World Ocean Day 8th of June 2025!

World Ocean Day is here!!! 

a day to honour, celebrate, and protect the incredible blue planet we call home.
This year’s theme, ‘Sustaining What Sustains Us’, is a beautiful reminder that the ocean gives us life.

Now it’s time for us to give back.

The ocean covers over 71% of our planet, producing more than half of the world’s oxygen and absorbing vast amounts of carbon dioxide. It regulates our climate, provides food, supports millions of livelihoods, and offers countless moments of peace, adventure, and inspiration to those of us lucky enough to experience it. Whether you’re a diver, snorkeller, beach walker, or just someone who loves the sound of waves — the ocean sustains us all.

Here on Koh Tao, Thailand, we see first-hand how the ocean sustains our island community and diving industry.
At Big Blue Conservation, we believe every day should be World Ocean Day — but today is an extra-special opportunity to raise awareness and inspire change.

How To Get Involved This World Ocean Day

Wherever you are in the world, we encourage you to take a moment today to appreciate our ocean and consider how you can help protect it. Even the smallest actions make waves!

Join a Beach or Dive Clean-Up:
If you’re on Koh Tao, we’re hosting a special World Ocean Day Dive Against Debris and beach clean-up right here at Big Blue Diving!

Can’t make it to the island? No worries — grab a bag and hit your local beach, riverbank, or dive site. Every piece of rubbish you remove makes a difference.

Pause and Appreciate the Ocean:
Spend a few minutes today by the shore, underwater, or simply looking out at the horizon.
Reflect on how the ocean sustains you personally — whether through your work, your hobbies, your travels, or your mental well-being.

Make a Small Eco-Switch:
Switch to reef-safe sunscreen.
Say no to single-use plastics.
Support sustainable seafood choices.
Each small decision adds up when we all work together.

Together, We Can Keep Our Oceans Alive

At Big Blue Conservation, every day is a chance to protect what we love.
From up and coming coral restoration projects to marine debris surveys and eco-education workshops, we’re committed to sustaining the marine ecosystems that sustain us.

Happy World Ocean Day to everyone from our Big Blue family!!!


Let’s dive in, clean up, speak out, and protect our oceans — for ourselves and for future generations!
