In contrast to ‘The Great Simplification’, some might call the events of the last few hundred years a ‘Great Complexification’ in terms of relationships, governance, supply chains, and many other human activities. Today’s conversation with economics journalist Ed Conway focuses on the six essential resources that underpin our modern economies – sand, salt, iron, copper, oil, and lithium – and dives into the (often unseen) environmental and human costs of extracting them, as well as the surprisingly fragile global supply chains they fuel.
In order to understand what possibilities – and dangers – may await us in the future, we need to understand the realities and constraints of the present, as well as the fail points of the past. What does it take to mine, refine, and transform the materials that are foundational to the world around us – which many of us now take for granted? How can we ensure the stability of global supply chains, and could we predict potential disruptions and chokepoints before they arise? If we understood the intricate web of complexity, energy, and resources that go into everything we consume, would it change our expectations for how much we need in order to live a good and fulfilling life?

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
