Should animals be kept in zoos?

It is said that Zoos are the animal prisons, due to the fact that they start living in a limited space just with the purpose of being displayed to people, eating what carers decide… That is, being mistreated psychologically and physically.

Although, having wild animals near us is useful to improve our knowledge and to satisfy our curiosity, we know that animals suffer, since they have emotions and feelings. They can get depressed, put on weight, since they cannot move as they would like to do…

It is a fact that animals have to live in the animal kingdom, because the animals from zoo are not household pet such as a dog or a cat, so they must not be in captivity, and specially not animals who are endangered.

Nevertheless, from my point of view there is something worse than Zoos, and it is the circus, where lions, tigers, monkeys, etc. are mistreated, incarcerated into grilles less spacious, and at time, without food for a long time, given that it is their method to teach, letting them into the cages without food or mistreating physically. And this is getting worse and worse, since tamers try to improve their tricks with animals, what suppose a lot of negative consequences to these specimens.

So, definitely, I consider that Zoos are the animal prisons. For this reason, we should change our mind and be always us who should visit wild animals in their natural space, being us inside a cage.
