In short,
As we know, animals are important to us. But some of them are becoming fewer and fewer in number, such as pandas. They are in danger.
There are several reasons caused this situation. First, people cut down trees. So the land is becoming less and less. Second, the food is becoming less and less. They can’t find enough bamboo to eat. What’ worse, some people kill them for their bones and fur.
How to change this situation? In my opinion, we should plant trees. Let’s build the home for pandas. We must protect them, but not kill them. We had better tell more people that pandas are important to us. They make us happy, they are our friends. We must not buy anything made of pandas fur. No business, no harm.
In a word, we share the same with them.
