I think another point to add is that raising animals for food can be seen as a symbiotic relationship. If not for the development of animal husbandry, would pigs, chickens, and such be as successful (from a total population pov)? I think not. Many animals have the chance to be alive, only because they are supported by humans. This relationship is not only one-way: they are protected from predators, sheltered, and fed…
> Of course this doesn't justify mistreatment. But it puts in perspective the idea that turning vegetarian, and banning meat would be good for those animals in question. It wouldn't: they wouldn't be alive in the first place. It's highly arguable whether they are better off being "alive", when this "aliveness" is so far off what they are genetically programmed to enjoy as a normal life. For example, if an alien speci…

I assume, just like humans, other animals can adapt and even enjoy a life partly controlled and radically different from natural conditions.
I think the basis should be: are they better off than in the wild? In terms of pain, comfort and stress. And I'd argue that we can give them a better life. But, especially with factory farming, we often don't.
In your specific example of aliens raising humans. If aliens let them live in decent conditions, with some added benefits: say diseases, illnesses and poverty completely eradicated, and wars forbidden. But with the caveat that aliens do decide when you die. (Somewhat similar to Logan's run...). I think many may see it as better than our current life.
