A Global SAND Crisis?

BELIEVE IT OR NOT, there’s a global sand crisis.  This article from Futurism is interesting.

“Sand and gravel are now the most-extracted materials in the world, exceeding fossil fuels and biomass (measured by weight). Sand is a key ingredient for concrete, roads, glass and electronics. Massive amounts of sand are mined for land reclamation projectsshale gas extraction and beach renourishment programs. Recent floods in Houston, India, Nepal and Bangladesh will add to growing global demand for sand.”

The environmental impact on all this sand mining, and a shortage of sand, is huge.
