Conservation and Science

How do you tell solid science from something dressed up to look like it? Are we living through the sixth mass extinction? And why is the climate crisis not the worst of the planetary boundaries we have crossed? My guest today is Amy McEuen, a professor of Biology at the University of Illinois Springfield, where she has taught environmental biology, ecology and conservation biology for more than twenty years. Her book, 'How to Think Like an Ecologist: A Non-Scientist's Guide to Saving Our Planet', is written for people without a science background and is laid out like a field guide, so you can read the chapters in any order you like. What caught my attention is that Amy spends the opening chapters on what science actually is and on how misinformation works before she gets anywhere near ecology. Our conversation follows much the same path.
We spend a fair bit of time on that groundwork because I think it matters a lot. Amy explains the difference between misinformation and disinformation, why fact checkers read laterally rather than arguing with an article line by line, and why prebunking works better than debunking. From there we move on to nature itself. If humans are part of nature, does the word still mean anything useful? Amy also argues that we get further by asking people what they value about a particular place than by asking them to defend nature in the abstract. We also pull apart the idea of a historical baseline, since choosing a date to restore the land to is a fairly arrogant thing to do and not much use when the whole global environment is shifting.
Then we get to the numbers. To qualify as a mass extinction, 75% of taxa have to disappear from the planet, and Amy explains why the honest answer to 'are we in the sixth one?' is both yes and no. We also talk some more about planetary boundaries and why biodiversity loss and novel entities such as plastics and synthetic chemicals are worse than climate change, even though climate takes up most of the oxygen in the room. We finish with talking about policy, paradigms and eco-anxiety. Is policy change enough on its own or does something have to shift in how we see the world? And how do you talk about any of this without either frightening people into switching off or offering false comfort?

Why do we feel so hopeless about the future of the natural world? Is nature really collapsing everywhere we look or have we simply been told a one-sided story? And what if our lack of control over ecosystems turns out to be our greatest strength? In this episode I welcome back expert ecologist and author Simon Mustoe to talk about his new book, ‘How to Survive the Next 100 Years: Lessons from Nature’. It picks up where his previous book left off, building on the idea that we are not separate from nature but central to it. Simon explains how we sit right in the middle of the trophic pyramid and depend entirely on the animals around us to keep energy moving through the systems that sustain life. It is a perspective that quietly reframes how we think about our place on this thin, living veneer of the planet.
Much of our conversation focuses on balance, both in nature and in how we talk about it. Simon points to a reanalysis of the Living Planet Index suggesting the picture is closer to fifty-fifty than the widely reported three-quarters decline, with many animals, including large ones like humpback whales, recovering on their own. We get into why bad news spreads so easily while good news gets buried and how our understanding of the world often lags decades behind reality. From novel ecosystems and so-called invasive species to the misuse of words like 'pest' and 'overabundance', Simon makes the case for caution, humility and a kind of Hippocratic oath for conservation: first, do no harm. He argues that forcing outcomes rarely works, because the forces shaping ecosystems are far more powerful than we are.
We also explore why blanket solutions so often fail, using examples from Australian farming, koala conservation and a single burrowing animal that increased the profitability of a sheep farm. Simon believes communities, not top-down policy, hold the key to lasting change, and that real progress comes from enabling people to act locally rather than shouting at politicians or each other. He leaves us with simple, practical advice: get outside, pay attention to the nature on your own doorstep, support what others are doing nearby, and step back from the relentless flow of negative news. It is a refreshingly balanced, middle-of-the-road conversation that gives you something rare these days, a genuine sense of agency.

What if the environmental movement has badly underestimated our ability to solve the climate crisis? Could renewable energy grow so fast that we are out of fossil fuels within a decade? And once emissions fall away, how do we deal with the carbon already in the atmosphere? In this episode I'm joined by Benoit Lambert, author of the book titled ‘Biogeotherapy: nature-based climate solutions, life as a geological healing force’. Benoit has a rich and varied background, from planting four million trees by hand across five Canadian provinces to spending eighteen years in Geneva, where he completed a PhD and worked as French editor for the Worldwatch Institute. He argues that reducing emissions, while essential, is only half the task. We also need to capture and store carbon dioxide, and nature offers the tools to do exactly that.
Much of our conversation focuses on the four pillars Benoit sees in nature-based solutions: regenerative agriculture with cover crops and no-till methods, carbon ranching through holistic grazing, massive reforestation, and biochar. He explains how the world's soils have lost a great deal of their carbon and why putting it back, with proper science behind it, can fix the problem faster than most people imagine. Benoit is honest about the friction within the green movement too. He describes losing friends over these ideas, and reflects on why so many who spent decades defending degrowth react with hostility when shown that solar and wind have followed a path nobody expected. It's a frank look at how worldviews get tangled up with identity.
We also talk about the people, like Tony Seba, who did predict the speed of the renewable transition and why exponential change is so hard for us to grasp. Benoit shares practical steps ordinary people can take, from supporting regenerative farming to using biochar in their own gardens. Throughout, his message is one of grounded hope: the science of soils has moved on enormously since 1992, the financial levers exist, and a solar economy paired with nature could give us prosperous, healthy societies for centuries to come. Whether you lean optimistic or sceptical, this is a conversation that will challenge how you think about what's actually possible. And yes, it might involve cycling to work.

Why are red deer populations in Germany growing in number and antler size yet sitting in deep genetic trouble? What is the difference between census population size and effective population size, and why does it matter? And how can a satirical award for the worst-built wildlife crossing draw attention to the issue of habitat fragmentation? In this episode, I sit down with Frank Zabel, a wildlife biologist, campaigner, and co-host of the award-winning JAGDcast podcast. Frank also runs the nonprofit RotWildes Deutschland (Non-profit Society for Wildlife Biology & Sustainable Use) and authored the 2022 deer management plan focused on corridors and mapping. Although Frank is speaking from Germany, many of the issues he raises will feel familiar to anyone interested in deer management, habitat connectivity, and how policy decisions made decades ago continue to shape what happens on the ground today.
Frank takes a broader view of red deer as an umbrella species, using them as a vehicle to talk about biodiversity in general. We discuss the historic genetic bottleneck created when red deer were extirpated in much of Germany after the 1848 revolution and how that legacy still shapes populations today. Frank explains why most German red deer populations now sit dangerously close to or below the threshold where the issues with inbreeding start to appear, even though the absolute numbers look healthy on paper. Our conversation also covers the red deer management areas in southern Germany, where deer must be shot once they leave designated zones, a policy decision rooted in post-war food production priorities that has become, in Frank’s words, a far more effective form of habitat fragmentation than any motorway.
We then shift gears to the lowering of the wolf’s protection status in the EU. Frank offers a perspective that may surprise some listeners, particularly those who expect hunters to take a predictable line on the wolf question. He also makes a compelling case for why looking at wolves across the whole of Europe through a single lens misses what is actually happening on the ground in different regions. We touch on what hunters need to do when wolves return to an area, and Frank shares an observation from his time in Sweden that illustrates the point well. This is a rich conversation packed with wisdom and insight.
