Описание: We are surrounded by endless deserts, yet the world is running out of sand. Every year, tens of billions of tons of sand are taken from rivers and oceans to build our cities, while desert sand remains almost useless for construction. This video reveals the hidden science behind sand, why desert sand can’t be used for concrete, how countries rich in sand still import it at massive costs, the rise of sand mafias, and what happens if humanity keeps building at this pace. Sand looks ordinary, but it may become one of the most dangerous resources of the future.
