Polar Bears in a Warming World with Andrew Derocher

Listen to my conversation with John Aitchison from the Coastal Communities Network Scotland to learn about the devastating effects of salmon farming on the marine environment and coastal communities. Toxic waste, pesticides, diseases and parasites are just the tip of the iceberg.I knew that salmon farming was bad but I didn’t realise quite how bad it really is. Salmon aquaculture creates massive ecological and welfare issues for the fish. Both farmed fish as well as wild fish populations are negatively affected by open-net aquaculture. And that is even before I mention the impacts the industry has on coastal communities. The massive amounts of toxic waste, misuse of pesticides, diseases and spread of parasites that negatively affect wild salmon are just the tip of the iceberg.To better understand the issues examined in this episode, I talk with John Aitchison. John is an acclaimed wildlife filmmaker but he is also an environmental activist at the Coastal Communities Network Scotland NGO. During our conversation, we take a closer look at the Scottish salmon farming industry. However, the issues we discuss apply equally to Ireland, Norway or anywhere salmon aquaculture is present.I am pretty sure that after listening to this episode you won’t buy farmed salmon again, which you shouldn’t, or you will at least take a pause and consider your choices.Cover image courtesy of Corin Smith - copyrightSpecial guests in this episode: Ireland on the Fly Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Recommended Books: tommysoutdoors.com/booksMerch: tommysoutdoors.com/shopFollow Tommy's Outdoors on Twitter, Instagram, YouTube, TikTok and FacebookMentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

Do you feel climate anxiety? Is it overwhelming you? How do we find peace while being bombarded with dire environmental predictions? In an attempt to answer these questions, I talk with Lynne Sedgmore, a well-known educator, leadership coach, activist and the author of the book "Presence Activism: A Profound Antidote to Climate Anxiety".To set the scene, we start with a discussion about peaceful but disruptive climate protests. We discuss their effectiveness, the reception by the wider public, and the recent governmental clampdown resulting in excessively long prison sentences for protesters. I also asked Lynne about ways to communicate with older generations about environmental issues. From my observations, it's usually more difficult than with younger people.During our discussion, Lynne talks about the challenges of immersing herself in climate change literature and the importance of finding a balanced perspective. As in the book, in the podcast we explore the concept of "presence" as a tool for managing anxiety, and how practices like meditation have a calming effect on our nervous systems. Lynne emphasises the need for empathy in climate discussions, even with those holding opposing views.We finish with a reminder about the value of staying present, rather than getting lost and upset by predictions for the future. This episode offers a unique mix of practical advice and philosophical wisdom for anyone grappling with climate concerns.

Last week I published a blog post where I set out to answer the question of whether polar bears are facing impending extinction due to climate change or are they, in fact, doing better than ever. Around the time when I was investigating this question, I got in touch with Professor Andrew Derocher from the Department of Biological Sciences at the University of Alberta, who has studied polar bears for over 40 years. He specialises in ecology, conservation, and management of large Arctic mammals with a particular focus on polar bears. So, of course, I couldn’t miss the opportunity to sit down with him for a comprehensive chat about all things polar bears.During our conversation, we talk about the limiting and regulating factors of polar bear populations. Those include habitat use, predator-prey relationships, the effects of climate change as well as the accumulation of toxic chemicals in the bears' bodies. We also explore the issue of polar bear hybridisation with brown bears and how this might impact their population. We ended our conversation with an attempt to predict the future of polar bears in the rapidly warming world.You may also be interested in checking out my blog: “Are Polar Bears Going Extinct or Are Their Populations Doing Better Than Ever?”Finally, you might want to check Andrew’s book: “Polar Bears: A Complete Guide to Their Biology and Behavior”.

