water
Two litres a day. Many people don't touch it, but we all need to drink water. However, only 1% of fresh water on Earth is drinkable. How do we ensure that there is enough water for everyone? That's not the only one of our concerns. A falling groundwater level, overflowing rivers, and heaving dikes. The Dutch are experts in water management. Sewer, polders, and rain tanks: water surrounds us and is simultaneously a burden — and a necessity.
