The oceans cover about two-thirds of the surface of the Earth and are the very foundations of life. They generate most of the oxygen we breathe, absorb a large share of carbon dioxide emissions, provide food and nutrients and regulate climate. They are important economically for countries that rely on tourism, fishing and other marine resources for income and serve as the backbone of international trade.

Unfortunately, human pressures including marine pollution, are taking a significant toll on the world’s oceans and seas.
