Tbh there is kind of a sand shortage

Or at least we are using it up faster than it is created

    To be fair, that's referring to sand used for concrete, which needs to have a rough, jagged texture. Something that is largely achieved through water-based erosion and not wind-based erosion.

    To be fair, you can use desert sand for concrete by reducing the amount of water

    You can't completely replace construction sand with desert sand but you can replace some if you also add fly-ash however this is mostly just lab studies as real life examples are extremely scarce.

    A cool thing is that you can create a type of concrete called Starcrete (https://www.degruyterbrill.com/document/doi/10.1515/eng-2022-0390/html) that is 2-3 times stronger than regular concrete by mixing martian regolith and potato starch. If you lack potatoes you can also make a version of it as strong as regular concrete if you replace the starch with human blood.
