Can one person sailing solo around the world contribute to scientific knowledge? What happens when you encounter illegal fishing vessels in the middle of the ocean? How can we address the growing crisis of plastic pollution in our seas? In this episode, we dive into these questions with Bert Terhart, a scientist, explorer and entrepreneur who circumnavigated the globe alone on his sailing yacht, conducting citizen science along the way.

During our conversation, Bert shares his first-hand observations of environmental challenges facing our oceans, from illegal fishing fleets operating with impunity to the stark reality of plastic pollution. We discuss how he worked with researchers to track ocean currents, monitor microplastics and count endangered albatross populations during his journey. Bert offers a shocking statistic: for some commercially exploited species of fish, approximately 80% of the commercial catches are illegal or unregulated, highlighting how enforcement remains one of our biggest environmental challenges.

Beyond observations, we explore how individuals and businesses can engage positively with environmental issues. Bert emphasises the importance of persistence in creating meaningful change and discusses how new technologies, including AI, might help solve complex environmental problems. Despite the challenges, he remains optimistic about our future, believing that human ingenuity and our ability to adapt will ultimately outpace our capacity for environmental destruction – if we can combine good science with effective policy and consistent action.

Bert terHart, self-described as 'soldier, sailor, scientist, adventurer, serial entrepreneur and author', just seems to have a knack for knocking off the impossible. A Fellow of the Royal Canadian Geographical Society, Explorer in Residence for the BC Historical Society, Founder of the Canadian Interactive Waterways Initiative, CEO of LeadBrain.ai, and author of, among others, the children's book 'Sir Salty Goes to Sea', Bert has sailed solo, non-stop around the world, into the Bering Sea, and out to the Aleutian Islands all in an effort to follow in the wake of some of the world's greatest explorers and cartographers. In the same vein, he paddled solo, across Canada from the Pacific to Atlantic Oceans covering more than 7800kms by foot and canoe. What's coming next is even more extreme. Or crazy.

Bert terHart has had a life-long passion for the oceans and oceanography. With advanced degrees in math, physics and physical oceanography, he has studied the role the world's oceans and coastal seas play in moderating and regulating climate, nutrient productivity and pollution distributions, and salmon migration.

A career in academics, however, was not to be. Software engineering and business drew him away from the formal world of academia. Bert went on to create software and technical tools used by health care professionals in Canada, Great Britain, the United States, and Australia ultimately helping in the diagnosis and treatment of tens of thousands of patients.

His passion for the oceans has translated into more than 50,000 miles of blue-water sailing, almost all of it solo, and a keen advocacy for the citizen scientist in all of us. His programming and business skills have been sought out by the universities, professionals, and environmentally responsible businesses and corporations in Canada and the US.

His exploits have been featured both nationally and internationally on TV and in print. He's a frequent speaker to local business groups, libraries, museums, schools, and adventurers of every ilk.

I feel like this episode is the ultimate guide to understanding coexistence with wolves. Once again I talk with ecological anthropologist Thorsten Gieser, this time about his excellent book “Living with Wolves: Affects, Feelings and Sentiments in Human-Wolf Coexistence”. In the episode, Thorsten recounts a tense atmosphere during the visit to a wolf kill site. We also talk about understanding emotions that are sparked by wolves, and we discuss the recent decision to lower the protection status of wolves in the EU.

During our conversation, Thorsten draws from his extensive fieldwork across Germany where he witnessed firsthand the aftermath of wolf attacks on livestock. He explains the unique psychological impact wolves have on communities, stemming from both their distinctive hunting methods, which he describes in terms of "necroaesthetics", and centuries of cultural conditioning. We examine the political dimensions of wolf management across Europe and explore the often contradictory attitudes within hunting communities, who historically viewed wolves as competitors rather than fellow predators. Thorsten challenges common narratives, addressing how conspiracy theories about wolf reintroduction persist despite clear evidence of natural recolonisation.

Moving beyond practical considerations, we discuss Thorsten's concept of “affect-guided thinking” in wildlife management, an approach that acknowledges emotional responses without being driven solely by them. The discussion explores the “queasy feeling” many experience in wolf territories and the emotional resilience required for true coexistence. Rather than focusing exclusively on protection levels or culling quotas, Thorsten argues we must confront more fundamental questions: How do we distinguish between legitimate concerns and fear-mongering? What emotions should we cultivate to share landscapes with these controversial predators? And how might we develop the psychological capacity to live alongside animals that challenge our sense of control over nature?

