Zoos are helpful

Zoos are helpful for animals and people.
First, it is helpful for animals that are endangered.
For example, endangered animals are endangered because they have lots of predators and also they are hunted by human. So I think sending them to the artificial zoo can make them live without their enemys. And some people who think zoo are harmful say that it is too small for animals to live in, but I don't agree with this. Because there are a lot of national parks this days to make them in comfort.

Because there are many National parks designed to offer animals a comfortable place.
