Zoo officials use many arguments to support their position that holding wild animals in captivity is necessary, but those arguments are neither ethical nor necessary enough reasons to deprive animals of their natural right to freedom. Even under the best of circumstances at the best of zoos, captivity cannot even begin to measure up to wild animals' natural habitats. At zoos, animals are often prevented from doing most of the things that are natural and important to them. Zoos teach people that it is acceptable to interfere with animals and keep them locked up in captivity, where they are bored, cramped, lonely, deprived of all control over their lives, and far from their natural homes. Wild animals were made to be free, and free is what they should be.
