L’Afrique est un continent qui couvre 6 % de la surface de la Terre et 20 % de la surface des terres émergées. Sa superficie est de 30 415 873 km2 avec les îles, ce qui en fait la troisième mondiale si l’on compte l’Amérique comme un seul continent. Sa population de 1,3 milliard d’habitants classe l’Afrique deuxième continent du monde après l’Asie et représente en 2020 17,2 % de la population mondiale. Source : wikipedia
