The world is running out of sand.
It's one of the most used materials in the world for construction but islands are disappearing because of its limited supply.
Oh no. For some reason I thought we were manufacturing the sand used in construction and stuff. At what point do we stop stealing it and start making it? Is that actually any better?
Isn't one of the issues that the sand in the deserts isn't the right kind?
Yes, sand in the desert and beaches is "too old", in other words, it's too smooth and can't hold material together. That's why Dubai is importing huge amounts of sand while being literally a city in the desert.
Dubai needs to stop it.
So all we need to do to increase our supply is to rough up some sand?
Some companies came up with an alternative by grounding cement blocks into cement sand instead.
Got it. I'll just make me some concrete... Alright I need
But we can make sand so you don’t have to worry about that part
Nice one. lol
On a more serious note, they can find cement from smashed buildings. Destroying old rundown hotels to develop something else. Cool, some one wanna buy those debris and put them to some good use.
How do you make sand lol.
Put rocks through the "coarse" setting on your coffee grinder.
I just chew dried pasta.
of coarse
That made my teeth hurt.
Same way nature does, grind up bigger rocks
Why not just use the rocks themselves then
Because they're not sand, silly!
Crush big rocks into smaller rocks?
By rubbing sandpaper..duh
Shells, coral, and a whole lot of time.
Good. I hate sand.
Ani?
I heard that in the high pitched voice of Jar Jar Binks
So Water world had it right apparently
Are you saying we should put dibs on Sahara property?
