And even the silicon chips inside our phones and computers – along with virtually every other piece of electronic equipment in your home – are made from sand.Īnd where is the problem with that, you might ask? Our planet is covered in it. The glass in every window, windshield, and smart phone screen is made of melted-down sand. The concrete used to construct shopping malls, offices, and apartment blocks, along with the asphalt we use to build roads connecting them, are largely just sand and gravel glued together. It is the primary raw material that modern cities are made from. Trivial though it may seem, sand is a critical ingredient of our lives. They are some of the latest casualties in a growing wave of violence sparked by the struggle for one of the 21st Century’s most important, but least appreciated, commodities: ordinary sand. Though separated by thousands of miles, these killings share an unlikely cause. A Mexican environmental activist murdered in June. Two Indian villagers killed in a gun battle in August. A South African entrepreneur shot dead in September.
