Abstract |
The Great Lakes region of the United States and Canada is an especially appropriate focus for a conference on acid rain in 1981 for one paramount reason: If the evidence is compelling that environmental alterations from acidic deposition could, indeed, be of the type and magnitude being alleged in other regions, then there are urgent decisions and actions needed now to prevent those effects from being expressed here. A principal conference goal, therefore, must be to review the evidence as it applies to the unaltered, or slightly altered, Great Lakes region, and to consider what new data or relationships still need documentation before mitigation or control strategies can be evaluated. |
