    This is awesome! I’ve heard liberals talk about China’s sand usage as part of their China-bad smearing without offering any solutions. Artificial sand from mine tailings (a waste product) has basically no downsides, since those tailings would be produced regardless.

    i had no clue sand was even a resource we could overuse, is it more of an exhausting local resources problem and we could pull from the like the sahara forever if we worked out the logistics/maybe need special types of sand or are we literally in danger of actually beginning to pull too much sand from literally everywhere?

      Sand for construction is a limited resource. Not every sand works to make concrete.

      Generally, it has to be river sand, because sea sand has salt and must be washed, and open air sand is pulished by wind, making it worse for building.

        ah thank you for the info! seems like something i should have learned in school, although I learned very little about protecting the environment in school tbh so it’s not that surprising

      In India there are “sand mafia” who illegally dig up sand from river beds. It is profitable because it’s used in construction so much.

      Which they’re doing, using a waste stream. I imagine the machinery is largely diesel at the momebt, but could be converted to electric in due time
