That said cultivation is natural for us as well. Farming produce and livestock. Using other species to help isn't only for humans. Other great apes steal wolf pups for protection.
I use to work in a pig slaughter and cutting plant. I use to contemplate the hanging hogs as humans, and us some aliens that farmed humans for meat. I didn't have a problem with it.
Some animals eat other animals. That is not something for us to approve of, or not. It is simply a fact of life. I dont have a problem with it because I dont see it as a moral issue.
Bad comparisons. People point to animals to show something is natural. Not moral. He confuses the issue. It isn't immoral to kill to eat. Starvation and need are not required.
