Sebastian Heitmann The Great Simplification

On this episode, venture capitalist and entrepreneur Sebastian Heitmann discusses his work in tech innovation towards more sustainable futures. Technology will inherently be a part of any human future – the question is what will this technology be? Sebastian’s work focuses on finding what is termed ‘Gigacorns’ – scalable inventions for low(er) carbon futures. If successful, this could result in large scale reductions in the CO2 emissions for global society.

Saving Bats to Save OurselvesWith Iroro TanshiThe Great SimplificationEp 241 | Iroro Tanshi

In this episode, Nate is joined by Nigerian bat biologist Iroro Tanshi to explore how the rediscovery of a bat species unseen in Nigeria for 45 years – and a wildfire that destroyed half its habitat just days later – launched a community-led fire prevention program. Iroro explains how listening to farmers, who no longer knew when it was safe to burn their fields, led to a simple fire danger warning system that local leaders then backed with their own bylaws, directly addressing tragedy-of-the-commons dynamics. She also shares what it’s like to navigate conversations about climate and biodiversity with rural Nigerian communities, and how her team is now scaling their fire management solution across the tropics.

A Shattered Market?With Rory JohnstonThe Great SimplificationEp 240 | Rory Johnston

In this episode, Nate welcomes back oil market analyst Rory Johnston for an update on how the crisis has evolved since April. Rory explains why diesel is now the epicenter of the crisis, with crack spreads running five to six times their historical norm, driven by both the Iran war and Ukraine’s strikes on Russian refineries. He also unpacks one of the unexpected moves that lessened the severity of the energy shortage: China’s unprecedented 45% cut in crude imports, which he calls the “Beijing Swing.” Tying these trends together, Rory and Nate explore how soaring shipping costs have fractured a once-global oil market into regional pockets and how the poorest nations are bearing the brunt of demand destruction.

Earth's Oldest TeachersWith Robin Wall KimmererThe Great SimplificationEp 239 | Robin Wall Kimmerer

In this episode, Nate is joined by Robin Wall Kimmerer to explore what we can learn from some of Earth’s oldest and smallest beings: plants. Robin weaves together her experience as a botanist and a Citizen Potawatomi Nation member to offer what she’s learned about living well within nature’s limits, including practices such as the Honorable Harvest and the importance of restraint and reciprocity. She also shares the Potawatomi prophecy of the Seventh Fire, in which humanity stands at a fork between a scorched path and a green one, and can only move forward by walking back to recover what was lost along the way. Robin frames this moment as the age of remembering – an invitation to restore the land and our relationship with it.
