I disagree with the idea that zoos do more harm than good. On the contrary, zoos are beneficial for both humans and animals. Let me explain.
First, zoos are safe for animals. In the wild, poachers often kill many animsls for their valuable parts like ivory tusks of elephants. But keeping them safe in zoos, we can protect endangered species. Besides, animals are regularky fed balanced meals and can stay healthy. When they fell ill, they can be taken good care of by vets. Furthermore, sone zoos have succeeded in artificial breeding of rare animals. It will be beneficial fir the environment in the long run.
