The fact is if you didn’t exist then you wouldn’t care either way, so it’s a moot argument. The fact that you do exist changes that, not excuses it. Or in other words: we are not doing other species a favour by eating them.
It’s also worth noting that many of the species we far isn’t the natural evolution of that animal. They’ve been bread to be fatter, or more docile etc. Many of the species suffer from health issues due to breeding that their natural cousins do not. The reason a lot of these animals seem suited to farming is because man has bread them that way. This isn’t doing these animals a favour either. It’s purely for man’s own benefit.
