Riyadh city does not have any natural resources at all .
it is different from any other Saudi cities
it is not by the coast sides .
it is does not have a suitable climate for agriculture
it has no oil nor natural gases resources .
it does not have nice weather.
for decays ..it coasted billions and billions of $ to build and maintain this city that came from nothing in the middle of nowhere .
at Protected content because of Gulf war 2 ..people escaped back to their home areas and countries ...the population ratio and economic sharply dropped .
I always ask myself this question : what would it be for Riyadh if the oil run out ??
