The Ocean: Earth’s Vast and Vital Blue Heart

Introduction Covering more than 70% of the Earth’s surface, the ocean is the planet’s largest ecosystem, a vital life support system, and a source of wonder and mystery. It is home to an astonishing diversity of life forms, from microscopic plankton to the largest animal on Earth—the blue whale. The ocean not only regulates climate, provides food, and supports biodiversity, but it also plays an essential role in global economic and cultural systems. Despite its vastness, the ocean is under severe threat from human activity, including pollution, overfishing, and climate change.
