This infographic aims to explain the science behind breathing and what's in the air. From ozone to arsenic, we'll explore a variety of pollutants and the specific impact that they have on parts of the body. Then we'll look at a world map to identify where the best and worst air quality is in the world and, specifically, the United States. We'll look in our homes to find sources of pollution, and we'll even blast off into space to explore the air quality on different planets.
