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
