According to a recent poll, some four in ten Americans believe air pollution is worse today than it was just a few years ago, while another three in ten say it is about the same.  What is the truth?  Well according to Joel Schwartz of the American Enterprise Institute, our air quality is better today than you might expect: “Based on the 8-hour ozone standard, the past three years have been the three lowest-ozone, or smog, years on record. As a result of these three record-low years, the ozone attainment rate skyrocketed from 57 percent of monitoring sites in 2003 up to 88 percent by the end of 2005.  Exceedances of the federal ozone standard have declined 95 percent since the 1970s, and our air quality has never been better!”
