- Sand is used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on sand means that we’re also reaching a limit on this seemingly infinite resource-and it's also in demand by... criminals?

As a geologist who works with a sedimentary basin that is mostly made of sand, you also have a big problem: the disregard a lot of miners have for fossils. Thanks to the high demand for sand, a lot of illegal mines or even legal mines but with very little inspection from governments, a lot of historical data is being crushed away by heavy machinery. It's really sad to see and it's very common.
If any parties were willing to pay a high enough price for these fossils, the situation would change fast.

@@ashoka9306 Oh, it absolutely is. At the moment it is highly profitable to acquire and sell sand. If that sand comes from out of a protected area, the government has to criminalize and stop it. If the government does NOT stop it, then said protected area will be raided until there is no sand left in it.
Similar concepts: If the government in a certain South American country does not stop farmers and corporations from burning down the rainforest, then farmers and corporations will keep burning down the rain forest.

As a kid who had horrible anxiety issues, this was a huge, irrational fear of mine, after finding out that we use sand to make glass. Thanks for bringing back the fear by making me realize it wasn't irrational 😅
You were a super insightful kid... You really were. The rest of us were just rolling in it...
I was concerned after finding out that (around 2010 was when the book was printed) that geologists predicted that sand is only a temporary commodity, that the environment itself will consume eventually (mostly the oceans, beachsand and whatnot). I now understand that there are natural processes to make the stuff, but again, a planet with 7 Billion apex predators (the most resource intensive per individual part of any ecological chain, simply because resource density gets lower the further up the chain you go), we're using it as fast as we can.
I mean, sand for glass can be gathered from deserts
I feel like fear is a powerful motivation for innovation and problem-solving. It's greatly noticeable during times of crisis or wars.

The "facts" are that 50 billion tons of anything means nothing to the planet. The amount of SO2 available to us on this planet is so mind bogglingly large, 50 billion tons are to that number what a grain of sand is to a desert. All those large numbers are mostly in this video to obscure that.

@@ekothesilent9456
"Sand" in this context is a raw material sourced from nature. "Rock Dust" is a manufactured product specifically from well tuned cone crushers at a rock quarry. The resulting product is nothing like natural beach or river sand, but is a whole different type of material with its own properties.
@@UpcycleElectronics no sand is rock particulate which is between a certain diameter in millimeters.

I think it's pretty clear we won't start fixing anything until we start dying en masse.
Covid has already cost us far more than the most comprehensive climate change mitigation measures imaginable, so we could've fixed climate change a long ago, but didn't want to and still don't.
It should be straightforward: It is a finite resource, we have more demand than (easy) supply. The price will go up, let the market work its magic. When things get expensive, people become creative, improve the processes, recycle more, explore other materials.
In real life, though, seemingly endless commodities are often priced without taking the finite nature into account. Producers only have to pay production costs, they don't really compete for the resource by paying more for the concession.
Just don't walk into the ocean
Grinding big boulder to sand? How hard is that?
@@eljanrimsa5843 "The market's magic" does depend on people behaving rationally. The more common reaction to a resource becoming more scarce (or even perceived to be - see toilet paper recently) is to grab what one can and leave it to others to figure out alternatives.
So, round desert sand could be used for the various types of glass, as it doesn't matter what the edges are like as it is melted down anyway, and what about Crushed Glass?
Crushed glass is great for a lot of uses! Mixing it into asphalt makes a road that lasts well but it is a little more slippery, so litigious US will never use it on a wide scale.
So -- use the cheapest method for melting the smooth sand, crush the glass resulting from it and then use it - problem solved.
It was decades ago that I spoke to the operator of a gravel pit. Even then he said, river sand dug out of the ground does not really meet quality requirements for concrete mixing, being too round. So the sand they sold, came out of a crusher, produced from river gravel.

