The ocean covers three quarters of the Earth's surface and represents 99 percent of the living space ont the planet volume.

The ocean contains nearly 200,000 identified species, but actual numbers may lie in the millions.

As much as 40 percent of the ocean is heavily affected by pollution, depleted fisheries, loss of coastal habitats and other human activities.

The ocean absorbs about 30 percent of carbon dioxide produced by humans, buffering the impacts of global warming.

More than 3 billion people depend on marine and coastal biodiversity for their livelihoods.

The market value of marine and coastal resources and industries is estimated at US$3 trillion per year, about 5 percent of global GDP.
