"The ocean is vast, covering more than two-thirds of the planet. Beneath its waves lies an amazing diversity of habitats, from coral reefs to polar seas. Each supports an astonishing array of life. And the ocean provides oxygen to the atmosphere and drives the world's climate-so all life on Earth depends on the ocean for survival."
