One possible version:

Today pollution has become a serious problem to our earth. Our air, seas, rivers and land have been polluted by waste or poisonous gases. It does harm not only to human beings but also to animals. We do not have fresh air because many factories have poisonous smoke enter the air. Fish die from the polluted water. It is said that some diseases have appeared in some places because of pollution.

I urge all the countries in the world to do something to solve the serious problem.
