Least Harm Principle suggests that Humans should eat beef not vegan.

This is an interesting article, claiming that you actually cause less animal death by eating animals than plowing fields and wiping out the animal population in those fields.

I'd never really thought of it that way. All these veggie-only eating people eat this food at a price, and that price is usually killing a huge percentage of the animals living on the land that those crops are grown on. That's hilarious.
