In response to a comment someone made that zoos and circuses should be outlawed: I don't know much about circuses, and I've never been much of a fan. However, our modern, well-run zoos in various parts of the world are quite often the only mechanism for preserving severely endangered species, and restoring them to the wild habitat. Only someone who is ignorant of the valuable conservation and biological studies conducted by most reputable zoos would make a statement like that. Our local zoo has been recognized as one of the best.
