What if I told you:
you eat 3496 litres of water
Eating water might sound strange, but you are about to discover that actually you eat loads of it, you are addicted to it, and you don’t know it.
An understanding of our water consumption can help us provide a solution to one of our
most pressing problems:
making sure there is enough water for everybody on the planet.
You can be part of that

which means that
92% of the water
we use is invisible
and it is hidden in our food!
We call this invisible water Virtual Water, a term coined
by water guru Prof. Tony Allan. The concept of virtual water
helps us realize how much water is needed to produce the
goods we use and the food we eat.
Let's discover why it is invisible.

Yes, an 8 by 40 metre water-wall!

Water is precious. But not just for drinking: water is food!
Thanks to the extraordinary work of scientists we know how
much water we need to produce the food we consume. It is
easy to see that some products such as fruit and vegetables
are more water-friendly than others.
so now we know:
most of the water we use - 92 % of it - is used in food
production. Most of this water is managed by the world’s
farmers. With the help of science and technology they have
performed greater and greater miracles in improving water
productivity – in getting more crops per drop.
can we help?
The good news is that each one of us can also make the
world a little more water secure, ready to face the needs of
our peak population future. How?
The answer lies in our shopping baskets.
The amount of meat in our diet is crucial! The average daily water consumption of a meat-eating person is 5000 litres of water per day. The average for a vegetarian is 2500 litres. In countries where there is a culture of heavy meat consumption, the advice is: one meat-free-day a week! Every little bit helps.
The type of meat we consume is crucial! Choose meat raised on grass if you can. It is normally a more sensible use of water resources, since the land often cannot be used for highly productive crop production. Meat from sheep almost always falls into this category. Agri-corporations and supermarkets do not generally fit the grass-fed livestock model. Cheap meat is usually fed on grain, corn-fed beef is the problem.
The food we waste is crucial! We are highly wasteful, particularly in the industrialized nations. In the advanced economies we throw away approximately 30% of the food we purchase. Almost a third! And with it, all the water resources we use to produce that food. It would be wise to consider whether we should be producing and buying that food in the first place, so please, do not waste!
So, do not forget:
