the food we eat must be well cared for.

If there's a religious aspect to it, I suspect it would be the sacral duty of care you have to lesser beings who depend on you for survival, and for that care you feed off of them. Your duty of care should be mixed with gratitude, I suppose.
