Sand has transformed modern civilization. It is the ubiquitous commodity; in our infrastructure, in our industry and even in our personal care products. Yet due to its characteristics, the supply chain is fragmented, disastrous for our environment and often corrupt. And by a tragic quirk of geometry, desert sand is unusable, meaning we wreck our riverbeds and oceans to acquire it. In this episode, author and journalist Vince Beiser joins us to discuss sand and its role in the modern world. Vince is the author of The World in a Grain - the story of sand and how it transformed civilization.
