"Air pollution now impeding photosynthesis and potentially wreaking havoc on country's food supply, experts warn."

But those measures did little to curb the smog the first time. Toxic air cloaked Beijing until strong winds blew the pollutants south. The main source of foul air in the capital comes from coal-burning factories in surrounding provinces, not from activity in the city itself, and cities in those provinces did not take the same drastic emergency measures that Beijing did. Many parts of northern China, including the provinces of Hebei, Henan and Shanxi, regularly have air quality that is worse than that of Beijing.

The National Park Service Air Resources Division in an effort to increase the public's awareness of air quality issues has developed a series of five activities for elementary and secondary schools. The activities are for grades six through eight and help teach students about Acid Rain. The lesson plan was prepared as a part of The Uplands Field Research Laboratory, Volunteer in Parks, and Interpretation of Science Project. Funding was provided by the Great Smoky Mountains Natural History Association.

Ozone stinks. People who breathe it gag as their lungs burn. The EPA classifies ground-level ozone as air pollution. Yet without it, life on Earth would be impossible. A fragile layer of ozone 25 km above Earth's surface is all that stands between us and some of the harshest UV rays from the sun. The ozone molecule O3 blocks radiation which would otherwise burn skin and cause cancer. On Mars, which has no ozone layer to protect it, solar UV rays strafe the surface with deadly effect, leaving the apparently lifeless planet without the simplest of organic molecules in the upper millimeters of exposed Martian soil.
