About 70% of the human body is water.
Oceans cover about 75% of the Earth, but ocean water is salty. Therefore most of the water in the world is not drinkable.
Groundwater may be drinkable, but it is not easy to find groundwater that is clean and safe to drink.
If water drips from your tap every 10 seconds, you will waste about 315 litres of water a year—enough to fill two baths! Having a bath uses about twice as much water as taking a shower.
Having a shower instead of a bath can save up to 400 litres a week.
