The third UN Ocean Conference was recently held in Nice, France, bringing together a diverse and impassioned group of stakeholders from around the globe. Thousands of delegates, including heads of state, scientists, environmental advocates, Indigenous leaders, and youth activists, convened to address the escalating crisis facing the world’s oceans. Under the theme “Ocean Wonders”, the conference highlighted both the awe-inspiring beauty of marine ecosystems and the urgent need to protect them from mounting threats.
A key focus of the event was the ambitious goal of expanding marine protected areas. Currently, only about 2.7% of the world’s oceans are under full protection. Leaders at the conference called for a significant increase—to safeguard at least 30% of the ocean by 2030, in line with the global “30×30” conservation target. Scientists emphasized that this level of protection is not just aspirational but essential for maintaining biodiversity, ensuring food security, and mitigating climate change.
At the heart of the discussions was the ratification and implementation of the High Seas Treaty—an international agreement adopted in 2023 but still awaiting formal approval by many countries. The treaty would enable the creation of large-scale marine preserves in international waters, which make up two-thirds of the world’s ocean surface and currently lack comprehensive governance. Delegates stressed that without legal frameworks like this treaty, efforts to halt overfishing, protect endangered species, and combat deep-sea mining will remain fragmented and insufficient.
Throughout the conference, there was a palpable sense of urgency. The degradation of ocean ecosystems has accelerated in recent years due to warming waters, acidification, pollution, and unsustainable industrial activities. Fish populations are declining, coral reefs are bleaching, and the livelihoods of millions who depend on the sea are at risk. Yet, despite the dire warnings, the conference also carried a sense of cautious optimism.
While the UN Ocean Conference 2025 did not provide immediate solutions to every challenge facing our seas, it served as a critical turning point. More than symbolic, the commitments made—ranging from funding for marine science and coastal restoration to pledges of zero tolerance for illegal fishing—signaled a shift from rhetoric to responsibility. The real test now lies in implementation.
The time for symbolic gestures has passed. What is needed going forward is unwavering political will, transparent mechanisms of accountability, and deep collaboration that transcends borders, industries, and communities. If the promises made in Nice are honored and enforced, this conference could be remembered as a landmark moment in humanity’s evolving relationship with the ocean—a moment when the world finally began to act on the scale that the crisis demands.
