This hour, we’ll talk about how humans throughout time have turned to the Earth for the materials that power our civilization, the subject of the new NOVA series “Treasures of the Earth: Gems, Metals and Power,” which airs tonight on KERA-TV.
We’ll talk about how access to rare metals may swing the balance of global power in the digital age with the author of “The Elements of Power: Gadgets, Guns, and the Struggle for a Sustainable Future in the Rare Metal Age.”
