Pollution decreases rainfall

Air pollution is severely diminishing rainfall in Chinese mountains, researchers have found. The same effect is probably causing water shortages in many other highly polluted areas that depend on the nearby hills for their water. Given strong pollution, China is probably the best place in the world to study this relation." The Scientists say. The situation should be attached importance, after all, environment is very essential for the human life!
