Answer:
Animals are seen in captivity with zoos, farms, wildlife parks, aquariums, marine parks and as pets. Many groups, such as PETA, do not believe that animals should be held in captivity for any purpose. Others believe that captive breeding of animals is often the only way to protect some species from extinction. Some view zoos and aquariums as necessary for research in order to improve the lives of wild animals, while others believe that they are cruel cages.
