I consider that it is better for animals to live in the wild. Firstly, there is fresh air and natural habitat where they can live in security. Secondly, they need a natural feeding without human interference. Many people think that they do the best to make animals feel good in the zoo. They build giant cages and try to make every effort so that the animals feel comfortable. I think that the animals are in terrible conditions when they are in the cages, because they do not have the opportunity to be free.
