Hunter Lovins on the circular economy of soil

In public discussion, the circular economy is often described as a way to allow technical products and their components to be used as endlessly as possible. But we can't forget about the biological cycle - how does it work when we come to the system that sustains life: agriculture? In this episode, Hunter Lovins argues that we need a 'circular economy of the soil' to feed a growing population, restore soil quality and ultimately reconcile farming systems with natural cycles. L.
