I understood its main benefits being that it was both fairly cheap to construct and inherently well insulated. As far as sustainability goes I can't see it making a good coffee stand and I think there's some sort of looming concrete grade sand shortage (?) due to our misuse/addiction to paving things.
Oh it's not you, there are lots of articles written about it that don't mention it's not an actual problem unless you're a sand mining company that wants to continue to rip up river ecosystems

Not really, there's a looming shortage of cheap riverbed sand near construction projects but you can just crush glass and get a suitable substitute
Thanks, I didn't know the details & it seemed bizarre; just a half remembered article fragment I guess.
