= Water Facts of Life  =


 * There is the same amount of water on Earth as there was when the Earth was formed. The water from your faucet could contain molecules that dinosaurs drank.


 * Water is composed of two elements, Hydrogen and Oxygen. 2 Hydrogen + 1 Oxygen = H2O.


 * Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.


 * Water regulates the Earth’s temperature. It also regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes.


 * 75% of the human brain is water and 75% of a living tree is water.


 * A person can live about a month without food, but only about a week without water.


 * Water is part of a deeply interconnected system. What we pour on the ground ends up in our water, and what we spew into the sky ends up in our water.


 * The average total home water use for each person in the U.S. is about 50 gallons a day.


 * The average cost for water supplied to a home in the U.S. is about $2.00 for 1,000 gallons, which equals about 5 gallons for a penny.


 * Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water.
