we re talking 2 1/2 micrones, and that is significantly smaller than a width of a human hair, for instance. so the ability for that particle to lodge itself deep in our lungs making asthmatics worse, upper respiratory issues worse is a serious concern. look at the western u.s. we have 90% of the western u.s. under drought conditions, about 38% of them classified as extreme or worse. and new mexico we have five concurrent wildfires burning out of control. this one started on tuesday this week, still at 0% containment. latest numbers over 6,185 acres have burned so far. i want you to see some of the video coming out of this area showing you the scarred structures that were impacted by this fire. you can see them just smoldering there and the fire still ongoing with 0% containment.
