　　Preserving Our Environment

　　Man is slowly polluting his environment. He dirties the air with waste gases; he poisons the water with chemical wastes; he damages the soil with fertilizers.

　　Pollution does great harm to man. As we know, air and soil are necessary to man's survival. Polluted air, water and soil make people sick and even cause deaths. Environmental pollution is becoming one of the most serious problems that mankind faces.

　　Now it's high time drastic action was taken. First, we should make the public aware of the dangers caused by pollution. Second, we should take pollution control measures to reduce pollution. Third, we should keep our pollution under control. After all, the earth is our home. We must take care of it for ourselves and our descendants. (125 words).
