Explore the oceans in this free online course and learn how marine life is crucial to ecosystems and our survival. Water covers more than two thirds of the Earth's surface and marine organisms produce more than half of the oxygen we breathe while helping to regulate the planet's climate, which explains why we refer to the oceans as the ‘planet's heartbeat’. This marine biology course explains how oceans also provide us with food, jobs and entertainment. We go beneath the waves to show you how marine life interacts to create sustainable ecosystems.
