country. Ozone, one of the most toxic ingredients in the soupy air we all know
as smog, is a form of oxygen that even at low levels can cause health problems
such as shortness of breath, coughing, and wheezing.
This year, the nation's air got a little bit better -- but

report showed that 55% of counties with ozone monitors received an "F"
rating on air quality.
"We can point to no significant ozone improvements other
than a few lucky changes in the weather," Kirkwood says in a news release.
"We can't depend on Mother Nature to protect Americans from disease and
death caused by breathing human-made smog. It's time to fight for our right to
