2. The Value of Water
• Water is one of the rarest and most
precious resources on our planet
• The demand for water worldwide is
increasing because of population
growth and modern lifestyle of
developed countries
• Faced with a shortage of water the right
way to act is try to consume less and
better to ensure this resource to all,
today and tomorrow
3. Apparent aboundance
not all the water can be
used!
What does it
mean?
If all water in the world filled a
5-liter bucket, usable water
would fill just a coffee
teaspoon!
4. Rational and sustainable use
To ensure continuity and safety
the habits of water consumption should be
guided
by rational and sustainable use.
HOW?
Through the respect of some simple rules:
1. Abandon the belief that water is an unlimited resource
2. Do not pollute
3. Reduce water waste
4. Optimize the use of water
5. Generalize the water reuse
5. Everyday consumption
How much water do we consume
every day?
Only for domestic purposes a
European citizen uses an average of
almost 300 liters of water a day….of
these, only 2 liters are used for
drinking !
6. What do we use water for?
Every day we use large amounts of water
for different purposes:
8. POLLUTION

9. WATER AND HEALTH
Water is the most important element necessary to
ensure that everyone obtains the universal human
right
"to a standard of living adequate for
health and well-being of himself and of
his family"
(article 25, Universal Declaration of Human Rights)
For good health, nothing else is as important
as pure water.
10. WATER AND HEALTH
Every day your body loses two and a half
liters of fluid.
In an emergency, a human can survive
several weeks without food but cannot
survive without water more than three days.
An adequate water
consumption is healthy and
keeps us vital.
11. Why is water important
for our body?
• involves assimilation of food and digestive
leading processes
• carries nutrients and oxygen to cells
• removes the waste products through the blood
and lymphatic system
• lubricates every joint in our body
• eliminate the impurities that are deposited on the
skin
• replace the liquid that we lose through breathing,
perspiration and digestion.
• helps regulate body temperature through
perspiration
• serves as a protective cushion for the brain and
spinal cord
12. Water without borders
In the world water available is more than
enough to satisfy everyone's needs, but
we should care about its extraction and
distribution
water has no borders
it is a common resource
whose protection
requires international cooperation