Irish Whale and Dolphin Group and Irish Wildlife Trust.

This episode is part of the global Podcasthon initiative, in which podcasters worldwide dedicate one episode to their chosen charity. To maximise impact, all episodes are published in a single week. I’m showcasing two of the most influential Irish environmental charities: the Irish Whale and Dolphin Group and the Irish Wildlife Trust.

The conversation with Pádraig Whooley from the Irish Whale and Dolphin Group reveals the challenges facing marine life in Irish waters. Pádraig explains how they've expanded from focusing solely on sightings and strandings to include welfare issues for living stranded animals. He discusses alarming changes in whale behaviour, linking them to destructive fishing practices where large trawlers target vital forage fish that form the foundation of marine ecosystems. Pádraig emphasises that successful conservation would involve implementing bans on industrial-scale fishing in Irish coastal waters and establishing meaningful marine protected areas—not just 'paper parks' but properly managed conservation zones.

Kieran Flood from the Irish Wildlife Trust shares insights into one of Ireland's longest-established nature charities. Founded in 1979, the organisation focuses on protecting and restoring Ireland's natural heritage through education, advocacy, and developing nature reserves. Kieran explains that despite Ireland's green reputation, Irish biodiversity faces serious threats from intensive agriculture, forestry practices, and industrial fishing. The trust is currently focusing on supporting the implementation of the EU Nature Restoration Law, campaigning for effective marine protected areas through the Fair Seas coalition, and expanding their rewilding projects. He emphasises that perhaps the most important change needed is a fundamental shift in how people understand their connection to nature, recognising that humans are not separate from the natural world but an integral part of it.

Is it possible for humans and large carnivores to share landscapes without conflict? What happens when predators like wolves, bears, and lynx return to areas where they've been absent for centuries? How do we balance the ecological benefits of apex predators with the real concerns of rural communities and farmers? We’re trying to answer these questions with our returning guest Dr Jonny Hanson, author of ‘Living with Lynx: Sharing Landscapes with Big Cats, Wolves and Bears.’

Drawing on his unique background in both farming and conservation, Jonny brings a nuanced perspective to this often polarising topic. He recounts his experiences growing up in Malawi where wildlife existed alongside urban areas, and how this shaped his understanding of human-wildlife conflict. The conversation explores the urban-rural divide in attitudes towards large carnivores, with Jonny pointing out that 'everybody loves a large carnivore when it's somewhere else' – a phenomenon he calls 'biological NIMBYism.' We also examine how compensation schemes for livestock losses often fail to deliver the expected outcomes due to bureaucracy and delays, turning farmers with positive attitudes into fierce opponents of predator reintroduction.

In the episode, we also tackle difficult ethical questions about lethal control, the use of technology in managing human-wildlife conflict, and the philosophical meaning of "wildness" in our modern world. Jonny emphasises that while the ecological benefits of reintroducing large carnivores are important, we shouldn't overlook the emotional and philosophical dimensions – the sense of wonder that comes from knowing these animals exist in our landscapes, even if we never see them. We conclude the episode by attempting to predict if the reintroduction of predators to Britain and Ireland will happen in the coming decades.

Are offshore wind farms detrimental to marine mammals? What happens when we industrialise our seas with massive turbines? Can we balance the urgent need for renewable energy with protecting marine life? These questions take centre stage in our conversation with marine ecologist Dr Stephen Comerford, who is the ORE Marine Biodiversity Officer at the Irish Whale and Dolphin Group. Stephen has years of experience working with both the oil and gas industry and offshore renewables, which makes him the perfect guest to discuss this important topic.

In this episode, we discuss the critical issue of underwater noise during wind farm construction. Stephen explains how pile driving - the process of hammering massive steel tubes into the seabed - creates intense underwater noise that can harm marine mammals. However, there's hope in the form of various noise reduction technologies, from bubble curtains to innovative pile installation methods, though implementing these solutions comes with significant costs and technical challenges.

Looking to the future, Stephen shares his perspective on how offshore structures might create novel marine ecosystems and discusses the crucial role of citizen science in monitoring marine mammals. While acknowledging the environmental pressures our seas face, he highlights how Ireland's new focus on marine planning and management, driven by offshore wind development, could lead to better protection of our oceans. The episode offers a balanced view of how we can pursue essential renewable energy goals while safeguarding marine life.

