__Causes 3__
Causes of the Shortage of Fresh Water The Number One Cause of the Shortage of Fresh Water: Global Warming. Some scientists say that global warming is the single greatest cause of the fresh water shortage in the world. A rise in average temperature in mountainous regions can alter the precipitation mix between rainfall and snowfall, with more rain and less snow. This change means more flooding and more runoff during the rainy season, but also less water held as snow and ice in the mountains for use in the dry season. These mountain glaciers or “reservoirs in the sky” are all melting. The snow/ice mass in the Himalayas, (the third largest in the world, after the two polar ice caps) is now beginning to shrink at an accelerating rate. Every major river in Asia originates in that snow/ice mass.
