Earth Is Running Out of Sand

"It is widely distributed in space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide (silica) or silicates. More than 90% of the Earth's crust is composed of silicate minerals, making silicon the second most abundant element in the Earth's crust (about 28% by mass), after oxygen. "

"Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar."

For some reason I don't think we're running out of sand. However like everything else how you aquire it has consequences.
