I might sound bad for saying this, but I belive zoos are here for a reason. Animals are well fed, have adequate space for living, and amuse people. Nobody is going to Africa to visit ryno. If zoos were to be closed, how many people would think those creatures on tv are cgi. I've seen enough of dumb people thinking earth is flat. If you feel bad, adopt a puppy and feel beter. I don't care but when I want to see some exotic animals I'm going to zoo, and not the nearby half the earth across rainforest.
