all the while, more people flock to cities as sea levels rise
stopped there. sea levels have not changed in any meaningful way.
speaking to the rest of the video, Sand is created as rock and mineral are broken up through erosion. so much sand has been created up to this point, and the world continues to replenish it so long as the ocean has currents, there's absolutely no way we could use it all up.
Basically, there's places that will let you dump loads (tons) of concrete for free because they have huge machines that grind it all back down to aggregate again.

this video is bullshit
Lots of concrete and aggregate is recycled.

I'd wager that all the dust that falls on us also turns into more sand given enough time.. which just has me asking more questions lol
