Look at human history we ate each other and other human species. We are not special we are not chosen by God. We are just animals that think we are special. Even being vegan has an effect on the earth destroying habitat ruining bio diversity chemicals getting into the environment.

That is not my argument at all. I never made such a universal claim.

My claim is that all animals have a right to feed themselves and as a part of that right there is a right to kill other animals. Therefore it is not more immoral for a human to kill an animal than it is for a tiger. I say that only in this context, because our biology evolved to also use meat. We can survive without it sure, but it is suboptimal. It is also true that we should be eating way less meat than we do. Therefore the immoral thing is not killing or eating animals but rather the industry around it.

In relating to other animals, there is no reason our standard should be any different than animals to one another. In relating to other people, it is reasonable to have a different standard.
