If zoos try to replicate this, then they will have to cut out a lot of other exhibits. Let's take Denver Zoo for instance. They built a very expensive predator ridge for Lions, Spotted Hyenas, and Wild Dogs. Well, I know that it is important to have education in zoos, but why not make the whole exhibit for the endangered dogs that have only bred once and don't breed usually in zoos. I still like seeing the lions and Hyenas, but I think there should be a balance that I can't put my finger on. Does someone else have any comments or input?
