Faillite hydrique : c'est l'expression qui remplace la “crise de l’eau”, pour souligner l'aspect durable de la situation. On fait un point sur la situation de l'eau potable dans le monde, en direct sur @franceculture.fr dans la #ScienceCQFD.

Two scientist walk through a lab. One is saying: "I am a scientist, Martin. My observations must be meticulously documented, rigorously analysed and objectively verified. Haste is the enemy of wisdom!" The other asks: "But could you share a preliminary appraisal of your general thinking?" The first replies: "Well, if you insist on a crudely reductive answer, then, yes, I had a nice christmas."
