Should there be zoos?

I think that zoos should be kept, because we they are helpful. When we need to do a project, we need the resources. Sometimes the zoo is filled with a lot of those. When I go visit the zoo, I see a description of the animal. Some people think that putting animals is harmless to them, but I don't think that. The zoo is so helpful, that I could go and do an entire essay on the species. I totally am in the agreement of having zoos. These other people need to start realizing that the zoos are beneficial. I hope the zoos are never taken apart.
