On one hand, you are not wrong, sands differ in qualities, but the question is what you need to make from it. Glass-grade sands aren't everywhere, but they are abundant anyway. Some industries, like solar panels production, require higher purity, and such sands reserves are way more limited.
What I left unsaid to be polite was if they missed/hand waved something that even I know, what else is missing from this analysis? It feels like a gross oversimplification of a very real, very multifaceted problem.
I don't think it's fair, while "one of the most abundant" isn't well-nuanced wording, but the argument is that glassmaking won't exhaust glass-grade sands in historically near times, and it's true.
