What’s a resilient biosystem? Healthy soil, healthy water, healthy cycles. They’re so key that even defence departments around the world are starting to invest in creating them, as research shows we have just 60 harvests left if we stick to our industrialised system of agriculture.

There’s hope for us yet, and it lies in the soil. Microbiologist and regenerative agriculture expert, Walter Jehne, joins me to explain how soil can capture carbon, promote global cooling, and feed billions on very little space. He explains how politics got in the way of progress in the 70s, and why governments are scrambling to speak to him and his team.

This is an utterly fascinating discussion (please bear with the lower quality recording). Walter was suggested by listeners so, please, if there is anyone you would like me to get on the show, don’t hesitate to reach out.
