Have you ever heard of World Oceans Day (WOD)?

The idea for WOD came from a meeting at the United Nations in 1992.

It's not a public holiday,

but people around the world now celebrate this special day on June 8 every year.

Oceans cover 70% of our planet.

They were once rich in fish and plants,

but now they are in serious trouble.

Garbage, oil spills, and overfishing

have made the number of ocean fish and plants much lower than before.

If we don't beat the clock and fix the problem, a lot of sea life will be gone soon.

To save the world's oceans, people celebrate WOD.

On this special day,

they hold movie festivals to teach the public about the beauty of the oceans.

They also clean up the beaches in their areas.

By celebrating WOD,

people not only learn a lot about oceans but also start to make them cleaner.

After all, we only have one Earth, don't we?
