1. Lions are obligate carnivores, we're not. We do not need meat to survive (evidenced by several cultures around the world living off a nearly entirely plant-based diet for centuries), lions do.
2. What animals do isn't a good moral compass. Animals rape each other, steal, kill their children, and do all sorts of morally reprehensible stuff.
>Some animals are abused and we can work on regulation to prevent that
The best solution to stopping animal abuse is to not breed the animal in the first place. Can't abuse something that doesn't exist now, can we?
>I don't think making sure cows die by old age should be the end goal.
I never proposed that. I said we shouldn't have bred them into this miserable existence in the first place.
Why do we get to decide how long a cow should live? Why do we get to artificially inseminate a cow that cannot possibly give consent? Why do we get to take away the newborn child of a defenceless creature? Come on.
