Jason Bradford The Great Simplification

On this episode we meet with author, activist, farmer, and teacher, Jason Bradford, who discusses the energy intensity of our modern industrial agriculture system. 

How do we feed billions of people with depleting energy systems? How do we also protect existing biodiversity and ecosystem health? We also discuss what makes for healthy soil, why we’re losing it, and how small farms can help get it back – while creating higher yields of healthier foods for fewer inputs.

About Jason Bradford

Jason Bradford has been affiliated with Post Carbon Institute since 2004, first as a Fellow and then as Board President. He grew up in the Bay Area of California and graduated from U.C. Davis with a B.S. in biology before earning his doctorate from Washington University in St. Louis, where he also taught ecology for a few years. After graduate school he worked for the Center for Conservation and Sustainable Development at the Missouri Botanical Garden, was a Visiting Scholar at U.C. Davis, and during that period co-founded the Andes Biodiversity and Ecosystem Research Group (ABERG). He decided to shift from academia to learn more about and practice sustainable agriculture, and in the process, completed six months of training with Ecology Action (aka GrowBiointensive) in Willits, California, and then founded Brookside School Farm.

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

Rod SchoonoverThe National Security Risks We’re Not Prepared ForWith Rod SchoonoverThe Great SimplificationEp 183 | Rod Schoonover

National security concerns have been the invisible hand guiding governance throughout recorded history. In the 20th century, it was defined by a country versus country dynamic: whichever nation was the strongest and most strategic was also the safest. But today, our biggest national security threats don’t come from opposing nations – they are “actorless threats” that emerge from the breakdown of the complex systems we all depend on – from the stability of our planetary systems to our intricately complex and fragile global supply chains. In this unprecedented landscape, what is required of us in order to keep our citizens safe?

Movie Re-ReleaseThe Systems Science Behind Our Global CrisesWith Nate HagensThe Great SimplificationEp 182 | Nate Hagens

Three years ago, my team and I created a 30-minute movie that provides a comprehensive systems analysis of the human predicament—spanning energy, economics, ecology, and behavioral psychology. This beautifully animated film aims to help viewers understand the interconnected crises defining our era.

Globalization End GameHelena Norberg-Hodge HeadshotGlobalization End GameWith Helena Norberg-HodgeThe Great SimplificationEp 181 | Helena Norberg-Hodge

Over the last few decades, humanity has globalized everything – from food production and supply chains to communication and information systems – making countries, businesses, and individuals more connected and reliant on each other than ever before. Yet, with this increased interconnectedness comes more complexity and fragility. What have we lost through the globalization process, and how might we fortify our communities by investing in local economies?
