70% of the world's surface is covered by water, 97.5% of that is salt water.
Only 2.5% of that is freshwater, almost 68.7% is frozen in ice caps and glaciers.
Only 1% of the total water resources on earth are available for human use.
Up to 30% of fresh water supplies are lost due to leakage in developed countries, and in some major cities, losses can run as high as 40% to 70%.
About 90% of sewage and 70% of industrial wastes in developing countries are discharged into water courses without treatment, often polluting the usable water supply.
Water is a limited resource. What each of us does in the world, how we live, does make a difference. As we learn the value of clean, safe water and how scarce it truly is, we can take steps to protect it and to get it to people who lack access today.
Did you know that neearly 1 billion people, mostly in the developing world, have no access to safe water? More than double this number - about 2.4 billion - have no access to any form of improved sanitation facilities. They could use your help to get it.