What makes someone kill an animal and still claim to care deeply about nature? Can the act of hunting foster environmental stewardship? These somewhat provocative questions lie at the heart of my conversation with Thorsten Gieser, an anthropologist studying hunting practices and their deeper meaning in modern society.

Our discussion explores the complex emotional landscape of hunting and challenges common misconceptions about hunters taking pleasure in killing. Through personal accounts and research findings, Thorsten explains how the difficult experience of taking an animal's life, when approached mindfully, can lead to deeper environmental awareness and connection with nature. We also discuss how various factors, from hunting traditions to modern technology, influence the relationship between hunters and the natural environment.

Our conversation takes a turn when we discuss hunting rituals and their role in modern society. Rather than dismissing them as outdated customs, Thorsten explains their crucial function in creating space for reflection and processing the weight of taking life. We end the episode with a discussion about how hunters can better engage in public debates about their practice, suggesting that acknowledging the moral complexity of killing might lead to a more productive dialogue about conservation and our relationship with nature.

How to Get Started in Deer Hunting in Ireland

What happens when Pacific salmon invade Atlantic waters? How does a Soviet-era experiment from the 1950s continue to impact Norwegian rivers today? We’re answering these questions in conversation with Jude Isabella, founder and editor-in-chief of Hakai Magazine. This episode was inspired by her three-week journey along Norway's border with Russia, documented in her article ‘Where the Rivers Run Pink’. The article tells the complex story of pink salmon that have established themselves in Norwegian rivers after straying from Russian waters. Our conversation, however, goes beyond the article itself and reveals the details and stories that didn't make it into the article.

In our discussion, we explore Norway's evolving approach to managing this invasive species. While initial reactions focused on eradication, the situation has developed into a more nuanced strategy of population control. Jude shares insights about local initiatives to handle the influx of pink salmon, from volunteer-run fish traps to commercial processing operations, and how these invasive fish are becoming part of the local food chain.

We also examine the broader ecological implications of this invasion. While pink salmon are often viewed as a threat to native Atlantic salmon, Jude reveals surprising findings about their potential benefits to river ecosystems. The episode concludes with thought-provoking reflections on novel ecosystems and how we adapt to inevitable environmental changes in our rapidly transforming world.

Can hunting be an effective way to manage human-wildlife conflict? What happens when well-intentioned wildlife protection measures backfire? I spoke with Jens Ulrik Høgh, a Scandinavian hunting journalist, to find answers to these questions through the lens of Romania's bear management crisis. When hunting was banned in 2016 under pressure from animal rights groups, it led to an unexpected surge in human-wildlife conflict, with 300 people being mauled and 26 killed by bears that had lost their fear of humans.

Through many examples from Romania, Africa and Scandinavia, Jens explores how regulated hunting can serve as a vital conservation tool. He challenges common misconceptions about trophy hunting and explains how hunting tourism provides critical financial incentives for protecting wildlife habitats. We discuss how local communities in various parts of the world depend on hunting not just for wildlife management but also for economic sustainability. This highlights the complex relationship between wildlife conservation and local people's livelihoods.

The conversation concludes with an optimistic outlook on the future of hunting, supported by growing public acceptance. Jens also provides valuable insights into how hunters can better communicate about their activities, emphasising the importance of honesty, factual accuracy and sensitivity to others' feelings. His practical advice focuses on building bridges between hunters and non-hunters rather than creating further divisions.

This episode is a real treat for all those who are interested in bowhunting, bowhunting culture and the ethics of bowhunting compared to rifle hunting. Everything sprinkled with a healthy dose of hunting stories.

It feels like I’m one of the only very few who talks about bowhunting with European listeners in mind. Indeed, I would like to see hunting with archery tackle being legalised and popularised on the old continent. In my view, the notions that it’s inhumane or somehow unethical are ill-advised and plain wrong. It is especially disturbing when such unwise opinions are expressed with confidence by hunters or veterinary practitioners who have no experience or previous exposure to bowhunting.

To talk about these matters I’m joined by expert bowhunter Jim Clark. In our conversation, Jim shares a wealth of knowledge about bowhunting as well as some of his personal stories. As always I didn’t shy away from asking him hard questions to tease out the potential downsides of using archery tackle over firearms.

It was a thoroughly enjoyable conversation and it only made me want to try my hand at bowhunting even more. I will keep talking about hunting with archery tackle to at least provoke a constructive discussion among European hunters and hunting organisations alike. If you would like to see bowhunting legalised, please leave a comment. What are your thoughts?
