Madagascar Environment and Shark Science with Dr. David Ebert

Madagascar Environment is at the center of this engaging conversation with Dr. David Ebert, a world-renowned shark scientist and co-host of Beyond Jaws. In this episode, we uncover the unique challenges and opportunities that Madagascar’s marine ecosystems face, from biodiversity conservation to the pressures of unsustainable fishing. Shark science takes on a new dimension as Dr. Ebert shares his experiences conducting fieldwork in Madagascar and how these insights contribute to our global understanding of marine species. This episode brings together conservation, local community needs, and international collaboration to highlight why Madagascar’s environment plays a vital role in ocean health worldwide.

Vaquita stands as one of the rarest marine mammals on Earth, with fewer than 20 left in the wild. In this episode, we explore what the near-extinction of the vaquita teaches us about the future of sharks and why their survival is critical to the health of the ocean. Sharks play an essential role in keeping marine ecosystems balanced, yet they face many of the same threats that doomed the vaquita: bycatch, overfishing, and weak enforcement. This episode dives into the parallels, the urgency of acting before it is too late, and how the loss of sharks would ripple into every part of our lives, from food security to coastal protection.

Marineland beluga whales remain at the center of a heated national debate after Canada’s Department of Fisheries and Oceans denied the park’s request to export 30 whales to a marine theme park in China. In this episode, Andrew Lewin explores the unfolding crisis, from the park’s claims of financial hardship to the legal, ethical, and political questions surrounding the whales’ future. Marineland beluga whales could face an uncertain fate as the park warns it may not be able to care for them, raising the specter of euthanasia. Andrew breaks down government responses, animal welfare group actions, and emerging relocation proposals including the Nova Scotia Whale Sanctuary Project and Inuit-led plans. This episode unpacks the clash between law, profit, and responsibility while asking the essential question: who should ensure the whales’ welfare?

Shark conservation: All The Sharks brings you into the water with filmmakers and scientists, exploring how camera choices, site selection, and safety shape close encounters with tiger sharks, hammerheads, white sharks, and whale sharks. You will hear candid stories about reading shark behavior, managing lighting on fast passes from silky sharks, and turning footage into conservation wins that help real populations. Underwater cinematography: From South Africa to the Bahamas and Bimini, we compare scuba and freedive tactics, frame sharks without stressing them, and translate field lessons into science communication that actually moves people. The team breaks down filming ethics, bycatch and fishing pressure, and what Shark Week gets right and wrong, all to help the audience understand sharks and support smarter protection.

Marineland Beluga exports have been denied by Canada’s Department of Fisheries and Oceans, igniting national debate over animal welfare, legality, and ethics. In this episode, Andrew Lewin breaks down what the 2019 law banning cetacean captivity means, why DFO refused Marineland’s permit to sell 30 belugas to China, and what options exist for the facility and the animals now caught in limbo. Marineland Beluga care has become an urgent issue as the park claims it cannot afford to maintain the whales, warning of potential euthanasia without government help. Andrew explores whether Marineland should be required to care for the animals it profited from, or whether public intervention is necessary to ensure the whales’ welfare. This episode blends law, compassion, and marine science to uncover what ethical responsibility looks like when conservation meets crisis.

Sustainability business: In this episode of How to Protect the Ocean, Andrew Lewin talks with Lee Stewart about how businesses can make sustainability a practical, measurable part of their operations. They explore how carbon tracking, waste reduction, packaging design, and supply chain improvements can build resilience while cutting costs. Ocean literacy: Lee shares experiences from Australia, Tonga, and New Zealand that show how business practices directly connect to the ocean’s health. They also discuss the lessons learned from an international shipping case study in Malaysia that reveals how logistics and sustainability intersect. ESG reporting: The conversation focuses on keeping sustainability simple—using dashboards, certifications, and team culture to drive consistent progress. Whether you’re leading a company or just beginning your sustainability journey, this episode offers the clarity and motivation to start today.   Join the Undertow: https://www.speakupforblue.com/jointheundertow Connect with Speak Up For Blue Website: https://bit.ly/3fOF3Wf Instagram: https://bit.ly/3rIaJSG TikTok: https://www.tiktok.com/@speakupforblue Twitter: https://bit.ly/3rHZxpc YouTube: www.speakupforblue.com/youtube    

Mentors: climate change is hopeless—at least, that’s the message many young scientists are hearing from the people they were told to admire. But what if giving up isn’t the only option? In this episode, I respond to a heartfelt email from a marine science student who refuses to stay silent, even when senior scientists tell her that solutions to climate change are naive, misguided, or politically inconvenient. Mentors: climate change is hopeless may be the mantra of a tired system, but this generation of scientists has grown up under the weight of ecological crisis—and they’re ready to do something about it. I share concrete advice for early-career changemakers who want to be bold, build community, speak truth to power, and help people understand real climate solutions despite institutional apathy. If you’re frustrated, fired up, and looking for a way forward, this one’s for you.

Jane Goodall transformed the way we understand animals, conservation, and our place in nature. In this special tribute episode of How to Protect the Ocean, I reflect on Dr. Goodall’s incredible legacy and what her life’s work teaches us about empathy, science, and hope. From living with chimpanzees in Gombe to influencing ocean storytelling today, her impact spans generations and ecosystems. Jane showed us that animals are not resources, but individuals with emotions, intelligence, and culture. She taught us to listen, to observe, and to act. Jane Goodall’s work didn’t end with primates. Her vision of conservation included youth, community, and global collaboration. She helped shape marine and terrestrial protection efforts, inspired countless scientists (especially women), and changed how we use emotional connection to inspire action. Even at 91, she was on a speaking tour, still using her voice to make the world better. This episode unpacks what she gave us and how we carry that legacy forward especially in ocean conservation.

Explore the ocean floor is more than a scientific ambition, it is a global necessity. In this episode of How to Protect the Ocean, Andrew Lewin speaks with Tim Kearns, Executive Director of Map the Gaps, about the upcoming Ocean Floor Explorer conference in Victoria, BC. They discuss why mapping the seabed is vital for science, conservation, and society, while uncovering how challenges like funding and technology can be turned into opportunities for global collaboration. Mapping initiatives are not only about science but also about storytelling, communication, and inspiring action. Andrew and Tim highlight how diverse communities can play a role, from students and researchers to policymakers and entrepreneurs. The conversation explores how events like this conference bring people together to tackle some of the biggest challenges in deep-sea exploration while building networks that fuel long-term solutions.

Fighting overfishing with AI is transforming how we protect the ocean. A new study revealed that nearly half of all coastal marine protected areas (MPAs) showed fishing vessel presence, with many ships operating “dark” without AIS tracking. This means that even in places meant to be safe havens for biodiversity, industrial fishing has been creeping in unnoticed. Satellites and artificial intelligence are changing that reality. By detecting untracked vessels and guiding patrols, this technology is already leading to arrests in Gabon, better enforcement in Palau, transparency in Chile, and effective oversight in the UK Blue Belt program. In this episode, I’ll break down the science behind the study, the risks remote MPAs face, and the real-world success stories that give us hope.
