　　Many animals are in danger of dying out. As is clearly shown in the bar chart, the kinds of wild animals have decreased sharply in the past decades. With 30,000 wild animals reduced on average each year, there were only 1.5 million left till 2010.

　　There are several reasons accounting for this problem. Apart from the polluted environment and natural disasters, illegal killing is an important reason. Human beings are making attempts to hunt wild animals for fashion and a big profit, which can be seen vividly from the right picture. This has resulted in a sharp decrease in the number of animals.

　　In my opinion, it is high time for us to take quick action to protect them. A national public campaign should be launched to give animals a good living environment. In addition, the government should pass some firm laws to forbid abuse killing. Only in this way can we live in harmony with wild animals.
