A zoo is a place where captive animals are put on display for humans to see. The focus of most modern zoos is conservation and education. While zoo advocates and conservationists argue that zoos save endangered species and educate the public, many animal rights activists believe the cost of confining animals outweighs the benefits, and that the violation of the rights of individual animals—even in efforts to fend off extinction—cannot be justified. By bringing people and animals together, zoos educate the public and foster an appreciation of other species, supporters argued. Zoos save endangered species by bringing them into a safe environment, where they are protected from poachers, habitat loss, starvation, and predators. Besides, seeing an animal in person is a much more personal and more memorable experience than seeing that animal in a nature documentary and is more likely to foster an empathetic attitude toward animals. Some zoos help rehabilitate wildlife and take in exotic pets that people no longer want or are no longer able to care for. But from an animal rights standpoint, humans do not have a right to breed, capture, and confine other animals—even if those species are endangered. Being a member of an endangered species doesn't mean the individual animals should be afforded fewer rights. Animals in captivity suffer from boredom, stress, and confinement. Maintaining species diversity within captive breeding facilities is also a challenge. Animals sometimes escape their enclosures, endangering themselves as well as people. Likewise, people ignore warnings or accidentally get too close to animals, leading to horrific outcomes. In making a case for or against zoos, both sides argue that they’re saving animals. Whether or not zoos benefit the animal community, they certainly do make money. As long as there is demand for them, zoos will continue to exist.
