A zoo’s main purpose is to educate people about love and interest toward various animals. Visiting a zoo is an usual way to get to know about animals well and people also learn lots of things from them. For example, a person who doesn’t know about animals well can get good knowledge and experience about them by going to a zoo. If there’s no zoo, then people should travel around many places to see different animals thus it will be waste of their time and give them a great inconvenience
Also, a zoo saves animals from extinction. As many parts of the world is being industrialized, it demolishes the environment including animals’ habitats significantly and it mainly causes animal endangerment. As a result, the number of many animals has been dramatically decreased and it is a very serious problem still. But, however, a zoo preserves them from extinction by furnishing them shelters, food and their mates. For example, crocodiles are one of the most endangered species but some species have been saved because many zoos have taken care of them by providing everything they need to live.
In conclusion, there are lots of works and purpose that a zoo has on. If there’s no zoo, again, it will be disadvantageous for both people and animals. Especially, the environmental problem will get worse and give a great difficulty for animals to live. Therefore, in my opinion, I disagree that a zoo has no useful purpose.
