We’re taking a break for President’s Day here in the US. So here’s one of our favorite stories you might have missed. We’ll be back tomorrow with a new episode. Thanks for listening!

Here’s a random yet important fact: Copper is one of the very best conductors of electricity of all metals. And that matters, because as we move toward a world in which more and more things in our lives plug in or charge up–not just your phone, but electric vehicles, solar panels and wind turbines that will power the future–copper is in increasingly high demand. 

Some of the richest reserves of copper are found in Southern Africa. But getting it from deep underground and trucking it thousands of miles to buyers can be a harrowing journey. Without more production or new mines, the world could be looking at shortages, and soaring prices for copper and the products that use it.

Reporters James Attwood and Yvonne Yue Li join this episode to explain what a coming copper shortage could mean for us all. And reporter Matthew Hill describes his trip to a huge mine in Zambia, where he descended thousands of feet to see copper being blasted from the rock.
