French Polynesia marine protected area is now the largest in the world, covering nearly 4.8 million square kilometers of ocean. This groundbreaking conservation effort was announced during the United Nations Ocean Conference and includes large no-take zones near the Society and Gambier Islands, along with expansive areas that restrict harmful activities like deep-sea mining and bottom trawling. The MPA recognizes traditional fishing rights while also preserving critical marine habitats.

Marine conservation leadership by French Polynesia demonstrates how small island states can make bold commitments to global biodiversity. Backed by IUCN standards and set to expand by another 500,000 km² by 2026, this initiative offers hope in a world where only 8.3% of the ocean is currently protected. In this episode, we explore what this means for ocean life, local communities, and global marine policy—and why the real work begins now with enforcement and support.

The problem with seaweed aquaculture is that it’s not always as ocean-friendly as it seems. While seaweed farming is often praised as a climate solution—able to sequester carbon, improve water quality, and support sustainable food systems—scientists are now warning that its rapid, unregulated expansion could be damaging vital marine ecosystems. In this episode of How to Protect the Ocean, we dive into how seaweed farms are being placed over seagrass meadows, disrupting fish nurseries, smothering biodiversity, and altering water chemistry in ways we’re only beginning to understand.

You’ll hear about the overlooked risks, from nutrient depletion and fertilizer runoff to coral reef shading and invasive species. We also explore solutions: better regulations, smarter zoning, and the importance of protecting seagrass habitats that store carbon and support marine life. Seaweed aquaculture can be part of the solution, but only if we act with caution and science in mind.

UNOC 2025 brought major headlines in ocean conservation—from billions pledged to protect biodiversity, to significant movement on the High Seas Treaty. In this episode, Andrew Lewin returns from the UN Ocean Conference in Nice, France, with a firsthand account of what was announced, what was promised, and what might actually happen.

Ocean finance was a hot topic this year. Governments, development banks, and private investors pledged record-breaking funding to tackle everything from plastic pollution to marine ecosystem restoration. But Andrew dives into why these billions still fall short—and which key ocean players stepped up (and who didn’t).

High Seas Treaty ratification took center stage, with 18 new countries signing on and momentum building fast. The episode also breaks down 30x30 targets, new marine protected areas—including a massive one in French Polynesia—and growing global support for a deep-sea mining moratorium. Andrew adds his personal observations and concerns about whether this enthusiasm will translate into real protection for the ocean.
