Air Pollution is generated by some buildings, is effected by the [[wind]], and can negatively impact [[Health]] and [[happiness]] when it blows across areas where your population works or lives. Over time Air pollution levels in a [[region]] can increase and produce a haze that hangs in the air.

*Wind data map uses blue arrows to show the direction of the wind blowing over your city. Be sure to construct your [[#Sources|dirty buildings]] at the edge of your city, in the direction of the arrows.
