OH yea, those are horrible. I don't much like zoos either, especially for more intelligent animals like apes and elephants. They shouldn't be allowed to keep them isolated, and like in the case of this chimp, on display when they obviously don't like it.
I wonder how necessary zoos are, in a way. I know that some of them are trying to keep some animals from going extinct, but if the future of the species is just for all the individuals to be confined, it may not be worth it.
