Most air pollution comes from automobile exhaust and burning fossil fuels like coal. These pollutants create smog and make the sky brown. They are unhealthy to breathe. They can also hurt plants and animals. When these pollutants mix with the rain, acid rain is produced. Acid rain can increase the acid levels in lakes and, therefore, harm fish and other wildlife. It can also damage soils and ruin the metal and stone on outdoor structures.
