World Ocean’s Day: Why the ocean is important

World Oceans Day is celebrated each year in June (usually on June 8). The United Nations hosts this event to raise awareness about the ocean and its importance to our planet.

Why is the ocean important?

We live on a blue planet: The ocean covers 70% of Earth’s surface.

Life began in the ocean over 3.5 billion years ago. The ocean is home to fascinating lifeforms, living in habitats as varied as coral reefs, the frigid waters of the Southern Ocean, and even deep, dark marine trenches. Scientists estimate that 90% of marine species are yet to be discovered!

The ocean supplies oxygen for us to breathe. It stores carbon and helps regulate the climate. It provides us with resources like food and medicine. It is where we play and have fun.
