TGS90 Nick Haddad The Great Simplification

Show Summary

On this episode, Nate is joined by Professor Nick Haddad, a conservation scientist with a focus on butterflies and other insects. Nick unpacks what decades of research have indicated about the declining state of insect populations, which act as the foundation of critical ecosystem functions. The overlooked degradation of butterflies, beetles, bees, ants, ladybugs, and countless other species have huge ripple effects across our local and global ecological functions – from a loss of bird populations to a reduced ability to grow food. Why are we not more concerned about the health and vitality of these critical organisms? Can humans – or life as we know it – survive without these little creatures? What can we do as individuals, businesses, and governments to help insects rebound as quickly as possible, and in turn strengthen the health of everything else.

About Nick Haddad

Professor Nick Haddad is co-lead of the Long Term Ecological Research site at Kellogg Biological Station at Michigan State University. He leads decades-long, landscape-scale experiments that bring scientific principles to conservation actions. He studies how landscape diversity, including prairie strips through croplands, affect biodiversity, especially of plants and insects, and of ecosystem services including pollination, biocontrol, and decomposition. For three decades he has led the world’s largest experiment testing the role of landscape corridors in increasing dispersal of most plant and animal species, and increasing plant diversity. He has conducted long-term restoration experiments to guide conservation of rare butterflies in the face of climate and land use change. Nick brings together ideas in science and management through ConservationCorridor.org.

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

Earth Day 2025With Nate HagensThe Great SimplificationEp 187 | Nate Hagens

In this Earth Day presentation, recorded earlier this year, Nate offers nine broad paths for individuals to cultivate resilience in an increasingly uncertain and unstable period of human history. From the intellectual & ecological to the spiritual & psychological, these ideas might be considered waypoints for navigating the human predicament, and -in aggregate - help build 'scout teams' of humans working on the upcoming cultural transition away from infinite material expansion.

The Packaging RevolutionWith Wes CarterThe Great SimplificationEp 186 | Wes Carter

Packaging is an unavoidable feature of modern life. It’s so embedded in our products and systems that even the most environmentally-minded consumers struggle to avoid it entirely. Yet packaging accounts for nearly half of all plastic waste, contributing to widespread ecological harm and growing threats to human health – highlighting the urgent need for an overhaul of packaging materials and industry practices. So how are some industry leaders reimagining materials, systems, and supply chains in ways that align with the realities of our finite planet?

The Myths Shaping Our EconomiesWith Josh FarleyThe Great SimplificationEp 185 | Josh Farley

Economic theory has come to wield outsized influence over our societal goals, decisions, and policies – often relying on models that claim to optimize how human systems function. Yet the outcomes of our modern economic structures tell a different story: accelerating ecological collapse, widening inequality, declining public health, and increasing social disconnection. What if the foundational principles of mainstream economics are actually built on false assumptions that obscure the realities of our world?
