Pollution can be deadly

A new study shows even short-term exposure to smog can be deadly and not just for people with heart or lung disease.

That's the conclusion from a report by the National Academy of Sciences.

The new report shows a clear link between air pollution and illnesses that can become life-threatening. Some White House officials have long-said that connection has never been proven.

The report shows kids are especially vulnerable because their lungs aren't fully developed. Dr. Bill Sears, a pediatrician, said, "The long term effect of air pollution on child health is devastating. Children do not grow as well because they do not breathe as well."

Some experts say half of air pollution comes from cars and trucks. So doctors say parents should think twice before buying a home near a busy highway.