@@RandallJamesPeterson correct, manufactured sand from open pit mines is cheaper in most instances to get ahold of but like the video says, not as pretty and more risky than river dredged sand. There’s quite a lot that goes into river dredging and there’s certain times of the year you can dredge because of fish mating. You have to make sure none of your river equipment is leaking oil into the water. (which is a very hard task) tons of epa, osha, and miner safety inspections.
Concrete manufacturing has specific ratios of different materials they use to make their special blend of concrete. Our river sand is a key role in their concrete manufacturing process.

where do humans came from? they keep getting larger and larger.
@@xponen our oldest human looking ancestors existed somewhere in the centre of Africa. The reason why the population of humans is so high is the lack of natural predators nowadays and due to us being on the very top of the ecosystem, not only dominating every other animal thanks to our intelligence and weapons, but also extending our own life thanks to medicine. It would require global events to deminish the human population, such as what is happening now, because there's nothing else that can. And with the thing that keeps the population numbers in check being so rare the number will just keep increasing.
@@kingofflames738 I meant "human is a growing resource" as opposed to "dwindling resources"... referring to your first comment. 80% of a tree's biomass is created from the Air, conversion of CO2 into mass.
For the last twenty plus years I’ve worked in the Albertan oil industry, primarily in bitumen extraction. At the end of the extraction process we are left with, quite literally, mountains of sand. It was initially supposed to be placed back where we got it from, with the soil and vegetation restored to what the environment resembled before the mining operation began. However, just within the last year, a new process to extract titanium from the process has also been implemented. That still leaves us, again quite literally, with mountains of sand. BTW, I have on several occasions mentioned (verbally) to management the industrial value of sand, but to my knowledge, it hasn’t even been mentioned to a director, much less a VP or anyone higher.

But it needs to be water formed 1111111
@@wertyuser798 mars used to have water, it was just billions of years ago. Mining ancient martian rivers could theoretically work!
but we have moon sand right??
@@Remonlore Technically it's called regolith, and in theory lunar and Martian Regolith could be the best for building material because due to the LACK of wind or water erosion, it's as sharp and jagged as it gets. So much so that it doesn't flow like Earth sand does, it clumps together like a sand castle despite being dryer that dry. That's thy the boot prints of the Apollo astronauts are so well defined. In fact, when mixed with a resin-like bonding agent, cement made from a proxy of regolith in a lab can be 3D printed into giant beehive-shaped domes that could serve as future habitats for astronauts on The Moon and Mars, because they're 100% airtight (protected from the near-vacuum), nearly indestructible (the team who made the first prototype tried to dismantle it with a bulldozer...the bulldozer broke first), and it's even extremely resistant to radiation, which is a severe hazard on The Moon and Mars.
Though it will probably be a long time before we start making buildings here on Earth out of lunar regolith since...well shipping ANYTHING from Earth to space and vice-versa is still RIDICULOUSLY expensive. But considering the Moon has many OTHER precious materials companies like Space X are hoping to mine, like titanium, gold, platinum and rare-Earth metals often used in electronics like iridium, maybe regolith will be on that list in the coming decades.
It would be too expensive to get it from Mars and take too long. If we mined near earth asteroids that could be done quicker although that would take a lot of asteroids. Still we have to consider the weight of the earth going around the sun. How much weight from asteroids could it slow down our orbit around sun. That’s one reason I don’t believe in evolution.

The world: "Due to overpopulation, we will run out of food, living space & nonrenewable fuel sources by the year -xxxx-!"
Me, an intellectual:
On a long enough time line, YES, there is a finite amount of everything on this planet. Simply because you will not experience this situation in your lifetime doesn't make it less real m8
Research Easter Island Extinction, and then upscale it to a planetary level.
It's not because of overpopulation. It's because China already had a massive population and they are just now actually catching up to the rest of the first world, which means they are ruining everything like the old first world did.
Good luck getting white people and former colonies to admit that.

4:30 how about crushing olivine to make new green sand that literally absorbs co2 as it gets weathered?
10:40 use a few giant (fresnel?) lenses to melt the sand together into solid rock, crush it back down to appropriately jagged sand particles?

Lot of work/energy makes it prohibitively expensive.
@@chucksolutions4579 just using the sun to melt it down requires very little energy input tho, and it can be done right where you have the biggest abundance of wind eroded sand, but I guess the biggest cost is still transportation
I went to college right down the road from the Hallet Materials Sorters Road Pit, which is an active sand mine. But they don’t do traditional pit mining there. Instead, the pit is flooded with water from the San Jacinto River and the pit is dredged for the sand below.

You guys atthe SciShow certainly cover a lot of interesting topics, that mostly go under the radar of the public in general ! Thank you ! I didn´t realize this sand problem until today...
I work at a sand and gravel plant. I spend every day loading trucks with aggregates, most popularly river sand that's been dredged from the bottom of the Mississippi. Watching this was both interesting, and oddly familiar.

