Water is the main
constituent of living beings and the essential element for all life forms.
Without water, no organism, whether plant or animal, simple or complex, small
or large, can live.
WATER IS THE ORIGIN OF
LIFE
Lakes and rivers but
also floodplains or wetlands (marshes and peat bogs), aquifers constitute
aquatic ecosystems.
Life appeared in the
water, about 3 billion years ago, in the form of living cells that were the
ancestors of all living things today. For 2 billion years, these primitive
cells have developed and evolved into more and more complex forms.
Thus appeared the
algae, the fish and the ancestors of the amphibians which marked the first
adaptation of the living beings out of the water.
Life was born on dry
land only 400 million years ago. The terrestrial organisms have left the water,
without being able to completely get rid of it (plants and animals consume
water, and are also made up largely of water).
WATER AND PLANTS
Plants are essentially
water. This is used to transport the materials made by the plant and the
minerals necessary for its food.
The plant draws water
and mineral salts from the soil which allow it to ensure its normal development
(nutrition, growth and reproduction).
Other exchanges of
water between the plant and its environment take place: indeed, just like
animals, a plant transpires.
WATER AND ANIMALS
In animals, water is
involved in many chemical reactions in the body, such as dehydration.
The water in the body
is used for the distribution of food substances to the cells and the disposal
of waste.
The animal body must
daily replace a certain amount of water lost through urine, perspiration and
pulmonary evaporation. In fact, water losses greater than 10% of the weight of
the animal cause serious disorders, and losses of more than 22% cause death.
WATER IN THE HUMAN
BODY
Before his birth, the
man goes through an "aquatic" phase: he bathes in the amniotic fluid.
A 3-day human embryo is 94% water. Water represents 75% of the total weight of
an infant, but in an adult, it represents only 65%.
From head to toe, we
are in water: our blood contains 83%, our skeleton 22%, our muscles 76%, and
our brain 75%.
Water vital element
Man loses an average
of two liters of water a day:
• 0.5 liter per sweat,
• 0.5 liters per
breath,
• about 1 liter in the
urine.
To compensate for
these losses, humans must absorb an average of two liters of water a day. He
finds them in drinks and food, ... If he loses 2% of his water, the man feels
the need to drink; if he loses 10%, he has hallucinations and his skin
retracts; if he loses 15%, he dies.
Water in motion
In humans, water
circulates in an uninterrupted cycle and is never stagnant: it forms a kind of
water flow in the body, and thus helps its proper functioning.
Indeed, the water
irrigates the tissues (the skin, for example), and allows the manufacture of
the cells. In addition, assisted by digestive juices, it makes possible the
digestion of food.
Water is a conductor,
it means that it has the power to drive the electrical signals emitted by the
muscles and the brain. Partly thanks to the water the man can move, speak, and
all kinds of information (heartbeat, breathing, ...) circulate between the organs.
Water also allows the
evacuation of waste from the body, thanks to the work of the kidneys.
WATER AND DAILY LIFE
We find the water in
all the daily activities: toilet, washing, evacuation of waste (WC, washbasin,
bath-tub) ... It contributes to more cleanliness and more salubrity.
Household water
consumption increases with the technical means (ease of collection and
distribution of water) and with the standard of living of the population
(purchases of household appliances, bathroom fittings, ...) .
In Europe, from 1950,
the installation of running water has developed everywhere in the city, and has
progressively reached the most remote countryside.
Drinking water at home
is a great conquest of the twentieth century and one of the benefits of technical
progress, but, used to evacuate our waste, it is polluted and must not return
to nature so as not to hinder (or even lead to the death) of the animals and
plants that live there.
WATER AND AGRICULTURE
Irrigation sees its
use spread and requires more and more water.
Livestock feeding
requires an abundant supply of water in the rearing areas.
There are many washes,
because all the equipment and the premises of exploitation must be kept clean.
WATER AND INDUSTRY
Most industrial
establishments consume water to manufacture, heat, cool, wash, etc., products
or equipment.
Water can be used to
transport goods: many barges and barges circulate on the rivers.
Water is also used to
produce electricity.
