This isn’t any more true than it was 15 years ago when I first saw it on imgur. Those are close ups of small shells found in some tropical sand that have been separated from regular sand. Sand isn’t fucking magic its small rocks.
And yet if you look at https://magnifiedsand.com/ it is insanely cool and not too different from the images in this post. I don’t think that entire website is fraudulent. Glad I didn’t see your comment first because it would’ve turned me off of even looking into this further. When I did look into it further, I was thrilled.
White sand is calcium carbonate that has been eroded down to sand size particles. One way that happens is by parrot fish grinding it up, but weathering surely created the vast majority of it.
“On the Great Barrier Reef, for example, researchers estimate that parrotfish are responsible for producing over 85% of the new sand generated annually.”
How does that compare to the quantity of sand already in existence? There was a long period of time (millions and millions of years) when there were no parrotfish, but billions of tons of calcium carbonate being eroded by the weather.

Also white sand is fish poop.

Or Big Magnifier would have you believe.

Could very well have been other animals over time.
Seeing as there’s now a shortage of water-eroded sand, probably a good portion of it
Are you thinking of sand that’s easily accessible (so not under many metres of sea) and suitable for use in concrete?
What a stupid thing to bicker about. Good work, people on the internet. o_O
I didn’t read it as bickering at all, just two people with an interest in sand, trying to get to the truth.
I might be extra cranky. I hate sand.
Fuck off, Anakin.
We’ve all got our hobbies
And how much of it is at least 50% microplastics now.
Hajabawhat now? How is white sand fish poop? Isn’t it just sand? Or do you mean like the white particles in mixed sand are fish poop?
White sand is fish poop. https://www.animalsaroundtheglobe.com/this-fish-eats-coral-and-poops-out-perfect-white-sand-5-354250/
“This fish produces white sand” is pretty far away from “all white sand is produced by fish”.
Shhhhh, let them believe. It is okay
