Introduction
Do you know that there are approximately a hundred million wild animals, and about twenty thousand species that die every year? Wild animals are in great danger from nature, diseases and worsening environment. The extinction of animals has become a critical problem leading us to think whether or not we should keep animals in captivity.
Body – Danger
In recent 50 years, nearly two thirds of the world’s forest has been cut down for human industry and agriculture so that a variety of wild animals find it harder to survive as usual. On average, in every 6 square kilometres of the forest, there are over 750 species of trees, 400 species of birds, 150 species of butterflies, 60 species of amphibians, and thousands of species of other plants. But with the disappearance of forests, more wild animals are deprived of shelters and food and die in large numbers.
Next imagine that you travel to Africa with the hope to see wild animals, such as rhinos, giraffes, elephants and chimpanzees, only to find nothing but the samples displayed in the museum. Underneath the display, there is the sign saying” Rhinos, the world-famous animals, existed from 500 B.C to 2014 A.D., Cause of death: Human poaching”. Looking at the animal, shouldn’t we feel guilty for human indifference to animals and heavy massacre before?
Poaching is the first reason that causes the extinction of wild animals. It’s increased at the rate of 3000 per cent over the past years. Especially, the demands for rhino horns in Africa has rocketed, because it is now valued the same as gold! Other animals like panther, Chimpanzees and Africa elephants are also the victims of human poaching.
Another reason to cause animal extinction is the climate change. The earth getting warmer rapidly, the animals that suit cool climates are forced to move and finally lose their habituates for the amazing development of industry and great increase of green-house gases.
