French Polynesia creates the world’s largest marine protected area
French Polynesia’s Tainui Atea marine protected area, announced at the 2025 UN Ocean Conference in Nice, now spans over 4.5 million square kilometers, making it the largest marine protected area on Earth. The designation bans bottom trawling and deep-sea mining while preserving traditional artisanal fishing, protecting waters home to 21 shark species, 176 coral species, and over 1,000 fish species. Critically, 92 percent of French Polynesians surveyed support the protections, grounding this effort in genuine community ownership rather than top-down policy. The move raises global marine protection coverage to 9.85 percent, advancing the international 30×30 conservation goal.
