>The world makes a lot of concrete, more than 10 billion tons a year, and is poised to make much more for a population that is forecast to grow by more than 25 percent by 2050. That makes sand, which is about 40 percent of concrete by weight, one of the most-used commodities in the world, and one that is becoming harder to come by in some regions.
And the more concrete you make, the more sand you get. What's not to like? Could this be why the US government is currently trying to buy Greenland, perhaps?
