Climate change is just the get away crisis.
Sand, and other raw material bottle necks are "only" jeopardizing modern economical/technical development (on which our entire world economies are based).
Meanwhile, the year isn't over yet and we've already crossed 2 more planetary boundaries. Each one having the potential to render human life on earth fairly unpleasant.

Sand? We've reached the grotesque when Saudi Arabia has to import its sand from the other side of the planet.
And yet, this pale in consequences compared to, say, the Nitrogen and phosphorus cycles which threaten nothing less than our ability to feed ourselves.
