Answer:
The ocean is important because it is a very large part of our planet. In fact, it covers 70% of Earth’s surface. The ocean is a home and food source for countless fish, mammals, plants, birds, and more.
The ocean plays an important role in whatever happens in our environment on Earth. Even if you live on land – like humans do – you wouldn’t survive without the ocean!
One example: without the ocean, Earth would be much hotter than it is right now. That’s because the ocean absorbs heat from the Sun and spreads it more evenly around our planet.
