“I don’t think there’s anything wrong with abolishing zoos altogether, even if that means some species will go extinct. I don’t think non-existence is a problem for animals, if it were different, we’d be ethically obliged to bring as many sentient beings into the world as possible, and that strikes me as rather odd. Those animals that exist now should have a life as nice as possible, that’s what matters most.”
