Are We Running Out Of Sand?

What a mind-blowing article in Hightower's Lowdown! Our Ravenous Appetite Turns Humble Sand Into An Endangered National Treasure

Who'd have thought, in Saudi Arabia, with all that sand, and so much of it is unusable in making concrete, and to build all those new buildings in Dubai they had to import sand from Virginia. The sand in the desert is too fine for making concrete.

Sand is also used for fracking, consuming tons of it!

There's a CEMEX plant around Monterey Bay that is due to shut down in 2020, actually a sand plant, they've been extracating sand there for decades. Time to shut it down!

Being a concrete lover, it never occurred to me that not just any kind of sand will do to create it.

We've had threads here before on issues associated with sand shortages.

Anyway, I love posting this comic when the topic comes up.

Interesting article I read a couple days ago in the times:

It's a shame that the sediment from the constantly filling flood control debris basins and reservoirs isn't used.