Is scientific publishing broken? How can we make it more accessible and inclusive? And what if peer review could be collaborative and efficient instead of opaque and burdensome? In this episode, we dive into the world of academic publishing with Dr David Green, founder of Stacks Journal. We talk about how the current system is failing researchers and science enthusiasts alike, with over half of all research never getting published and exorbitant costs imposed by a handful of publishers who monopolise the industry.David describes how Stacks Journal is revolutionising peer review through a community-based, transparent approach that empowers scientists by eliminating gatekeepers, reducing bias, and making publishing affordable. We also explore known issues like the publish or perish culture, resistance to paradigm-shifting ideas, and the impact of AI on academic writing. Finally, we try to answer the question of whether science really progresses one funeral at a time.This episode offers valuable insights into the changing landscape of scientific publishing. David shares his vision for the future of open access and provides inspiring advice for early-career researchers feeling discouraged by the system. Whether you're a seasoned academic or simply curious about how scientific knowledge advances, this episode is a must-listen.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Recommended Books: tommysoutdoors.com/booksMerch: tommysoutdoors.com/shopFollow Tommy's Outdoors on Twitter, Instagram, YouTube, TikTok and Facebook

The European Commission is deliberating on lowering the protection status of wolves in the EU. It seems like this decision has been taken after the European Commission president, Ursula von der Leyen’s pony was killed by wolves. Is this really the reason for what many have dubbed “a new European wolf hunt”? To unpack this issue I talked to environmentalists, farmers, top-tier scientists and last but not least, hunters.Our guests are a wildlife biologist, Professor John Linnell, a goat breeder, Bruno Lecomte, a social scientist, ​​Professor Erica von Essen, an environmentalist, the Head of EU Policy at BirdLife International, Ariel Brunner and, last but not least, the Secretary General of the European Federation for Hunting and Conservation, Dr David Scallan. Special thanks to hunting journalist and blogger Denis Plat for his help in ensuring that opinions from rural France were voiced.While making this episode I recorded many hours of material and understandably not all of it made it into the episode.

This is one of the most thought-provoking books I have read. Although I don’t agree with everything in the book, I can overlook my disagreements because of how brilliant some parts that I do agree with are. So I couldn’t wait to sit down with the author, expert ecologist, Simon Mustoe for a chat about his views and, of course, about the book.In his book, “Wildlife in The Balance”, Simon lays out the case for animals being the most important ingredient of the ecosystem. He outlines the critical importance of keeping the planet’s energy inputs and outputs in balance and the role animals play in ensuring this balance. This connection of ecology with physics is one of the most unique and forward-thinking aspects of this book. To extend this thought, it contains one of the most comprehensive and compelling explanations of why the climate crisis and biodiversity crisis are in fact one and the same — neither can be solved separately.After reading this book, I started to question many things that I had thought to be unequivocally true. For example, the removal of overabundant species, like deer, that are thought to be having a negative effect on the local ecosystem. I’m not saying that I think it’s not true anymore, but it made me question whether it is really true.Buy "Wildlife in the Balance" here.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Recommended Books: tommysoutdoors.com/booksMerch: tommysoutdoors.com/shopFollow Tommy's Outdoors on Twitter, Instagram, YouTube, TikTok and FacebookTommy’s Outdoors is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk Mentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

Are humans part of nature or separate from it? How do we define native species, and should we always strive to eradicate invasive ones? Can urban green spaces play a role in addressing climate change and biodiversity loss? And what is the Anthropocene anyway? These are only some of the questions I discussed with Dr. Marcus Collier, an Associate Professor of Sustainability Science at Trinity College Dublin. His expertise in nature-based solutions gives us a new perspective on answering these complex questions and a fresh approach to environmental issues.In this episode, we talk about the fascinating world of novel ecosystems. We explore the complex relationship between humans and nature while challenging traditional notions of ecosystem restoration and conservation. I asked Marcus to clarify the concept of the Anthropocene and its implications for our understanding of the human impact on the environment. We also didn’t shy away from the controversies surrounding invasive species and ecological restoration practices. Marcus shares his insights on how our perception of time and history influences our approach to ecosystem management and highlights the challenges of defining a "natural" state in an ever-changing world.Then our conversation shifts to cultural landscapes and urban environments, highlighting the importance of nature-based solutions in cities. Marcus emphasises the benefits of urban greening initiatives, from improved air quality to enhanced mental health, while acknowledging potential drawbacks like gentrification. He advocates for a multifaceted approach to environmental challenges, emphasising the need for both technological and nature-based solutions for issues such as water quality and climate change.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Recommended Books: tommysoutdoors.com/booksMerch: tommysoutdoors.com/shopFollow Tommy's Outdoors on Twitter, Instagram, YouTube, TikTok and Facebook
