Lebenselixier-elixir of life
Der menschliche Körper besteht zu über 70 % aus Wasser. Ein Mangel an Wasser führt daher beim Menschen zu gravierenden gesundheitlichen Problemen (Dehydratation, Exsikkose), da die Funktionen des Körpers, die auf das Wasser angewiesen sind, eingeschränkt werden.
Die Erdoberfläche ist zu circa 72 % von Wasser bedeckt, wobei Ozeane hieran den größten Anteil tragen. Süßwasser-reserven bilden lediglich 2,53 % des irdischen Wassers und nur 0,3 % sind als Trinkwasser zu erschließen
The human body contains over 70% water. A lack of water therefore leads to serious health problems in humans (dehydration, exsiccosis), because the functions of the body, which depend on the water, are limited.
Water covers 71% of the Earth's surface.[1] It is vital for all known forms of life. On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation.[2][3] Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere.
