4. Water, a virtuous cycle
An essential condition for the presence of life on earth, water is a resource that has always been tamed throughout the world to serve cultures. Agriculture is the most water consuming activity, representing more than 70% of world consumption. From its abundant presence, cyclical or scarce according to the geographical zones, were born singular and ingenious irrigation practices. Its powers and the biodiversity it harbors have aroused the curiosity of researchers on various themes ranging from the memory of water to its dynamization.
Should man intervene at all costs to control its flow and thus better store it? Here again, the functioning of living organisms leads us to consider water as a cycle that must be preserved and promoted.
A three-day-old human embryo is 97% water.
During Summer, a mature oak tree can transpire up to 500 liters of water per day.
Fruits and vegetables are essentially made of water: 78% in wheat, 85% in a carrot, 95% in a melon.
