I don't see the logic in
any of that, to be honest.
However much you'd like to disagree, humans are still animals, no matter HOW much of the earth we take over, and no matter how "intelligent" we are. And what do animals in the "wild" go by? The food chain. Because of the way that humans have evolved and developed, and the things they've invented, humans are pretty much at the top. We've been eating meat since we were cavemen.
And not only that, but humans are designed to be omnivores. This shows via many ways; incisors and canines which are designed for tearing and biting, legs which can run fast enough to persue yet they need not be fast enough to escape, and good eyesight to pick out prey. Of course, that was then, and it's so much easier now, what with farming having developed, but those elements still remain.
Anyone ever heard the song "Meat is Murder" by the Smiths? Agree or disagree? We're
meant to eat meat, and in order to eat it, we have to kill it first - whether it's wild, from a free-range farm, or a battery farm, we still have to kill it. Ultimately, the animals that we kill are meant to be eaten by us. Why don't we have the RSPCA or PETA on our backs, taking us to court, claiming animal cruelty?
Plus, people get protein deficiencies from not eating meat. What does that tell you?
I just don't see the logic.
