Today I learned about sand.

Specifically, I just learned that while sand seems plentiful, the kind used for building is increasingly scarce, to the point that there are lucrative black markets going on in parts of Asia moving sand about. Better than killing animals for it, I suppose, but dang. Also, if I had money to invest, it looks like builder's sand is a sure bet. More than that, it seems to be fairly uncommon knowledge for now for the general public. But Vietnam, for instance, looks to run out entirely of building sand (used in concrete and the like) in the next 2-3 years. Several countries, including China, have already banned the export of sand. Can you imagine what will happen worldwide once it becomes expensive, if not impossible, to build things anymore? No road repairs, no new buildings, that sort of thing? It's a bit scary to think about, honestly. Can concrete be recycled?

Also, I just binged season two of Stranger Things. It was decent. Except for the endings, I still like season one more though. Two did have a great ending. I think the main issue I have with this new season is that certain parts/characters in it seem like they're included for no reason, save maybe for setting them up for a potential season three. Ah well. Still a fun watch.
