Changes

Ground Pollution is the result of unclean industry, [[sewage]], and [[Waste Disposal|garbage ]] practices within your city. Ground pollution accumulates over time, and can cause sickness in buildings over top of it, as well as polluting your water table.

Air Pollution is generated by some buildings, is effected by the wind, and can negatively impact [[Health ]] 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.
