Salt of the Earth: The substances that shaped the course of humanity

The basis of human life is built upon various elements. Have we forgotten how important they are? Sky News’ economics editor, Ed Conway, explores whether we’ve lost touch with them in his new book Material World – and why they could fuel our downfall or build a better future. He joins Alex Andreou in The Bunker to discuss.

• “We have forgotten some of the physical underpinnings of our time.” – Ed Conway
• “The internet is not an ethereal thing, it is a physical product.” – Ed Conway
• “My objective was to try and remind ourselves of the stuff around us and explain how they began in the ground.” – Ed Conway
• “There was a time where it seemed like the electrical age couldn’t begin because there wasn’t enough copper.” – Ed Conway
