Protecting our blue planet: Why world oceans day matters more than ever
From global awareness to local action, how data and collaboration can help safeguard our oceans
A few years ago, a group of volunteers on a European beach collected thousands of plastic items in just a few hours: bottles, fishing nets, and microplastics hidden in the sand. What started as a local clean-up quickly became part of a global movement. On Monday, 8 June, the world comes together once again to celebrate World Oceans Day, a moment to reflect on the vital role oceans play in our everyday lives and the urgent need to protect them.
Covering more than 70% of the Earth’s surface, oceans are essential to life on this planet. They help regulate the climate, absorb carbon dioxide, and provide food and livelihoods for billions of people worldwide. Despite their importance, oceans are facing increasing pressure from pollution, overfishing, and climate change. This year’s action theme, “Strong Marine Protected Areas for Our Blue Planet”, calls for stronger protection of marine ecosystems and reinforces global commitments to safeguard at least 30% of ocean areas by 2030.
Understanding what is happening beneath the waves relies not only on scientific expeditions, but also on data that is openly available. Across Europe, marine datasets help map biodiversity, monitor pollution, and analyse changing ocean conditions. Platforms such as the European Marine Observation and Data Network and Copernicus Marine Service make these insights accessible, supporting better decision-making across sectors like energy, fisheries, and climate policy. Curious to explore yourself? On the European Data Portal, search terms such as “marine biodiversity”, “sea surface temperature”, “coastal erosion”, or “marine litter” can reveal how data translates ocean challenges into tangible insights.
So, what role could you play in protecting our oceans? World Oceans Day is not just about awareness, it is about participation. Whether you explore a dataset, join a local clean-up, or simply rethink everyday choices, small actions collectively make a difference. Take a moment to dive deeper via the World Oceans Day website or challenge yourself to explore a dataset on the European Data Portal and see what patterns you can uncover.
