La menace climatique dans la region MENA
En 1960, un champ d’un hectare pouvait nourrir 2 personnesIl y avait 3 milliards d’habitants sur Terre soit 0,43 hectare par habitant
En 2000, ce même champ nourrissait 4 personnesIl y avait 6 milliards d’habitants sur Terre soit 0,25 hectare par habitant
En 2050, ce même champ devra nourrir 6 personnes
Nous serons 9 milliards d’habitants sur Terre soit 0,16 hectare par habitant
Sommes nous a l´aube d´une crise ?
