Manitowoc county, along with Sheboygan and Door Counties have received “F” grades from the American Lung Association for their air quality, due to ozone pollution. The ozone pollution is largely created by the millions of people living in Milwaukee and Chicago, along with businesses operating factories and plants. The bad air made its way up the Lakeshore due to the ozone weighing twice as much as normal atmospheric air, causing it to settle at he lowest point, which is along the lakeshore. As far as a solution, cutting down on transportation can be hard in major cities, but more efficient ways of traveling, like taking the bus or train, can help.
