World Oceans Day 2025

Mark your calendars for June 8, 2025, as the world comes together to celebrate World Ocean Day. This annual event serves as a reminder of the critical importance of protecting our oceans and marine life.

Why do we need World Oceans Day?

Our oceans cover 70% of the planet’s surface and play a vital role in sustaining life. From providing oxygen for every second breath we take to feeding billions of people and hosting 80% of the world’s biodiversity, the ocean is essential to our existence.However, our oceans are facing unprecedented threats. Pollution, overfishing, bycatch, and climate change are putting marine biodiversity at risk.

Taking action on World Ocean Day

World Ocean Day is not just a day of awareness but a call to action. It’s an opportunity for individuals and communities worldwide to unite in efforts to protect and preserve our oceans for future generations.At the MSC, we know that sustainable fishing is critical to ensuring that the ocean has healthy fish populations, that marine ecosystems are protected, and that people around the world have access to healthy seafood for generations to come.

This World Ocean Day, we’re celebrating the role that MSC-certified sustainable fisheries play in protecting the ocean and showing how sustainable fishing means so much more than you might think.

Exploring the five oceans

While the Earth has one big ocean with many features, humans understand there to be five oceans or oceanic divisions:

• The Pacific Ocean: the largest and deepest ocean between Asia and the Americas
• The Atlantic Ocean: Second largest ocean between Europe, Africa and the Americas
• The Indian Ocean: Third largest ocean, between Asia, Africa and Australia
• The Arctic Ocean: the smallest, shallowest and coldest located toward the North Pole
• The Southern Ocean (or the Antarctic Ocean): The southernmost waters of the world ocean around Antarctica toward the South Pole
