Did you know that it takes 140 liters of water to produce a standard cup of coffee – without milk? This is virtual water footprint includes the H20 used to irrigate and process the coffee beans and package, ship and distribute the coffee to our supermarkets. Unveiled in mid 2011, Waving Wall is a visual representation of the vast journey water takes, as well as the amount of water used in the production of certain products, and the average water usage of an individual. The wall features many displays that show the amount of water it takes to produce individual products (like coffee) as well as information regarding water consumption.
Lit by the sun and featuring amazing shades of blue, the Waving Wall remind us just how precious water really is – even though it covers 70% of our planet, only 3% is actually fresh water. The total capacity of the bottles used to build the Waving Wall is bottles 22.800 liters, which according to the designers of the art piece is the amount of water needed to produce just two pairs of jeans!
