All of our industries are going to have to shrink. But how do we shrink the good ones?

Martin Hensher is a health economist and  a Professor of Health Systems Sustainability at the University of Tasmania. He’s spent years researching how to create a degrowth model for the health industry—and why it will be better for people as well as our planet. Martin argues that the way we currently run our healthcare is another symptom of overconsumption, explaining when healthcare benefits and healthcare expenditure actually decouple.

This is a fascinating episode in which Martin interweaves the health of the planet’s body with our own, providing a vision for a sustainable, global healthcare industry which doesn’t depend on economic growth, inequality, or over-extraction. He explains we can save lives and prevent disease—but to stay within our planetary boundaries, we’re going to have to transform how we do that.

Women’s bodies have always been the cornerstone of reproduction. So has Earth’s. It’s why the enclosure and appropriation of both is fundamental to the accumulation of the capitalist class.

On this extraordinary episode, I interview Marxist-feminist scholar, Silvia Federici, author of Caliban and the Witch, a phenomenal book which articulates how capitalism did not naturally evolve from feudalism, but necessitated the violent displacement of women’s power in their communities and control over their own reproduction. We discuss this in the context of women’s rights being violated all around the world today as we enter a period of resource scarcity, and why it is therefore imperative that the Western feminist movement recover this analysis to create an effective resistance movement.

Ask anyone anywhere what’s the leading cause of global heating and they’ll tell you: fossil fuels. But what if we’re all wrong?

Gerard Wedderburn-Bisshop is a scientist for the World Preservation Foundation and worked as a Principal Scientist with Queensland Government Natural Resources, using satellite data to monitor three decades of vegetation cover and broadscale deforestation. In February 2025, he released a paper showing how the IPCC is using different models to calculate the emissions from fossil fuels and animal agriculture. Gerrard researches shows, when we use the same model for both, animal agriculture becomes the biggest driver of global heating.

In this episode, Gerard explains his research and other problems with emissions calculation, including how deforestation is disregarded and methane is misrepresented. He calls all of this inconsistent emissions accounting—and it could be leading policy-leaders astray.
