Lecture 26. What falls from above: Acid rain.

Planet earth is a blue gem enveloped in a thin layer of atmosphere, which is literally the breath of life. Two major environmental problems were discussed in today's lecture: air pollution, and the role it plays in acid rain formation, and ozone depletion.

Here's a site that addresses frequently asked questions about acid rain, which was compiled by an organization called Environment Canada: Acid Rain: FAQ. To learn more about how acid rain forms follow this link to a page about Acid Rain Formation.

The good news is that there is some hope that we can do something about this during your lifetime. Here are two sites presenting a more optimistic outlook: The Clean Coal Technology Program and the Clean Air Conservancy.

Ozone was the other topic of the day. Here are some excellent sites for you to use as a resource: Ozone Reality Check, Ozone Depletion and the Flat Earth Myths, and Ozone Action Page.
