Protecting our blue planet: Why world oceans day matters more than
ever
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
[https://worldoceanday.org/], 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
[https://data.europa.eu/en], search terms such as “marine
biodiversity
[https://data.europa.eu/data/combined?query=marine%20biodiversity&locale=en]”,
“sea surface temperature
[https://data.europa.eu/data/combined?query=sea+surface+temperature&locale=en&page=1]”,
“coastal erosion
[https://data.europa.eu/data/combined?query=coastal+erosion&locale=en&page=1]”,
or “marine litter
[https://data.europa.eu/data/combined?query=marine+litter&locale=en&page=1]”
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
[https://unworldoceansday.org/] or challenge yourself to explore a
dataset on the European Data Portal [https://data.europa.eu/en] and
see what patterns you can uncover.
