  • Stefanie Brendl - Why sharks don't need your love

    For those who know me, my lifelong passion for the ocean and for sharks in particular can sometimes be let's say... overwhelming๐Ÿ˜Š. So, this conversation with Stefanie Brendl meant a lot to me. In this episode, she walks us through how Shark Allies pioneered a trade-based approach to shark conservation, starting with the landmark Hawaii shark fin trade ban in 2010 and sparking a global wave of legislation that followed.


    We discussed:

    โœ… What it feels like to be surrounded by tiger sharks in the open ocean

    โœ… How the image of sharks in the media has evolved although protection still lags behind

    โœ… Why blaming Asian demand is just the tip of the iceberg with the whole world supplying shark fins and pointing fingers at China

    โœ… Why the EU still permits shark fin trade in 2026 and supplies 40% of the Asian demand and what Shark Allies do about it


    ๐Ÿ—ฃ๏ธ ""The whole world is happily supplying shark fins and then pointing at Asia saying, 'You guys are the bad guys.'"


    A huge thank you to Stefanie for joining us and for fighting every single day for stronger shark protection worldwide. This episode was special. ๐Ÿ‘‰ The fight isn't over. More than 1.1 million citizens signed #StopFinningEU โ€” add your voice: https://stop-finning-eu.org/

    I really loved our last conversation with Will Gertler, CEO of Kumbatia Seafood. Will and his team are striving to demonstrate that market-based conservation solutions can actually work in the field.ย  In Blue Builders' last episode, Will explains in detail how he built Kumbatia Seafood training artisanal fishers and connecting them to international premium markets to boost their revenue while improving the sustainability of their fishing practices.

    With 60% of coastal Kenya living in poverty, marine conservation often comes at the expense of economic livelihoods. But what if access to premium markets could drive both income growth AND marine ecosystem recovery?

  • Marine Conservation Institute - Are marine protected areas really effective?

    ๐ŸŽ™๏ธ ๐—˜๐—ฝ๐—ถ๐˜€๐—ผ๐—ฑ๐—ฒ #๐Ÿฑ ๐—ผ๐—ณ ๐—•๐—น๐˜‚๐—ฒ ๐—•๐˜‚๐—ถ๐—น๐—ฑ๐—ฒ๐—ฟ๐˜€ ๐—ข๐˜‚๐˜ ๐—ก๐—ผ๐˜„! ๐ŸŒฑ๐Ÿ’™


    At UNOC3 back in June, momentum toward protecting marine ecosystems gained ground with global marine protected area coverage rising from 8% to 10% as countries like Tanzania, Colombia, or French Polynesia announced new MPAs. But as these numbers grow, a fundamental question emerges: how effective are Marine Protected Areas in actually protecting our oceans?


    We're addressing this concern head-on with this 5th episode of Blue Builders in which we speak with Lance Morgan (President) and Sarah O. Hameed (Director of Blue Parks) from the Marine Conservation Institute who have been advocates for effective marine protection from the early days.

    โœ… The gap between political announcements and ocean reality - why governments love MPAs that don't actually protect

    โœ… Why reaching 30% ocean protection by 2030 requires authentic community-led engagement

    โœ… The Cabo Pulmo transformation - how community leadership turned a depleted ecosystem into one with 400% biomass increase

    โœ… My 7-year-old burning question: did Lance really see the Titanic during his submarine missions in the deep?


    Lanceย and Sarah'sย 30 years of experienceย shows that when MPAs are designed with local leadership, they don't just preserve biodiversity - they enhance fishing opportunities outside park boundaries and create sustainable livelihoods.

    ๐ŸŒŠ๐Ÿ ๐ŸŒIn this new episode of the Blue Builders Podcast, I sit down with Markus Knigge, who shares his insights from years of working in conservation funding and project implementation across multiple continents.

    This conversation explores the delicate balance between challenges and hope in environmental conservation work - from witnessing climate change impacts firsthand to seeing the transformative power of well-directed funding and strong partnerships.

    We notably discussed:

    โœ… How global ocean commitments translate to real action on the ground

    โœ… Why funding only works with the right local partners to drive change

    โœ… What actually makes Marine Protected Areas effective, not just lines on a map

    โœ… Key expectations for the upcoming UN Ocean Conference in France

    โœ… Honest assessment of which local conservation successes can truly scale

    Markus's perspective on viewing conservation like a chess board - where every organization is just one piece in a larger strategy - offers a compelling framework for

  • Tom Hickey - Advancing Coastal Wetlands Conservation

    In this first episode of Blue Builders, we sit down with Tom Hickey, Project Director at The Pew Charitable Trusts, to explore the vital role of coastal wetlands in ocean conservation and climate action.


    Tom shares his personal journey โ€” from summers spent fishing off the coast of Cornwall to leading global efforts to integrate mangroves, seagrasses, and salt marshes into national climate strategies. We dive into how these ecosystems serve as powerful tools for both carbon mitigation and community resilience, and how countries can include them in their climate pledges through the Paris Agreement framework.


    Throughout the conversation, we explore:

    • Why blue carbon is a useful policy tool, but not the whole story
    • How local partnerships, community engagement, and language shape effective conservation
    • What it takes to map, manage, and restore ecosystems across very different national contexts
    • The challenge of scaling conservation solutions without losing local nuance


    This episode is a deep dive into the complexity โ€” and promise โ€” of coastal conservation. Itโ€™s for anyone interested in how nature-based solutions are designed, funded, and implemented at scale.
