Air pollution has several damaging effects on the environment. It soils clothes and may even rot them. Flowers, shrubs, and trees don't grow well in places where there is too much air pollution. In addition, dirty air sickens farm animals and has been known to damage food crops. Soil erosion has decreased the land resources for growing plants, too. Further, it rusts metal and disfigures historic monuments and public buildings. Some of the statues, for example, on Notre Dame Cathedral in France have begun to deteriorate as a result of prolonged exposure to polluted air. Notre Dame was built during the Middle Ages and is one of France's most historic landmarks. Air pollution also destroys the landscape beauty this earth abounds in by hiding it behind a haze of filth. Finally, extended exposure to air pollution can also affect vision and breathing humans. Even mild doses of air pollution have been known to bring on heart attacks and lung disorders.

Moreover, peasants are eager to produce tobacco or flowers to get higher profits. Second, shortages of the water often result in poor harvests because the rapid expansion of cities and towns uses up most of the water resources. In most dry provinces, a mild drought may cause poor or no harvest.
