6.Insufficiency of Water

In my previous entry, I have listed theInsufficiency of Resources, Water and Food,Rapid Global Warming and theUsage and Disposal of Radioactive Productsas the 3 main environmental problems and gave a brief explanation on them.

This time round, I would like to write about the "Insufficiency of Water". Water makes up 75% of the body for new-borne babies, 70% for children and 60-65% for grown-ups. Water is one of the necessities required for the survival of human beings. On average, one would die within 4 to 5 days without any water. However, our supply of water is continuously falling. The vice-president of the World Bank once said, "If the wars of this century were fought over oil, the wars of the next century will be fought over water."

I would like to present the following data on insufficiency of water.

Fresh water suitable for human use is only 0.78% of the available water on earth.

Fresh water that is easily accessible is only of 0.01%.

Details of water available on earth

From UNESCO, "WORLD WATER RESOURCES AT THE BEGINNING OF THE 21ST CENTURY"
http://webworld.unesco.org/water/ihp/db/shiklomanov/summary/html/summary.html

Humans uses a significant amount of water that is equivalent to about 10%
of the volume of water that flows from river to the sea.

From UNESCO, "WORLD WATER RESOURCES AT THE BEGINNING OF THE 21ST CENTURY"
http://webworld.unesco.org/water/ihp/db/shiklomanov/summary/html/summary.html

Water required by humans is expected to increase by 30% from that of 2000 by 2025.

Human's water consumption

From UNESCO, "WORLD WATER RESOURCES AT THE BEGINNING OF THE 21ST CENTURY"
http://webworld.unesco.org/water/ihp/db/shiklomanov/summary/html/summary.html

1,300L of water is consumed to produce 1kg of wheat and
15,000L of water is consumed to produce 1kg of beef.

Volume of water consumed upon production

From Wikipedia
http://en.wikipedia.org/wiki/Virtual_water

By 2025, 1 800 million people will face absolute water scarcity

By 2025, 1 800 million people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under stress conditions.

From Data of Food and Agriculture Organization of the United Nations(FAO)
http://www.fao.org/nr/water/issues/scarcity.html

Water is the next most important necessity to human beings after air. Nevertheless, we are facing a serious problem of scarcity of water supply. It would not be an overstatement to say that this is a life threatening environmental problem.
In my next entry, I would like to write about 「Insufficiency of Food」.
