I posted this last year around the same time. It's from the American Lung Association. Again this year I live in one of the worst areas in the country for all types of air pollution: Central PA. I'm glad to see PA investing in wind farms (which there are 3 within the last few years that have popped up in our areas) as a way to clean up something that really is a threat to our health, as opposed to the junk science of "Anthroprogenic Global Warming".
