5. Zoo

A zoo might buy, sell, breed, or trade animals, or even capture animals from the wild. The rights of the individual are not considered. Animals are often overbred because zookeepers like having a constant supply of baby animals to attract the public. Zoo patrons expect to see lively, active animals, not old, tired animals. But the overbreeding leads to overcrowding. Excess animals are sold to other zoos, circuses, or even canned hunting. The animals are acquired to satisfy the interests of the zoo.

Wildlife santury

A sanctuary does not breed, buy, sell or trade animals. A sanctuary also does not capture animals from the wild but acquires only animals who can no longer survive in the wild. These might include injured wildlife, confiscated illegal exotic pets, exotic pets who are surrendered by their owners, and animals from zoos, circuses, breeders, and laboratories that close down. A Florida animal sanctuary, Busch Wildlife Sanctuary, intentionally keeps some animals out of sight so the animals don't interact with the public.
