He frames the issue of aliens in that last video very poorly. It isn't a matter of letting. The moral obligation between hunter and prey, or farmer and cattle, are very little, if any.
If we were predators and needed to eat animals to live, I'd agree.
You have not substantiated/established that we humans are hunters, nor that animals are our prey.
Need is irrelevant. We are more scavengers and hunters. Our species were great hunters during prehistory. Human actions that are prehistoric are natural actions.
