      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.

          River sand is rougher, sea sand or desert sand is either too rough or almost polished round.

          It still works, it generally tends to crack more easily or damage steel bars due to salt.

              Yeah, that works. Then again, China is kind of demonstrating that crushing rocks into sand also works.

              So whatever pollutes less, I guess.

      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.

          There has been some crackdown but the government does not intend to solve this problem. First of all, the fascists do not give a single fuck about the environment. But more importantly, criminals like this are often in cahoots with the local government officials.
