Writing prompt: Should We Keep Animals in Zoos?

Student essay:
Yesterday, a topic about animals was discussed by my classmates in the English class.
Forty percent of them thought that we should keep animals in zoos. More kinds of animals will be seen and taken good care of, if they are in the zoos. However, the rest don't agree with them. In their opinions, animals have lived in the nature for a long time. They prefer living in the nature to living in zoos. They can't move around freely in the cage.
Personally, I think we can't say that two points of views are true or false. To some endangered animals, they can't protect themselves well in the nature. They will be killed for their fur or meat by other animals and people. In this case, the amount of them will become smaller and smaller. Maybe one day, they will disappear on the earth forever. On the other hand, keeping common animals in zoos may make them feel nervous. They will be in bad health.
In a word, I think it is necessary for endangered animals to protect in zoos, but other animals shouldn't be kept in zoos.
