I have to admit there is something amiss with the way we treat livestock. I am, I think, at least open to changing my mind. I do wonder though, if humans didn't eat them, would there be any cows at all?
I think there would be some. Dairy and preservation herds, but they aren't wild. They could probably survive in an area without too much competition.
I think we should at a minimum give livestock lives outside of a stockyard. There should be grass under their feet and sky over their head.
