Zoo is the place to conserve the animals in order to avoid extinction.  There are many animals that threatening to rare now. The animals need the place to continue their live. Therefore, the government builds the zoos and provides an adequate service.

                As we know, the function of the zoo is for breeding the animals and protect them. The zoo will take care of the animals, feed them, and help them to grow. However, zoo will create the animals bored and stress due to the atmosfer between their real habitat and zoo are different. For instance, pole bear has habitat in the pole. But, people bring them to the zoo. The pole bear will  not survive because the condition in the zoo is different with pole. It need a great adapatations to make the bear enjoy its life in the zoo.

                In addition, usually people utilize the zoo inproperly. They’re entertaining theirselves by visitting the zoo and then zoo will sell the tickets and performs the animals in front of people. However, sometimes people use it for education, they learn about the extinct animals.

                To sum up, as far as I am concerned, zoo should be banned because it dangers the animals and their lives. So, it is a good idea to think about the animals freedom and to let them to live in their natural habitat.
