As time goes by, more and more wild animals become endangered and some have already died out.
One of the major reasons is that the habitats of many wild animals are polluted or destroyed. At the same time, the food some animals mainly feed on is becoming scarce, leading to starvation. Besides, a great many wild animals are hunted for food or money each year.
All in all, human beings are fully responsible for the present situation. In order to live harmoniously with animals, everyone of us should raise awareness of wildlife protection and the government is expected to take active measures to protect animals, including passing laws and establishing nature reserves.
