  • Learn about air pollution and how it can affect our health and environment.
  • Compare key air emissions to gross domestic product, vehicle miles traveled, population, and energy consumption back to 1970.
  • Take a closer look at how the number of days with unhealthy air has dropped since 2000 in 35 major US cities.
  • Explore how air quality and emissions have changed through time and space for each of the common air pollutants.
  • Check out air trends where you live.
  • Users will also be able to share this content across social media, with access to Facebook, Twitter, Pinterest, and other major social media sites.
