Air pollution. View of power station chimneys polluting the air. These power stations burn fossil fuels such as coal to produce electricity. This process leads to the production of dangerous gases. These include sulphur dioxide, nitrogen oxides and particles of soot. The release of these gases can have adverse effects on people living nearby. Increased incidence of asthma and bronchitis has been linked to air pollution. Another, farther reaching effect is acid rain. Here, moisture in the air absorbs the gases, and becomes very acidic. When this rain falls, the acidity damages and kills living things, most commonly trees and fish.
