WHAT ABOUT THE OCEAN? A body of water or the planet’s life-support system?
The ocean is essential to life on Earth – regulating climate, producing oxygen, providing food and livelihoods, and supporting ecosystems. But it's in trouble. Today, it faces a triple crisis: overfishing, pollution, and climate change.In this episode, James and Daisy dive deep into the ocean’s role in climate stability. Why is ocean protection critical to solving the climate crisis? What were the key takeaways from the UN Ocean Conference? Can the ocean itself be part of the solution?SOME RECOMMENDATIONS: Ocean with David Attenborough – A stunning documentary highlighting both the beauty of the sea and the alarming ways human activity is depleting its resources.Ellen MacArthur Foundation – In 2005, Ellen MacArthur became the fastest person to sail solo around the world. Five years later, she founded the Ellen MacArthur Foundation to accelerate the transition to a circular economy. The Foundation warns that by 2050, oceans will contain more plastic than fish by weight.UN (2025) – The Nice Ocean Action Plan is a two-part framework that comprises a political declaration and over 800 voluntary commitments by governments, scientists, UN agencies, and civil society to protect the ocean. OTHER ADVOCATESAND RESOURCES:High Seas Treaty – Covers nearly two-thirds of the ocean that lies beyond national jurisdictions. Once ratified, this treaty will help close critical regulatory gaps and guide international cooperation on ocean protection. Law of the Sea Convention (1982) – An international treaty that established a legal framework for all marine and maritime activities, including navigation rights, territorial waters, and deep-sea mining.30 x 30 – A global campaign to protect 30% of the Earth's land and ocean by 2030. It's a key target of the Global Biodiversity Framework adopted at COP15 of the Convention on Biological Diversity in 2022.The Precautionary Principle – A decision-making approach that emphasizes taking preventative measures when there's a reasonable possibility of harm, even if scientific evidence is not fully conclusive.Dark Oxygen – At depths of 5km, where no sunlight can penetrate, oxygen appears to be produced by naturally occurring metallic “nodules” which split seawater - H2O - into hydrogen and oxygen.Blue Economy – Refers to the sustainable use of ocean resources for economic growth, improved livelihoods, and ocean ecosystem health. While widely used, the term lacks a universally agreed definition.Notpla – A biodegradable alternative to plastic made from seaweed.International Whaling Commission (IWC) – Established in 1946 as the global body responsible for management of whaling and conservation of whales.Marine Stewardship Council (MSC) – A non-profit organisation which aims to set standards for sustainable fishing.The White House (2025) - The Trump administration signed an executive order to accelerate deep-sea mining in both U.S. and international waters.Arnold Schwarzenegger (2025) – Speaking at the Austrian World Summit, he called for unified global action to combat pollution and safeguard the planet.SOME FACTS: UNESCO (2022) – The ocean covers about 71% of the Earth’s surface and holds over 97% of its water. Phytoplankton, a tiny marine plant that lives on the ocean’s surface, produces, through photosynthesis, roughly 50-80% of the oxygen we breathe.LSE (2023) – The ocean contributes to climate regulation by absorbing over a quarter of human-caused carbon dioxide emissions and around 90% of excess heat. Without the ocean, the average surface temperature, which is currently around 15°C, would instead be around 50°C.WEF (2020) – The annual gross marine product of the oceans totals $2.5 trillion per year - which would make it the eighth largest economy, in country terms.BBC (2025) – Bottom trawling or dredging is currently allowed in 90% of the UK's Marine Protected Areas. BBC (2025) – Over 2,000 scientists have recommended to governments that all deep sea exploration be paused whilst further research is carried out; just 0.001% of the seabed has been mapped.Thank you for listening!
