why do zoos exist

I think that zoos should exist because animals cant survive in the wild. They helpkeep them safe and they stop the animals from being endangered.

animals cant survive in the wild because people go and hunt for animals and eat them. Animals kill each other like tiger eats deer and predators liketigers, lions, cheetahs and sharks eat prey like deer, fish and seals. 

zoos keep the animals safe. they give them food and water and a cage and a bed and keep them away from predators. and if they are sick they will take them to the vet. 

zoos stop animals from being endangered. The zoos encourage them to have babies.

I think that animals should live in a zoo to be out of danger.
