In modern world there are number of zoos all over the world. Some people believe that zoo is very useful for both animals. However some others thought that zoo are harmful and not a useful one. In my point of view, zoo has so many advantage rather than disadvantage. So I believe that zoo has more useful purposes.

From one side, the safety measure in zoo is one of the main concerns. There is lack of basic facilities in zoo to take care of animals in emergency situation. The recent survey shows that nearly 30% of zoo does not have basic facilities to help animals. The living habit of animals in zoo is also a major problem. Some animals in zoo do not know how to hunting. The survey also shows that behaviors of animals in forest are very different from the animals that are lived in zoo.

From the other side, zoo is one of the favorite tourist spot for numerous people. Every day there is an increase in number of tourist person. There is very good entertainment for whole family. Children are eager to see the animals and they can learn the behavior of numerous animals. Zoos are also used for educational purposes. It is possible for them to learn the scientific names of animals. Numbers of research are undergone in zoo to study the beading and other aspect of animals.

Furthermore, it is also a safe guard for animals from natural disaster. Nowadays due to global warming huge amount of forest and animals are destroyed. For instance, the number of polar beer is reduced from the past decade. There is large amount of polar bears are died for each year. This leads to total destruction of whole species. Alternatively, zoo tries to improve their living condition and protect the animal species from destruction.

From the above points, zoo is very essential for both people and animals. The one main concern is that the zoo should follow the international safety norms to protect the animals.
