有关动物环保的英文短文

这个是我以前写的
The reason why we should prevent endangerment of animals is that there is a chain among all the lives on the earth and all the animals are human being’s friends. We live on the same planet. We really need to help each other.
There are so many endangered species in the world. Pandas are one of them. There are about only 1000 wild pandas in the world. What they are precious is because they have existed for about three million years and have been called a “living fossil”. China is the only country where we can find wild pandas.
