When you think of smog, Los Angeles or Phoenix probably come to mind. But right now, the worst air in the country is actually hovering over Salt Lake City, and it could mean big changes for life there.
The Utah city known for its clear skies and white capped mountains is now choking on a heavy blanket of smog. The Environmental Protection Agency says this month Salt Lake City has the worst air quality in the country. Dr. Ellie Brownstein, of Utah Physicians for Healthy Environment, a civic organization, said, "If you can see it you probably don't want to breathe it. We've had a long string of this. It really doesn't give our lungs a chance to heal and do well."
