W stands for
w a t e r
There’s no lifewithout water
THE EARTH , OUR PLANEt, IS COVERED IN WATER
BUT ONLY A SMALL PART OF IT
- A MERE 2 % - IS FRESH WATER.
Yet the distribution of water on the planet is not equal : there are areas with plenty of it, while other parts are either completely dry or with insufficient supplies.
What’s more, it has to be shared. That means : less water for more people.
10 countries alone share 60% of fresh water available on the earth
Others , like Congo and Brazil , although they have big rivers, they yet lack infrastuctures to use the water.
BLOODY WARS ARE STILL
BEING FOUGHT IN MANY
AREAS OF THE WORLD
OVER WATER POSSESSION
Everyone knows that water is the most precious resource in nature
The human body is made of water in a percentage of 65%
For this reason
it is important
to learn
how to use it.
Water is to be
used
and not
wasted
Italy is one of the
biggest waster of
fresh water in the
world. It ranks 3°
after U.S.A. and
Canada, not
having
their resources
though.
Italians consume 8 times more then British and 10 more than Dane and Swede
reducing the
availability of
fresh water unit
from 2.700 to
2.000 cubic
metres.
As it is not easy
to work out
how water should be
correctly used
without wasting it
a marker has been devised to measure
the consumption of water.
THE WATER FOOTPRINT calculates
the amount of water needed for the
production of food
How much water does a single person or a community need a year
to get enough food to feed themselves?
It depends mainly on the kind of diet you rely on. Vegetarian or meat eater?
As the agriculture needs 70% of the world available water
eating habits are essential to measure the sustainabilility of each of us
A vegeterian water footprint is about 1500-2600 litres of water a year
A meat eater water footprint is 3000-5000 litres a year
The reason for this is simple: in the food chain production, meat and its derivatives need a lot of water, especially for
fodder
Better to get
calories,
proteins and
fats directly
from plants
Can you assess
how much water
you consume
when eating ?

Freshwater is a scarce resource; its annual availability is limited and demand is growing. The water footprint of humanity has exceeded
sustainable levels at several places .
There are many spots in the world where serious water depletion or pollution takes place: rivers running dry, dropping lake and groundwater levels and endangered species because of contaminated water
Water footprint reduction at home
As a consumer, you can reduce your ‘direct water footprint’
(home water use) by installing water saving toilets, applying
a water-saving showerhead, closing the tap during teeth
brushing, using less water in the garden and by not disposing
medicines, paints or other pollutants through the sink.
What can be done?
(10 useful steps to save water)
• 1. buy local products ( 0 mile diet )• 2 eat seasonal fruits and vegetables• 3. cut on meat consumption• 4. avoid eating overfished species of fish• 5. eat biological food• 6. waste less• 7. buy products with little packing• 8. cut on food too elaborate• 9 drink water from the tap• 10 no wasting when cooking
