Population growth will challenge agriculture
To reduce their GHG emissions linked to food, people will have to modify their habits:
-Consume less meat or eat meat vegetal substitutes, as meat calories emits much more GHG than vegetables calories.
-Reduce their organic waste, which generates methane.
Especially, higher life expectancy and high fertility rate (i.e., still high in Africa) will increase pressure on mother nature if current habits persist.
