Mena climate change impact

1. La menace climatique dans la region MENA

2. En 1960, un champ d’un hectare
pouvait nourrir 2 personnes
Il y avait 3 milliards d’habitants sur Terre soit
0,43 hectare par habitant
En 2000, ce même champ
nourrissait 4 personnes
Il 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 ?
