Assignment
Nowadays, due to a series of bad human activities, more and more animals are losing their homes.
Faced with such a situation, what can we do to protect them
Write a short passage to present your ideas.
Assignment
Many animals are facing the danger of extinction, because the environment that they are living in has been destroyed greatly. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat. Based on the situation, some urgent measures should be taken.
First of all, some relative laws should be improved. There are obvious shortages in laws about protecting them and the according punishment is not severe enough. Moreover, people’s awareness of protecting wild animals should be raised. Furthermore, the government departments should also bear their responsibilities.
Animals are our best friends and we human beings should live in harmony with them so as to achieve the goal of preserving animals.
