The oceans of the world cover approximately 70% of the earths surface. Approximately 4/5 of all animals and plants live in th ocean. Because we usually don't spend a lot of time out in the ocean we can forget how many amazing animals and plants use the ocean as their homes.

The ocean plays a vital role in our lives eg; transport fishing minerals energy communication Why is it important to keep the ocean clean and healthy? Humans, plants and animals depend on the oceans for their survival. The oceans absorb the carbon dioxide that we generate- carbon dioxide is a part of the greenhouse issue.

The ocean is home for the smallest plants and animals to the giant whales. Some animals drift on the currents, some swim and some live in the deep dark water near the bottom. Most plants that live in the ocean can only live where there is enough light. So the deeper you go in the ocean the less plants there are.
