It can not be denied that animals are being driven to the verge of extinction. The aim of this essay is to find out which animals are endangered, explain why we have to protect them and discuss whether they are safe enough in zoos.

A large number of animals around the world are facing with disappearance because of severe problems. For instance, in tropical, many species such as tigers are hunted for financial purpose. In Antarctica, owing to global warming, polar bears are at risk losing their home.

As you know, animals are regarded as major factors in nature since they stimulate and remain the development of biodiversity. Furthermore, they also satisfy human’s demands such as food, medicine, materials, etc...

In nowadays context, zoos are one available kind of conservation. Some zoos build natural environment for breeds, feed them well and encourage visitors to support them. Unfortunately, few ones are just keeping animals in disastrous captivity.
