Acid rain: causes and effects

Acid deposition is a problem in many parts of Canada since emissions that contribute to acid rain can travel thousands of kilometres from their source. More than half of Canadian geology consists of vulnerable hard rock (i.e., granite) areas that offer poor natural defenses from the damaging effects of acid deposition.
