A race is on to exploit the last bonanzas of gold, silver, and industrial metals left on Earth. These metals are not only essential for all material comfort and need, but for the transition to clean energy: in the coming decades, billions of tons of copper, nickel, silver, and other metals will be required to build electric vehicles, solar and wind installations, and green infrastructure. We need more metals than ever before, yet the qualities and quantities are diminishing, making the extraction process more polluting to land, air and water. And most of these metals will be mined from the global south, where social conflict will only grow, led by Indigenous peoples demanding a greater say in how their wealth is used.
