Over 36,000 dams have been built to provide hydroelectric power, drinking water, irrigation, industrial supplies and control floods. 1.2 billion people are at risk from drinking contaminated water. If 4% of the world's military expenditures (36 billion dollars) was saved each year, all of humanity would have clean drinking water and a sanitary way of disposing waste. The Hydrologic cycle uses more energy in one day than humankind has created throughout it's entire history. Factoids
