is one of the four classical elements along with
fire, earth and air. Water was considered cold
and moist.

Using water
Ancient civilizations came into being where the
natural conditions guaranteed abundance of water,
and in the place where they could build pockets,
dams, irrigation chanells or aqueducts.
20
An aqueduct is an artificial (man-made) channel
that is made to transport water from one location
to another.
Roman aqueducts were built all over the Roman
Empire, from Germany to Africa, and especially in
the city of Rome itself, where they totalled over
416 km.

After yearly flooding caused by the Nile, on the
river bank there remained a layer of fertile
black soil.

Life was dependent on flooding of the Nile.
Ancient Egyptians prevented their land from
becoming barren by building dams and then
irrigating it.

Water is a vital part of many metabolic processes
within the body, and significant quantities of
water are used during the digestion of food.

Deficit of water
Absence of sweet water occurs in the wilderness
places and so the poorest countries are for
example Mali, Nigeria, Chad, or Sudan.
26
The countries innumerated below have been
arranged according to the amount of water per
cubic metre a year starting with the countries
suffering from the biggest deficit are
Malta, Catarrh, Singapur, Israel, Kenia,
Algieria, Somalia etc.

hope for a better day
