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.
