World Ocean Day 2025 celebrates the theme Wonder: Sustaining What Sustains Us, highlighting the ocean's vital role in supporting all life on Earth. Covering 70 percent of our planet's surface, oceans generate much of Earth's oxygen, absorb CO2, and provide vast quantities of food. Yet these magnificent ecosystems face mounting threats from pollution, over-exploitation, and climate change. Join the global movement to protect what sustains us all - because a healthy ocean means a healthy planet for future generations.
