Some 70 percent of Earth’s surface is covered by water, most of that being oceans. Oceans are the source of the world’s rain and therefore its freshwater. Oceans generate much of Earth’s oxygen supply, absorb CO2, provide a huge quantity of food, are the highways of much international trade, and are loved by many for the natural beauty and recreational opportunities they provide.
But the fact is, the world’s oceans are too often polluted and over-exploited, and coral reefs and other marine habitats are sometimes endangered as surely are certain species of sea creatures.
World Oceans Day aims to remind us all of the importance of our world’s oceans, work toward diminishing threats to oceanic health, and mobilise an international movement for sustainable use of our oceans’ natural resources.
