I think that zoos are a good thing.
The zoo is a popular place to inspire everyday people there also great for educating young adults.
The animals are basically in there natural habitat.
When food time comes zoo keepers tie food to the trees to make the animal feel as if there hunting down there food as if they were in the wild. After a generous feed the animals slowly fall asleep in there trustworthy enclosure for a good night sleep.
Most zoos breed and help endangered animals which highly effects there extinction.
The health of the animals are one of the zoo keepers top priorities.
