TEXT
Pollution is neither a local nor a national issue. Air and water pollution cross the borders of countries so often and in such large quantities that it has become an international problem. This is the case of acid rain, which travels for hundreds or thousands of kilometres in the air to kill forests , aquatic life and destroy buildings in countries far from the country which has produced it.
To understand what acid rain is and how it travels long distances , imagine a factory in Britain.The factory needs energy for its manufacturing, so it burns oil and coal. These fuels have a high Sulphur (S)******* which turns into Sulphur Dioxide(SO) after the burning of oil or coal. The Sulphur Dioxide goes up from the factory chimney into the air.
