Water, the natural treasure.
« Water is the primary principle of everything ». Such was the conviction spread by the mathematician, astronomer, and Greek philosopher Thales of Milet (~624 to ~548 B.C.) Isn’t it water, in effect, that enables plants to grow, quenches the thirst of man, and houses the fish that nourishes him? Isn’t it also water, raining from the sky, or buried in the earth, that irrigates farmland and provides greenery to nature? Among all the things visible to man, Thales emphasized, water is the substance that takes on the most varied forms: it is present in the form of ice, snow, gas, fog, and liquid, not including rocks, which the ancient Greeks believed were made of frozen water.
Made up of a very simple molecule, two atoms of hydrogen attached to an atom of oxygen (chemical formula: H2O), water is certainly one of the most interesting and most indispensable substances for humans whose bodies are made up of, on average, 70% of this colorless and odorless liquid. Without water, no life would be possible on earth, and man would survive only 4 or 5 days without drinking.
However, the reserves of available water for living beings is not unlimited: of the 326 cubic miles of water found on our planet, only 3% is fresh water!
The protection of aquatic resources is thus a task of primary importance and for the past few decades many projects have been undertaken by the State, the communities, and industry to clean the waterways that were dirtied and contaminated in earlier times because of thoughtless exploitation.
The EUROPA 2001 stamps show a stream of clear and fresh water, similar to what is found in the tourist region of the Mullerthal (Luxembourg Little Switzerland), as well as a pond which is home to numerous species and is dominated by the "Kaltreis" water tower in Luxembourg-Bonnevoie, which provides potable water to a large number of households in Luxembourg City.
