Modern North America is a world built of minerals. Buildings, transportation networks, communication systems, waterworks, machinery, and appliances of every kind—all of these depend on minerals clawed from beneath the earth’s surface. A modern American automobile now contains at least thirty-nine different minerals, everything from aluminum and bauxite to tungsten and zinc. Computers and smartphones can contain even more, including precious metals such as gold, silver, and platinum, as well as rare earth elements such as europium and yttrium that provide color for their liquid-crystal displays.¹ Electrical lines depend on copper or aluminum; pipes are formed from several different... | Modern North America is a world built of minerals.
