World Oceans Day is celebrated on June 8, every year. The day is in place to create awareness among the people of the ocean's benefits. The ocean covers 70% of the planet and is our life source. It supports our sustenance and that of every other organism on earth.

The ocean produces at least 50% of the planet’s oxygen and is considered home to most of the earth’s biodiversity. Even though all its benefits, the ocean is now in need of support.
