With the development of the modern cities the country sides disappear. Unfortunately, in this way many wild animals are losing their natural habitats. As a consequence of urban extension their natural environment is destroying. Many species are now endangered because of the illegal hunting. Some wild animal such as tigers or lions are the target of hunters who want to sell their precious fur. What is more, there are a lot of people who love wearing shoes made of crocodile leather or the jewelry made of elephant's tusks. The other problem is the wooden cut which caused that other species of animals are got rid of their natural habitats. It may results in ecosystem's catastrophe.
Moreover, there is also a problem of testing cosmetics on living animals. Many species such as rabbits or mice are kept in laboratories to be guinea pigs for experiments. There are some international organizations which deal with illegal hunting or unreasonable tests on living animals. WWF is an example of organizations, which takes care of wild animals.
