There are several other advantages and disadvantages to maintaining zoos. For example, zoos save endangered species and rehabilitate injured animals, but activists argue that humans do not have the right to keep animals in captivity.
Some of the positive aspects of zoos include educating people about animals, protecting endangered species from predators and preventing species extinction by breeding endangered species.
Opponents say it is unfair to remove animals from their natural habitats, even if it protects the animals from their predators. Although many zoos provide safe habitats for their animals, some zookeepers have been accused of abusing animals or failing to provide adequate food and shelter. In addition, some animals do not live as long in captivity as they can in the wild.
