Humans can live about a month without food but only a few days without water. Because 70 percent of the human body is water, weight loss in some quick diets is dramatic due to water loss. Of all the water globally, only about 2.5 percent is fresh, and two-thirds of this is locked up in glaciers and ice caps. Nobody knows how much water is underground or in permafrost. All life on earth is sustained by a fraction of one percent of the world’s water. If a five-liter jug (about 1.3 gallons) represented the world’s water, the available freshwater would not fill a teaspoon. |
