1. So, is blown sand in the air a pollutant (as opposed to a natural phenomenon)? Are the aerosols from pine trees that cause the bluish haze in the Appalachians that spawned the names “Smokey Mountains” and “Blue Ridge Mountains” also pollution? And pollen? Are all naturally occurring particulates and aerosols in the air now pollutants? To be regulated by the EPA?

  2. Their method of calculation is somewhat obtuse, also their claim that 350.000 people die sooner (????? WTF) due to PM 2.5. I guess they checked all lungs of all people that ever died and checked the PM content or something?
