Water has become so rare that henceforth we will be calling it blue gold.

We do not notice its rarity since it is easily available in our regions.
In spite of all that, there is an urgent need to follow some simple actions to reduce our consumption, since while we brush our teeth, we use up 12 litres of water per minute if we let it flow and keeping the water running while shaving uses up 18 litres.

WeeDoo's suggestion:
In addition to not leaving the water flowing, save hot water as much as possible, you will reduce, in a significant manner, your energy expenses.