Is water weathered sand really necessary for making glass?
In deserts, gypsum is a pretty common constituent of sand (it's more prevalent in arid environments) so that would be a barrier to accessing silica there. Plus populations tend to be greater around rivers than deserts.
That's a good ass question.
Doubtful, since you melt it down first. They probably already buy other sand for this industry anyway, due to pricing and availability.
It's mostly needed for concrete. Sand+gypsum+gravel+clay is the actual recipe for concrete, and since gypsum and clay are a lot more common than silica, that leaves sand as the singular main component of cement that's missing. And the finer the sand the better the cement. Because the sand is what binds the water, to the gravel in concrete.
Useful sand isn't all about particle shape, it's also size distribution; manufactured sands (from crushed rock or recycled material) often have too many particles that are too small (silt) for good concrete.
Fly ash is great for applications such as lightweight masonry blocks and prefab wall units, and as a bonus is slightly cementicious (like cement) meaning you can use less cement (which reduces overall co2 footprint).
The property my house is built is on a coastal plane made of sand, hence the reason why my posting handle is Sand Box John.
What about recycling glass into sand? It takes a lot of work to recycle glass. We actually have a problem with recycling glass in the lampworking industry. If your a smaller operation then it takes more time and resource to recycle. We just throw the glass away because its more profitable to start with new glass.
@@MrSea123456 Yea glass dust can lead to silicosis. You have to take extra precautions. Some people do smash it down in a bucket to make frit, the frit is then used for decorative applications.
Sand made from glass is a good alternative to river sand for many construction uses.
The problem is that it takes more energy per kg of sand to manufacture it than it does to mine it. Recycling glass as you know is also problematic because modern glass isn't just melted quartz. The chemistry is more complex than that and testing the composition of glass to be recycled is impractical. Manufacturing is always harder than it seems.
Simple break it and put it on a beach where poeple don't go.the water will turn it into sand and beach glass.
Transporting it is expensive. The world is run by money, so when it gets cheaper to recycle than to mine, that's when we will switch sadly

Great video Sci show. I would like to add that hydro electric dams also greatly decrease natural sand and sediment flow to beaches and deltas

Argh, why are deserts so useless? Maybe someone can figure out a cost effective process that can make use of that desert sand in concrete. I mean, there is so much of that stuff!
There's volcanic ash.
That’s due to the ecological damage it would cause
Use desert sun collected and concentrated to fuse desert sand into larger more jaggedy sand grains ?
if we want a jagged edge dirt we can make jagged edge, it just cost money.
When Germany updated the Hamburg to Berlin motorway they repurposed the substance being removed. The processing was local and quite impressive to see. That was in the early nineties nearly 30 years ago!

So… We have techniques for melting metal powders to each other, which is used for a form of 3D printing. Which got me thinking… Why not apply this in a way, to that desert sand, since it has the wrong texture?
If you use a large scale industrial solar furnace to melt the sand, it should even reduce the carbon footprint it would have if using other energy sources. And if you melt it just right, I think you could get the sand grains stick to each other without fully liquifying, so if you let it cool and send it through a crusher, it may have a rough enough texture for concrete without requiring quite as much processing as fully melted sand solids would. Or at least, that's what I imagine would be the case.
It's like: if you leave a bunch of ice cubes in your freezer for a long time, they'll fuse together like I'm picturing the sand doing. And when you try to break the fused ice cubes apart, they have a rougher surface than they used to, but it required less work than breaking new ice cube sized bits from a fully solid block of ice without gaps.

After seeing how much limestone was collected in our water heating unit when it broke because of it last month, has anyone looked into extracting limestone from city tap water? It is bad for our appliances and drinking, and you'd get a lot of free sand as a byproduct.
Calcium buildup in your water heater is not limestone. There shouldn't be any carbon in your water.
@@Ornithopter470 limescale is calcium carbonate - exactly the same component in limestone. The big problem is extracting it
limestone is mostly used to make cement, which is the binding agent of concrete. Limestone is found in the water because water can relatively easily corrode it, in particular now that rainwater and the air in cities have become more acid. You can easily see that by looking at monuments, which are mostly made of limestone.
@@bansa5616 So, if I'm understanding this, the rain dissolves the calcuim carbonate in the sidewalk, which somebody paid for, and somebody will have to pay to replace, then that same calcium carbonate comes out of solution inside pipes and water heaters, causing THEM to have to be replaced. Profit motive everywhere, even in destruction.....
