The ocean covers 70 percent of the Earth’s surface, is the planet’s largest biosphere, and is home to up to 80 percent of all life in the world. It generates 50 percent of the oxygen we need, absorbs 25 percent of all carbon dioxide emissions and captures 90 percent of the additional heat generated from those emissions. It is not just ‘the lungs of the planet’ but also its largest carbon sink – a vital buffer against the impacts of climate change.
