Today the nation enjoys far cleaner air than it did 50 years ago when the Clean Air Act was signed into law. But it isn’t clean everywhere. In fact, the quality of the air you breathe depends on where you live, and there are huge discrepancies in air quality across states, within cities, and between neighborhoods. Why is this?

On October 10, the EPA nixed its ozone and particulate matter review panels—breaking with EPA’s use of expert science advisers for ambient air quality decisions since the 1970s and consistent with this administration’s trend of abandoning science advice.
