What about if someone were starving and they needed to eat a human to survive? (Because there wasn't anything else, shipwreck, etc)
You're trying to apply the same standards to animals as to humans with respect to killing them being morally wrong, but then you make an exception that seems to place humans into a completely different category again. I don't like your exception because things are basically never that clear-cut... there's always another way. If you want to be so absolute about the morality of killing, then stick to it and don't make exceptions. If you don't want to consider animals as food, then don't consider them food, even if it means starving to death. Just as I don't think I would ever consider another human as food, even if I'm starving to death.

Yeah, what about it? I don't understand the relevance of the thought experiment.

Why can't I consider them food when there is no other option? Why can't I try to preserve animal life as much as I can, unless my very own suffering and death are at stake?
How is it so controversial to simply say that we should avoid suffering so long as we are not sacrificing our own life? If I'm well off and healthy and have everything I need to survive, then the suffering caused by my killing an animal seems super unnecessary and pointless, no? But that same act (killing and consuming the animal) when I need to do it to survive is _not_ unnecessary or pointless, thus rendering it not immoral. That's all.
