Mike Joy is a freshwater ecologist and Senior Researcher at IGPS Victoria University of Wellington. He has been working for two decades at the interface of science and policy in New Zealand with a goal of strengthening connections between science, policy and real outcomes to address the multiple environmental issues facing New Zealand.

He explains the multiple links between New Zealand’s dairy industry and environmental damage—giving a fantastic example of what a systems problem looks like in a real-world context—before diving into an analysis of the correlation between human and planetary health.
