Humankind depends on oceans and seas. From the water you drink to the air that you breathe to the food you eat — all can come from or be transported by the ocean.
About half of the world’s population lives within the coastal zone, and ocean-based businesses contribute more than $500 billion to the world’s economy. Oceans cover around 70 per cent of the Earth’s surface.
They thus play an important role in the Earth’s climate and in global warming. One important function of the oceans is to transport heat from the tropics to higher latitudes. They respond very slowly to changes in the atmosphere. Beside heat, they take up large amounts of the carbon dioxide emitted by humankind.
They flow over nearly three-quarters of our planet, and hold 97% of the planet’s water. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it.
But despite their importance, oceans are facing unprecedented threats as a result of human activity. Every year, an estimated 8 million tonnes of plastic waste end up in the world’s oceans. At the same time, climate change is damaging coral reefs and other key ecosystems; overfishing is threatening the stability of fish stocks; nutrient pollution is contributing to the creation of dead zones; and nearly 80 per cent of the world’s wastewater is discharged without treatment.

The CLME+ Hub is an initiative of the Secretariat of the CLME+ Interim Coordination Mechanism (ICM), in collaboration with the CLME+ ICM Membership and (prospective) Partner Organizations. Development of the Hub has benefited from the financial support of the UNDP/GEF Project: “Catalysing Implementation of the Strategic Action Programme (SAP) for the Sustainable Management of shared Living Marine Resources in the Caribbean and North Brazil Shelf Large Marine Ecosystems” (CLME+ Project, 2015-2020). The CLME+ Project is executed by the United Nations Office for Project Services (UNOPS) in close collaboration with a large number of global, regional and national-level partners.
