Also, what almost everybody does not know: sand is running out. The sand needed to build concrete with. Desert sand is unusable, its grains have no compatible geometry. The immense hunger for concrete to build ever more cities, skyscrapers and sealed infrastrructure with, has led to a race at sea for "harvesting" suitable sand from the seabed. What is left behind in the process, is a dead area. And already years ago I saw documentary on it showing that they run out of sand. Construction sand is one of the most asked-for commodity on the global trade market now. ![]() We are too many.
