The animals would be glad about that I'd say and they'd benefit more from that than humans themselves. I mean look at us, how the world comes to be after years pass only few realise what it means to have peace. We fight, destroy and kill others, some people just because of the sake of it, others just because they don't like something about someone. Others because if they don't, they themselves might get hurt or their families. Look how life becomes after we become worse than animals themselves...
