Stop and Smell the Guano: How Fertilizers Saved the World - Episode 837 - a podcast by American Chemical Society

November 08, 2017 - A little more than a hundred years ago, the world's fast-growing population was outstripping humanity's ability to feed itself. Mass starvation was only averted when a pair of brilliant German scientists developed a new chemical process to snatch nitrogen gas from the air and use it to make modern fertilizers. As science writer Thomas Hager explains in this episode of Science Elements, it's a story of wars, greed, bird droppings and a discovery that continues to dramatically shape our lives today.
