World Oceans Day: Life and Livelihoods | World Meteorological Organization

The ocean covers over 70% of the planet and produces at least 50% of the planet’s oxygen. It drives our weather and climate, is home to most of earth’s biodiversity and is the main source of protein for more than a billion people around the world. The “blue economy,” which is estimated at US$ 3-6 trillion/year, accounts for more than three quarters of world trade and providing livelihoods for over 6 billion people.
