Clearing the air on pollution trends

Is America’s air quality getting cleaner, or dirtier? Well while many believe it is getting dirtier because of more factories, people and cars, a new report by Steven Hayward of the American Enterprise Institute indicates otherwise. Relying extensively on EPA data, Hayward’s study reveals sharp declines in all major pollutants including carbon monoxide, lead, ozone, particulates, nitrogen and sulfur dioxide over the past 30 years. Importantly, these declines are not just in sheer volumes of pollutants spewed into the atmosphere, but also in the concentrations of these pollutants found in the air we breathe. No doubt Hayward’s study provides some clean air news we can all breathe easy about.
