There is a little

problem though,

because what we

consume at home

is visible to us, but

it is only a small

bit of what we use

in total.

There are two

invisible parts.

The first invisible

part is the water

used for the

production of the

industrial products

we consume

everyday, such as

paper, cotton,

clothes. This part

amounts to

167 litres per day.

The second big

invisible part is

associated with

the production of

the food we

consume.

This amounts to

3496 litres per day

which means that

92% of the water

we use is invisible

and it is hidden in our food!
