Acid Rain

Acid rain is a great problem in many countries in the North. Many fruit and drinks – oranges for example – contain acid, but they do not hurt anybody. Ordinary rain is a little acid too. But strong acid is dangerous. Car batteries contain acid which can burn your hands and can burn holes in your clothes too. In 1979 the acid rain in West Virginia , USA, was as strong as battery acid.

Acid rain is not new. People started producing acid rain when they started building a lot of factories and power stations which burned coal and oil. When you burn them, you produce such gases as SO2, for example. The wind carries gases high into the sky. There they come together with water in the air and make acid rain, acid fog and acid snow. In Canada and Northern Europe many millions of trees have died because of acid rain from power stations and factories thousands of kilometers away.

Acid rain and acid snow poison rivers and lakes too. Fish and other animals cannot live in acid water. Sweden is the country with good Clean Air laws, but a lot of Swedish lakes are dead because of acid rain from other less clean places.

Acid rain is bad for buildings too. The acid eats into stone. Many of he worlds oldest and most beautiful buildings are in danger because of acid rain. People can clean the smoke from factories and power stations, but it is expensive. And what is more dangerous - many countries which produce the most acid rain have n laws to control pollution.
