Animals shouldn't be kept in zoos
The zoos are places where the people visit wild animals and they can have contact with them.
There are many opinion about if this places are good or bad.
On the one hand, the zoos are great places for fun and learning, and of course keeps endangered animals safe from harm. They are well fed and there are other animals of their specie to relate.
On the other hands, the animals aren't in their natural habitat and they are exploited because they have to be in front of an audience and some have to do functions and that makes that they are tired.
To sum up, the zoos are good places but they should let the animals relax more and not force and try to improve their quality of life
