I would not miss chimps if they went extinct, though I don’t dislike them enough to advocate for it.
That said, they are deeply miserable in captivity. It’s hard not to sense the evil in the atmosphere when you see the larger primates in conventional zoos.
You have obviously never been to the Congo exhibit at the Bronx Zoo. The gorillas there are clearly quite content in captivity.
That being said, few zoos have the resources to provide such ammenities.
