Ep. 051: WTF is the Polycrisis and why should I care?

In this conversation, we update you on two big milestones for the Grange Project, the launch of the Welsh Rewilding Alliance and our OECM recognition, before sitting down with Professor Mike Berners‑Lee.

We ask Mike to explain the polycrisis: how climate change, biodiversity loss, pollution, food insecurity and geopolitical instability are all interlinked. Mike helps us see why recycling alone won’t cut it: plastics are produced almost entirely from fossil fuels, their emissions could eat up a large chunk of the remaining carbon budget and their additives disrupt hormones.

We also talk about why technology by itself isn’t enough, how misinformation slows progress and what practical steps we can all take-like switching to trustworthy media and supporting a national information campaign to wake up and act.

Episode journey:

[00:05] Introduction and mission. We open the show by explaining why we started the Wilder Podcast: to share our learning about rewilding and the wider forces shaping our world. We remind listeners that we created the Grange Project two and a half years ago to restore nature, grow food, support eco‑businesses and reconnect people with land.

[02:24] Two big updates. We proudly announce the launch of the Welsh Rewilding Alliance and its report A Welsh Way to Wild. We also share that the Grange Project has been recognised by the Welsh Government as an OECM, a big step in confirming that our land management has rigorous governance and real biodiversity benefits.

[07:08] Introducing Professor Mike Berners‑Lee. We explain how we first encountered Mike’s work-reading There Is No Planet B inspired us to buy the farm and start the Grange Project. Mike introduces himself as a professor, consultant and author.

[11:09] What is the polycrisis? Mike explains that the polycrisis is a tangle of interconnected challenges driven by humanity’s unprecedented power. He emphasises that disasters like pandemics and wars no longer happen in isolation; their severity comes from the cascading effects they unleash. For us, it was eye‑opening to see how our economic and political systems amplify these stresses.

[16:58] Examples of cascading crises. We discuss real‑world examples: the COVID‑19 pandemic and the war in Ukraine amplifying food and energy crises. Mike highlights that plastic production has boomed since the 1950s and plastics are a major source of emissions and endocrine disruption. It reinforced for us how everything is connected.

[20:43] Wake‑up call and the National Emergency Briefing. Mike tells us about the National Emergency Briefing in Westminster, where experts covered nine dimensions of the crisis from health and food to national security and no one thought the situation was exaggerated. We both feel this shows how widely the severity of the crisis is recognised and why we need national action.

[23:05] Misinformation and media ownership. We explore how misinformation is blocking progress. Mike challenges the narratives that climate action will leave us poorer and colder, and explains how social‑media algorithms spread disinformation. We urge you to choose trustworthy news sources and recognise manipulation.

[29:14] Techno‑optimism vs. systemic change. Mike says that simply scaling up renewables isn’t enough. He points out that although renewable capacity has grown massively, fossil energy use has also climbed, so overall emissions keep rising. That’s why systemic measures like carbon pricing and fossil‑fuel constraints are critical.

[33:35] Human psychology and leadership. Together we discuss why people aren’t inherently selfish. Neuroscience and social history suggest we can cultivate cooperation and empathy. Mike encourages us to seek leaders who are kind and honest, and we talk about the courage it takes to speak up and push for change.

[47:19] Calls to action. We finish by encouraging you to sign the letter at nebriefing.org, host local screenings of the briefing film and start conversations in your community. Mike notes that facing these issues head‑on feels liberating, we felt it too.

[49:05] Host reflections. After the interview, we reflect on our own nerves and gratitude for Mike’s clarity. We discuss doing a mini‑series on the individual crises and debate whether information alone prompts action. We conclude that people need both facts and relatable stories of hopeful change.

Why this episode matters

As rewilders, we see how climate change, biodiversity loss, pollution, public health and social instability are woven together. This episode shows that tackling one issue in isolation isn’t enough we need to change the systems that drive multiple crises and challenge misinformation. By combining big‑picture analysis with concrete steps, from signing a letter to choosing better media, we hope to inspire you to join us in building a more hopeful, resilient future.
