Sand, an Essential, Finite ResourceXenius
Sand is everywhere: in concrete, glass, road surfaces, microchips, solar panels and even cosmetics. In 2019, the global demand for sand and gravel was between 40 billion and 50 billion tonnes. This has tripled in the last twenty years and specialists estimate that it will continue to grow by 5.5% per year in the manufacture of concrete alone. But it's a finite resource, and our reliance on sand isn't sustainable in the long run.
