More and more rain in Eastern Canada is acidic. Air pollution in the United States seems to be the reason why. It's happening in the U.S.A., too. Rain as acidic as lemon juice fell in Wheeling, West Virginia, and many lakes in New York State are dying from acid rain. Also there's acid rain in Germany's Black Forest.
Acid rain starts out as regular rain.
But when it falls through clouds of air pollution, rain changes into a weak acid. This acid is strong enough to kill trees, dissolve marble and kill whole lakes. Just cover with water and bring to a boil. Never use the stove without permission from your family. Simmer for 15 minutes.
