Why is the Ocean so Important?

The Ocean is the heart of the planet. Water covers more than two-thirds of the Earth’s surface. Sea plants, like Posidonia, produce 70% of the oxygen we breathe (1), and the deep waters are home to wildlife and some of the biggest creatures on earth. It provides us with food, jobs, life, entertainment, and sailing! Without it, we cannot survive. Why should we care so much about the creatures that live in the ocean? Does it matter if a species disappear? What does that mean for us?
