In addition to creating jobs and new technologies, mining provides us with essential ingredients for everyday items such as cookware and electronic components; we also rely upon mining for the raw materials we need to build cities, ships, automobiles, and other artifacts of technology. All of these industries create more jobs, spurring economic growth.
