Acid rain harms life in rivers and lakes.


Industrial burning of coal and other fossil fuels releases gases which contain sulphur and nitrogen oxides.These combine with atmospheric water to form acids.
When this rain falls into water bodies it significantly lowers the pH of these water bodies. Most life forms can tolerate a very narrow range of pH. The low pH kills off fishes insects and affects aquatic plant life too.
Aquatic ecosystems are harmed by acid rain often irreversibly so.
Acid rain has eliminated the brook trout in some lakes, streams, and creeks in geographically sensitive areas, such as the Adirondack Mountains of the United States.
