Acid Rains
Every year more and more plants and animals disappear never to be seen again.
Nature is carefully balanced and if this balance is disturbed every day, thousands of species of animals draw closer to extinction.
In many lakes fish are dying. Fishermen are worried because every year there are fewer fish and some lakes have no fish at all. Scientists are beginning to get worried too. What is killing the fish?
The problem is acid rains. Acid rain is a kind of air pollution. It is caused by factories that burn coal or oil, or gas. These factories send smoke high into the air. The wind often carries the smoke far from the factories. Some of the harmful substances in the smoke may come down with the rain hundreds of miles away.
