Back in 2017, I posted about the potential for a sand shortage in the future. In that post, I pointed to an article that discussed some of the uses of sand, which are probably way more than you realize.
Fast forward to today, and this article about the possibility of a sand shortage came out in Science, which is the official publication of the American Association for the Advancement of Science (AAAS). The article cites a United Nations (UN) report that highlights the political aspects of sand, specifically that sand is a resource and thus a commodity. As such, there are sustainability issues.
The article is a very interesting read, especially when it claims that sand is second only to water in human usage (by volume).
