Reduce Air Pollution

Air pollution comes from many different sources such as factories, power plants, dry cleaners, cars, buses, trucks and even windblown dust and wildfires. Air pollution can threaten the health of human beings, trees, lakes, crops, and animals, as well as damage the ozone layer and buildings. Air pollution also can cause haze, reducing visibility in national parks and wilderness areas.

I feel that this graphic displays a good depiction of the causes of air pollution and  the sources that  are effected by it.  In showing different symbols and colors for the sources, transport, removal and  effects, really get to the point of how everything is effected by air pollution
