Arguments are still on it whether zoos should be closed or not. Some people think it is a good to have zoos as it is the source of enjoyment and fun while other are in. But I strongly believe that zoos should be close because it causes stress to animals and mental health is suffered.
On one hand zoos are considered as the fun place for children to visit, the visitors get to experience nature and animals. However, it is also a source of research and development many researchers work on, to save endangered animals from extinction. For example: white lions and elephants were endangered and they were properly looked for and bred to prevent extinction of these species.
On the other hand there are many reasons why individual think that zoos should be closed. Animals are kept in cages for years which impact their mental health and cause stressful environment. They are meant to be free in jungle, as it is their right to freely roam. Animals got limited space with poor condition and unnatural environment which cause stress and change in behavior. For example: lions and cheetah are wild animals they are supposed to be free the captivation of these animal cause mental illness and unnatural behavior in them.
In my opinion, despite the fact that zoos are source of enjoyment and educational purpose for research but it is illegal to captivate them and put them in unnatural poor environment restricting them from their natural habitat just for the sake of some benefits.
