Life, both animal and plant, is impossible without
water. Without water men die of dehydration About 70% of
the human body is water. Of the total surface of the earth,
75 % is water and just below the surface of the land in most
areas there is a saturated layer known as the water table.
Animals and plants have large percentages of water in their
make-up and some animals regulate their movements
according to the water sources.
If there is no water there can be no life. The moon is
a sterile desert because there is no water in it. It is to be
remembered that it was water that determined the location of
human settlements and without the Nile the Egyptian
Civilization would not have developed The Nile provided
the Egyptians facilities for irrigation and transport. As
Herodotus said, Egypt is the "Gift of the Nile".
The urban man rarely thinks of the importance of water.
When he needs water, all he has to do is to turn on the tap.
The only time the urban folk become aware of the importance of water is when there is a drought and their water
supply is regulated. If water rationing becomes too drastic.
they may find themselves in a worse position than the rural
man who may have a steady supply of water from his well.
Imagine a day when the taps ran dry: Mr. Townsman
would have found life intolerable. He could not brush his
teeth, have his shave or could he have his bath in the
morning. After lunch, he would have had a very difficult
time trying to wash up. He might have used cloth to wipe his
crockery. He could not wash his car. At the end of the day,
however, our Mr. Townsman would have realized that
water is precious and he should not be a water-waster.
Scientists find water the most fascinating fluid in the
world because of its versatility and usefulness. Electricity is
generated by the force of running water. Unlike other
substances, water expands when freezing takes place. In
ancient Rome snow was used to pack prawns and meat. Ice
is used for refrigeration. Water is converted into steam and
used as power.
Whatever man eats is dependent on water for its growth.
Water can convert whole, barren tracts of land into
luxurious, rich and fertile regions, through the use of
irrigation. In parts of Spain, diminishing quantities of rain
have caused fertile land to dry up in the past years, creating
barren deserts. This is turn has caused many men and their
families to move to new places.
Most of us who take our daily supply of water for
granted. may not be able to fully appreciate the importance
of water. Many have perished through lack of water.
Military men know that the most effective way of
subduing any city or fortress is to cut its water supply.
