Rocks could save the world (Yes, rocks) | Elise Cutts

Mount Teide is one of the world’s largest active volcanoes, and there may be a way to use the basalt rock inside it to save humanity. Obviously, destroying an ancient volcano would cause catastrophic and unpredictable ecological fallout. But what if we harvested only some of that basalt— could it really stop climate change? Elise Cutts explores the fascinating science of enhanced rock weathering. [Directed by Ivana Volda, narrated by Susan Zimmerman, music by Stephen LaRosa].
