More on this later. At least we still have enough helium.
From the Daily Mail:
The world is running out of sand: Shortage could mean there won't be enough to make glass vials for COVID vaccinesA couple more articles to read:
"In recent years, the demand for sand has grown so dramatically, that suppliers have been looking elsewhere – namely, to beaches and the seafloor. The use of marine sand adds another step in the concrete-making process. Its salt must be removed, to avoid any risk of metal corrosion in the final structure. That comes with a cost, but the sand market is so crazy that apparently, it’s still worth it. Speaking to INSIDER in 2018, Beiser claimed that, because of its critical role in construction, “the price of sand has about quintupled in the past 30-40 years.” The makers of documentary film Sand Wars claim that sand is now a US$70 billion industry."
A hidden shortage: why the world is running low on sand
So I guess it's not an exaggeration to say that time is running out on sand. Seriously.
