TGS79 David Montgomery and Anne Bikle The Great Simplification

Show Summary

On this episode, Nate is joined by “free range biologist” Anne Biklé and “broad-minded geologist” David Montgomery – a married duo who have been educating about the link between soil and human health for nearly a decade. As we continue to strip the land and soil of its life supporting capacity, our food has become less nutritious, even as we’ve received more calories. Has the age of ‘The Green Revolution’ – accredited with preventing millions from famine – led us to a new epidemic of starvation in the form of micronutrients? How do our modern systems degrade the land, leaving us with lifeless dirt even more dependent on fossil inputs? Can we implement better agricultural practices that lead to lively and fertile soils, better health, and a reconnection with the land that feeds us?

About Anne Biklé & David R. Montgomery

Anne Biklé is a science writer and public speaker drawing on her background in biology and environmental planning to explore humanity’s tangled relationship with nature through the lens of agriculture, soil, and food. She is particularly enthralled with the botanical world and its influence on humanity throughout history. Her writing has appeared in digital and print magazines, newspapers, and her work has been featured in radio and independent documentary films.

David R. Montgomery is a MacArthur Fellow and professor of geomorphology at the University of Washington. He is an internationally recognized geologist who studies the effects of geological processes on ecological systems and human societies. He is the author of several textbooks in his field and his work has been featured in documentary films, network and cable news, TV, and radio.

Anne and David are married and live in Seattle, WA. In 2023, they published What Your Food Ate: How to Heal Our Land and Reclaim Our Health, which builds on their trilogy of books about soil health, microbiomes, and farming—Dirt: The Erosion of Civilizations, The Hidden Half of Nature, and Growing a Revolution.

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President

That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher

We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF

This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor

Is the U.S. Electric Grid Stable?With Meredith AngwinThe Great SimplificationEp 196 | Meredith Angwin

For many people in the modern world, electricity powers everything we do. Yet we take for granted how power flows in the background, seemingly always accessible to us just by flipping a switch. In fact, most of us are completely unaware of what it takes to generate and transmit the power we so deeply rely on, let alone the policy decisions shaping our electrical grids – or how they might affect reliable access to power. How do today’s electrical grids actually work, and do they align with our long-term goals for human and planetary well-being?

Moral AmbitionWith Rutger BregmanThe Great SimplificationEp 195 | Rutger Bregman

The overarching definition of success today often looks like the accumulation of stuff – money, cars, property, clothing – anything that signals wealth. This means that success is also synonymous with overshoot, extraction, and consumption – none of which lead to healthy outcomes for the planet or the global good. But what might be possible if we were to redefine success to prioritize collective well-being instead of personal gain?

The Past and Future of Societal CollapseWith Luke KempThe Great SimplificationEp 194 | Luke Kemp

For many people today, the idea of societal collapse is unimaginable. Yet history shows that well-established civilizations have fallen again and again – often for similar reasons. In fact, the same forces that build empires can also culminate in their downfall. How can understanding these historical patterns help us prepare for similar existential risks we may already be facing today?
