Acid rain background information: The problem with fossil fuels is that, on combustion, they release acidic gases such as carbon dioxide. These gases are carried away by air currents, sometimes travelling hundreds of miles before they dissolve in atmospheric water vapour. The acidified vapour condenses and is precipitated as acid rain (or snow). Acid rain causes the erosion of stonework and may kill plants and trees. Some forests, such as Germany's Black Forest, may be irreversibly damaged if acid rain emissions are not diminished. Acid rain also dissolves some poisonous metals, thereby introducing their ions into the water supply and damaging the aquatic life. 400 lakes are being fishless in Norway and north- European because of these dumps.
