Recent events have brought to the surface how vulnerable Australia is to energy shortages with only 30 days of stockpiled oil reserves. Within the context of these tentative times, it is important that we re-explore alternative options. Scott Witheridge is an Environmental Engineer and Author of the book "The Post Fossil Fuel Era". The book is a deep investigation into the next frontier of energy—exploring decentralised power, hydrogen innovation, and the intersection of conventional and emerging technologies. In this interview, Scott discusses the possibilities of abundant, perpetual and non-conventional energy.

The clock is ticking as we face an imminent agricultural crisis. It is likely that we only have around sixty global harvests left until the world's top soils are depleted. Regenerative agriculture offers many potential and practical solutions toward a more sustainable relationship between food production and environmental stewardship. However, sustainable farming is a broad church with many different and sometimes contradictory methodologies, from mob cattle grazing to veganic farming practices to precision fermentation. Which ones do we choose?

Louis De Jaeger, author of “SOS: Save Our Soils”, asked this question as he travelled the world to explore the whole gamut of regenerative farms and land management practices. Louis’ holistic, non-judgemental and open-minded approach is very refreshing. As far as we’re aware, he is the only person who has managed to endorse veganic farming while also enjoying an enthusiastic introduction to his book by Allan Savory, figurehead of the holistic grazing movement. Louis concludes that all regenerative farming methods have their place, depending on context, so long as the soil is kept healthy with its precious microbiome intact.

In this episode of PGAP, we’re joined by Michael D.B. Harvey, author of The Age of Humachines: Big Tech and the Battle for Humanity’s Future. Harvey offers a sobering perspective on the trajectory of modern technology - not towards a Star Trek-style utopia but into a hyper-neoliberal, corporate-driven dystopia shaped by Big Tech. His analysis strikes a chord with the Post-Growth community, which has long challenged the illusion that technology alone can rescue us from our social and ecological crises.

In this latest episode we speak with scientist, researcher, and author George Tsakraklides about the deeper roots of humanity’s many crises. Drawing on his rich scientific background and corporate insight, George explores how our evolutionary wiring, societal structures and cultural narratives hinder meaningful change. We unpack the psychological forces driving self-destruction, the limitations of rational thought and the need to reconnect with a deeper sense of being. From the inherited challenges of activism in a world of algorithms to the quiet strength of grounded action and grief, this conversation offers a powerful lens on navigating despair and cultivating meaning in a collapsing world.
