Our Material World with Ed Conway
Dylan talks with journalist and author Ed Conway about three materials that our entire civilization depends on: salt, copper, and sand. They visit the biggest man-made hole on Earth, a salt mine large enough to fit the Eiffel Tower inside it, and a single mine in North Carolina that is essential to nearly all the world’s computer chips.
