*Clean air is our constitutional right in Pennsylvania!* Here's a full recording of the PGH Clean Air Rally at the Allegheny County Courthouse in Pittsburgh, PA on March 20, 2018. Our air quality is horribly foul in Pittsburgh due in part to frequent weather inversions trapping poorly regulated industrial emissions (see frequent stench reports on the SmellPGH app: www.cmucreatelab.org/p…/Smell_Pittsburgh) The rally event was listed on Facebook here: www.facebook.com/events/214535712617712/ . Organized by PennEnvironment and the Breathe Collaborative. From the event listing, "On the first day of spring, Pittsburghers are ready to open their windows, get outside, and enjoy the great weather. Unfortunately, the air outside their windows is some of the most dangerous in the country-- in the top 2% of counties for cancer risk from air pollution. Join PennEnvironment, the Breathe Collaborative, health professionals, and concerned Pittsburghers as we rally for the clean air we deserve. Because cancer shouldn't be the cost of living in the "Most Livable City.""Event photos are gathered at: https://www.flickr.com/…/72157692936624…This video is a part of the INVERSION Documentary project: http://inversiondoc.com .
