This week I’m joined by James Dyke, a senior lecturer in Global Systems at the University of Exeter. James reveals why net-zero targets for carbon emissions do nothing but provide an excuse to continue business as usual, posing an existential threat to humanity. He goes into great detail about the interplay of politics, economies, culture and the industrialisation connecting us all, explaining that while there is no one quick fix to the climate crisis, decarbonisation is possible—if we get rid of fossil fuels.

We need to live differently. Part of that means learning how to live together differently, both with each other, and with the wider environment around us. 
 James Bullen is the founder of the Land-Based Living Collective, a UK initiative aiming to create accessible, land-based communities that provide economic opportunities for the residents, nurture the land back to health, foster a sense of community and tackle some of our biggest modern problems such as food insecurity, energy insecurity and financial precarity. James has spent much of his adult life living in alternative land-based collectives like this, and is honest about the challenges of such a life—and also the great wonders it offers. His vision is grounded in meeting material needs, interweaving existing solutions to create an ecosystem of resilience that can both support its residents and facilitate them supporting one another.

FROM THE ARCHIVES:
So much of the hope we put in solutions for climate change falls away under a microscope. Did you know wind turbines aren’t recyclable, for example? Guess where they’re buried. Are enough people thinking about what happens when globalisation fails and post-industrial states like Europe and the US are left to mine their own materials? How can we mitigate climate change, truly, without plunging billions into poverty?
Simon Michaux is working to find solutions to all these questions. As an associate professor in the circular economy solution unit at the Geological Survey of Finland, Simon models the mining and energy industries to figure out what we can do sustainably—and what is nothing more than greenwashing. He drops more than a few bombshells throughout this episode concerning energy use and politics, but also reveals a new energy paradigm he’s working on that could provide genuine zero emission energy.

Climate Vanguard is a youth-led organisation providing political education to the public and activists across the Majority World. I'm joined by Inea Lehner, one of their core team members, to discuss their outreach, strategies and principles in supporting the climate movement, and Leftist movements more broadly.
Wonderfully, this conversation explores how Inea's own life has been changed through political education, particularly through her adoption of a materialist lens. She explains how Marxism helped her make sense of the world, and what it has to offer the youth of today in their quest to dismantle the inequities of capitalism and create a new vision for a better future. This vision is centred on political decentralisation, social infrastructure and, of course, the regeneration of Earth's body—which is all possible, she says, if we learn to build power from the ground up.

FROM THE ARCHIVES:
Professor Steve Keen was one of the few economists to realise that a serious economic crisis was imminent in 2005. He publicly warned the world, and helped his native Australia navigate the 2008 crash without the major repercussions that crippled markets everywhere else.
He is now working on a new model of economics for a post-crash world. He joined me today to discuss why and how capitalism needs to be constrained, the economics of climate change and what mainstream economists and academics are getting wrong—to the detriment of us all.

Non-native species management has very little to do with ecology and everything to do with economics. That's what activist and writer, Clare Follmann, uncovered in her book Scapegoat: What the Invasive Species Story Gets Wrong (UK version, US version). She joins me to explain how "invasive" species have been blamed for creating the conditions of environmental degradation — conditions that have actually been caused by capitalism, extraction and colonialism.
In this fascinating episode, she reveals the linguistic tricks at play which colour the doctrine of invasive species management, and the insidious links between these protocols and racism and xenophobia. She gives illuminating examples of how extractive industries have blamed species for the problems caused by their pillaging of Earth, and emphasises that the very idea of non-native species forgets the diverse history of the planet which has seen species spread out all across the globe for millions of years.

Can violence be cured?
According to physician and epidemiologist, Gary Slutkin, it can. Gary worked for decades treating some of the most virulent disease outbreaks around the world. Then he took that model and applied it to his hometown of Chicago to treat what he believed was an outbreak of violence. His results were shocking: by implementing similar strategies to disease containment and treatment, violent crime could be dramatically reduced.
He joins me to discuss exactly that, explaining the research revealed in his book, The End of Violence (UK version, US version), which argues that violence is a pathogen, a contagion, which we can eradicate through tried and tested methods. Gary walks us through the exact methods he and his team at Cure Violence Global has used around the world to inhibit violence, and we discuss the particularities of sexual violence, state violence, and the absolute necessity of understanding that the epidemic is truly a crisis of male violence.

In an age of bad news, it is so important to remember that everything we need to remake the world is already with us. From how we produce food to how we organise our political systems, the solutions we need have long been developed and tested. What we need now is political will and community vision—and to hold onto the fact that everything is still worth fighting for.
Acclaimed author and integrator Jeremy Lent has spent the past years researching a vital book which explores how we can reform and revolutionise our most critical sectors, from finance to agriculture, in order to build a true ecocivilisation. Ecocivilization: Making a World that Works for All (US version, UK version) is a hopeful testament to both our past and our future, illustrated with real-world examples throughout the ages which show time and time again just what we are capable of when we put our minds and hearts together. On this episode, Jeremy walks us through his research, emphasising that such reforms would transform our relationships with each other and the wider world. This is a beautiful conversation which explores how we create the conditions for live to thrive—today, tomorrow, and for the rest of time.

What is the role of art in any crisis? To understand what is and to imagine what could be; to transcend and birth and promise.
This is the message of today's guest, David Farrier.  David is a professor in literature and the environment at Edinburgh University, and the author of Nature's Genius: Evolutions Lessons for a Changing Planet (UK version, US version). He joins me to discuss poetry, literature, relationality, language and intelligence. In this wide-ranging and meditative conversation, we discuss how space and time are made between species, how the entire world is evolving with and through the crisis, and what we can learn from Nature herself to meet this moment exactly where we are.
From the Enlightenment to whale song, this conversation explores just how critical art is in a moment of breakdown to be a vehicle for transformation, for transmutation, and, perhaps most importantly, daring—mirroring Nature's very own life force.

 What can we actually do if we want to achieve real change?
We have been sold a comforting lie that our purchasing power is the best way to change the world. But rather than offer anything substantial, this lie promotes a myth of individual responsibility that actually inhibits the drastic structural change we desperately need. 
Michael Maniates is an environmental social scientist working on issues of environmental governance, sustainable consumption, and sociotechnical change, and the author of The Living Green Myth: the Promise and Limits of Lifestyle Environmentalism (UK version, US version). He joins me to discuss how we were sold that big green myth, how it relates to the global neoliberal overhaul of the role of markets in the 80s, how it frustrates structural change, and what we can do instead. He also reveals the social science on how people react when their attempts to change the world through this very process are repeatedly frustrated—and how this impedes future action.
