So sand is one of those resources you don’t really expect to be “non-renewable”1 and hotly contested and yet, oddly enough, it is. Specifically, the type of sand used in land reclamation activities, like that practiced by Singapore. Which poaches sand from poorer, neighboring nations in order to expand its landmass. Meanwhile, our own local sand? Mostly sold off to the UAE.
I seem to recall once watching a random late night documentary on this same subject. I’m pretty sure it was Sand Wars, mostly by a process of, “How many documentaries on the illegal sand trade can there possibly be?”
- In the sense of “non-renewable in human time-spans compared to how fast we use it”. ^
