A zoo is a place where various animals, reptiles, mammals, insects and birds are kept. Sometimes you can see rare species of animals there. Usually zoos don’t contain domestic or farm animals, but sometimes there are children’s areas with such creatures, as donkeys, mini-horses, sheep, geese, pigs, rabbits and even pheasants. These are secluded areas where children can pet and feed animals. A visit to the zoo can be both entertaining and educational. There we can learn new facts about animals’ lives. Due to quick urbanization and deforestation many species cannot live in their natural habitat anymore. That’s why zoos and reservations exist. Opinions on advantages and disadvantages of keeping animals in the zoos differ. Some people think that zoo is a perfect place for animals, as they are always fed, well-treated and live in good conditions there. Besides, people are happy to have a chance to see wild, beautiful and exotic animals in live, to learn more about their behavior and lifestyle. From the other hand, animals have to live as close to their natural habitat as possible, for example, near forests, rivers, savannahs, jungles, safari, etc. in this respect, open zoos or wildlife reserves are much better. They usually occupy vast expanses of land and let the animals move around instead of sitting in a cage. These areas are protected and supervised by the government. Thus, animal preservation, as well as pros and cons of the zoo are a frequent topic of discussion.
Every city has one or more zoos. For a while, people think that a zoo is no useful purpose. If I were faced with this issue, I would think that zoos are useful. In the following discussion, I would like to reason and provide evidence to support my viewpoint.
The first reason is that zoos are often used as places to preserve the endangered species, such as the giant pandas and tigers. It is the conservation of animals that is the most important function of a zoo. With the advances in reproductive technologies, which assist in breeding captive animals, the zoo has become the most important place for animal conservation. Thanks to zoos, certain species of animals have been saved from extinction. Such animals are bred in captivity and when they are ready to survive in the wild, are reintroduced to their original habitat - in the rain forests of Brazil, for instance.
In the second place, children can obtain direct knowledge about a variety of animals by visiting zoos. They can see what a tiger is like, hear various sounds of birds and tell one animal from another. If there is no such a place, how can they make contact with animals? They may never have a chance to see various animals even though they learn many from books. When I was a little girl, I liked animals very much, especially birds. But I could not feed them for myself, so the zoo which was located near my home was the place I went to most frequent. And I really love these places.

Zoo. Зоопарк.
