In 2010, nations mined about 11 billion tons of sand just for construction. 50% is used to make concrete, for road construction, for mixing with asphalt, as construction fill, and in the production of construction materials like concrete blocks, bricks, and pipes. It is also used to make roofing shingles, on icy roads in the winter, railroad ballast and water filtration. Then there's glass, and more...

Apparently sand deserts do not count. And also mentioned was that no rivers now reach the ocean with their deposits...to many dams in between. So, ocean sand is preferred. OCean sand is being depleted on coastlines and not replenished. Etc. I hope some here watch. I was shocked and amazed.
