A study by the University of Maryland during the power plant failure last August found the skies in the Northeast experienced a 90% reduction in sulfur dioxide, the main component in soot, and a 50% reduction in smog. Air visibility increased by some 20 miles during the blackout that lasted from two to five days, differing by how quickly the plants came back on line.
Said the lead scientist, "What surprised us was not so much the observation of improved air quality during the blackout, but the magnitude of the observed improvement."
In other words, without pollution – coming above all from power plants that have been allowed NOT to install pollution equipment – we could see around us and breathe without coughing.
