I think that the zoo has useful purpose.

I think that the zoo has useful purpose because it can make children happy, let people see more animals that we can’t see ordinary, and provides an entertaining place for people. Every body knows the kids like to go to the zoo. We can teach them that there are still many different kinds of animals besides cats, dog, and rabbits. We can add children’s knowledge through going to the zoo. We don’t want children always play TV games, and they don’t want always being at home. The zoo is a good place to go.
We can have many interacting by the process of knowing animals in the zoo. In the zoo, we can see more animals from the whole world. We can’t see the polar bear on the road, right? We can not see the animals as common as our pets in the zoo. The zoo always has performs of animals, so it provides an entertaining place for people. To sum up, I think that the zoo has useful purposes.
