Air quality is a global issue. Currents of air waft gaseous and particulate pollutants from region to region, country to country, and even continent to continent. Emissions from human activities, sunlight, weather, pollution from far away, wildfires, and wind-blown dust can all affect air quality. And it can change from day to day or even hour to hour. Addressing this global issue requires a global effort. And that effort is in the works.
