Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. This ultimately means burning less fossil fuels, which today remains the major form of power used throughout the world. You may wish to use the entire Acid Rain Revisited report or the summary as a resource for your students during your study of acid rain. When the pollutants are vented into the atmosphere by tall smoke stakes, molecules of SO2 and NOx are caught up in the prevailing winds, where they interact in the presence of sunlight with vapours to … Deterioration of forests, acidification of lakes and grounds, marble decaying, and the degradation of building and ancient monuments are the potential ecological deterioration of acid rain phenomenon [23].
