Less than 1% of the water available on Earth corresponds to drinking water? 
 
There are 880 million people in the world who do not have a daily access to drinking water. Millions of people, especially children, still die every year from the lack of access to clean water and adequate sanitation. 
 
It is estimated that each Portuguese spends on average 120 liters of water per day, 80% of which is used in the toilet, bath and laundry. 
 
Turning off the tap while brushing your teeth or soaping your hands can save about 16 liters a day – which corresponds to 11 thousand liters of water per person every year.
