Software Man : It's amazing how people in the desert never starve because of all the sand which is there

The Great Arabian Knight : Earth is running out of earth

Vasectomy Fail : I don't like sand. It's coarse and rough and irritating and it gets everywhere.

Jeffrey Koelewijn : Instead of concrete you can use hempcrete, mycelium, ferrock or ashcrete and more will be found out. And maybe if desert sand can't be used to make building materials, maybe it can be used or is even ideal for something else.

jarupongch : How to become a billionaire: Step 1: Make desert sand usable for concrete Step 2: ??? Step 3: Profit $$$

Science with Smartinator Plus : Woaaaaah Amy is back

Flynn Parish : The market mechanism will solve the supply issue, given there is no oligopoly of the industry. If the supplies of useful sands were to fall, the coming market price will reflect it; eventually would give rise to new innovation of building methods and new discovery of material.

CORNER SOUNDS : What if someday we're running out of people!!😱

brendan wilson : Lol, make sand

SoundKiller Official : Why don’t we take the sand in the dessert and push it to the water so we can use it?

Feynstein 100 : In case anyone's wondering, desert sand can't be used for concrete because the particles are very spherical. This means that instead of interlocking with each other, they slide past one another. Hence the sand's structural properties are very poor. As for why the particles are so rounded, that's because the desert has existed for so long that any irregularities in the particles' shape has been eroded away by constant motion because of the wind (analogous to how pebbles at the bottom of a river are generally rounded). Source: am a civil engineer EDIT: It's not that desert sand *can't* be used for making concrete. It can. However, we prefer not to because the concrete would be much weaker than that which uses coarse sand.

Some Thing : When are you guys going to look a little further on this? This isn't a NEW global crisis, it's the cause of a way longer crisis. It's just a matter of connecting the dots. "Global warming" (read: climate change) isn't the cause of the "raising" sea levels, it's the mining of sand which causes the beach to retreat to even the levels out. This is indeed exactly what's making the islands disappear. Watch the documentary called 'Sand Wars' and you'll get what I mean. The dots? You'll have to connect themselves (for once).
