Take a Deep Breath

Good news on the clean air front — it’s getting cleaner.   In fact, it’s been getting cleaner for a long, long time.   Don’t believe me?  Well, then go check out the new EPA Air Quality Trends that was released earlier this week.  Of the six criteria pollutants (NOx, SOx, CO, PM, O3, and Pb), the trend is continually downward.  Hazardous air pollutants (HAPs) are also on their way down.  That’s despite a growing population, growing vehicle fleet, and (until recently) a growing economy.

Almost makes me want to go out and eat a big hand full of dirt.
