One possible version：
Today pollution has become serious problem to our earth. The air, seas, rivers and land have been polluted by waste or poisonous things. It dose great harm not only to human beings but also to animals.
In some places, we cannot have fresh air because many factories have the poisonous smoke send into the air. Fish die from the polluted water. It is said that strange diseases have appeared in some places because of pollution.
I hope scientists can take useful steps to solve the serious problem. In the near future, we can see the pollution be controlled and air be cleaned． On the other hand, we can keep the balance of nature.
