Should we keep animals in zoo? Why or Why not

You should keep the animals in zoo so that people can take care the animals and because that's their home. And so they can eat their own food but sometimes the animals is having some emergency so they really need to leave in the zoo so they are safe and health because if they didn't leave in the zoo know one can take care of them.
