PURPOSE: 8 June is World Oceans Day, the United Nations day for celebrating the role of the oceans in our everyday life and inspiring action to protect the ocean and sustainably use marine resources. On this occasion, we shed light on the wonder of the ocean and how it is our lifesource, supporting humanity and every other organism on Earth. Since its inception in 2008, the United Nations has celebrated World Oceans Day in recognition of the ocean’s importance as the sustainer of all life on earth. Topics we explore during the day include: ocean governance, the science-policy interface, oceans and climate change, sustainable ocean-based economies (blue economy), and marine protected areas, and etc. As the challenges to the ocean continue to grow, so does the need to understand them and to mobilize globally. Drawing in a global community through a series of in-person and virtual events and campaigns, the annual United Nations celebration has created an inclusive and dynamic platform, ignited a groundswell of awareness, and through multi stakeholder engagement, has yielded impactful action for the ocean and our blue planet.
FORUM: “Wonders; Sustaining what sustains us." World Oceans Day 2025. This year, we celebrate the ocean’s essential wonder from all of the wonders it consists of to the wonder it ignites, and call on decision-makers to not lose sight the ocean’s wonder when determining its fate. Wonder is the foundation of scientific knowledge, the allure behind exploration, the curiosity that drives innovation, and the seed of traditional wisdom. In the face of increasingly daunting challenges, the act of wondering serves to remind us that we are part of something bigger. It wakes us up to our inherent connection to the earth and to each other, expands our understanding of what is possible, empowers innovation and prioritizes decision-making for collective well-being. The ocean’s wonder is what draws us in and often drives our desire to protect it. Join the conversation with the hashtags: #WorldOceansDay, #8june, #OceanFirst.

WHY WE CELEBRATE THE DAY?
The Date of June 8th is a day for humanity to celebrate the ocean. In the interim, observation of Oceans Day had broadened and deepened. The need and scope for this was reflected in the broad range of concerns expressed in 2008 by the United Nations Secretary-General, including implementation of the UN Convention on the Law of the Sea, maritime space, international shipping, maritime security, marine science and technology, marine biological diversity, the marine environment and sustainable development, climate change and regional and international cooperation. The awareness and action spurred by observation of World Oceans Day would be crucial in all these areas. Looking at our Earth from space, it is obvious that we live on a water planet. Ocean covers over 70% of the Earth's surface and contains about 97% of the Earth's surface water. Life in the oceans can be found from the surface to the extreme environments at the bottom of the deepest submarine trench. It is not surprising that the oceans represent over 99% of the living space on Earth...we are indeed living on what is truly an ocean planet. Let’s celebrate the Oceans!
