hello it is a viable study except that it misses realism to go in 2050. the problems will not come from the consumption of drinking water in the world but of the rejection of this consumption (waste waters) if that Ci contains micro pollutant chemical. one will be then in the position of obligation to treat the water of the water tables to make it drinkable. It is a diagram loan of much more realism
