Acid Rain

Trees and lakes all over Europe are dying.

There are already 18,000 Swedish lakes where fish cannot live and soon the Germany's Black Forests may be dead.

Modern industry produces a lot of dangerous gases. Two of the most dangerous are sulphur dioxide and nitrogen oxide. To stop pollution near factories and power stations, these gases enter the atmosphere from tall chimneys. Then they mix with water in the air. After that, the wind carries them for hundreds or even thousands of kilometres. Finally, the mixture of water and chemicals falls back to earth as acid rain.
