I support your effort to spread the message about the sand shortage
But I do have to tell you that the construction industry consumes 50 billion metric tons of sand a year and the semiconductor industry makes $650 billion... so every computer chip would have to cost 10 cents and be made completely of silicon and weigh 7 kg each in order to have parity with sand consumption for concrete. I think the price of sand is just gonna go up and they're still gonna keep making new ones. 😢
