The Ocean Conference 2025 opened today in Nice, France, marking a pivotal moment for global marine conservation. Delegates, scientists, and world leaders have gathered for the third United Nations Ocean Conference—running from June 9 to 13, 2025—to tackle urgent ocean threats such as plastic pollution, overfishing, and climate-driven warming.
🌊 Why the Ocean Conference 2025 Matters Now
World Oceans Day coincides with the conference, underscoring its importance. Currently, only 2.7–3% of the ocean is protected—well below the 30% target for 2030. This summit aims to shift from rhetoric to concrete action through the upcoming “Nice Ocean Action Plan”. Explore World Oceans Day 2025 initiatives here.
