Since 2009, 8 June has been celebrated by the United Nations around the world as the Day of the Sea to draw attention to the value of and threats to the world's oceans.

The oceans are still the least protected areas on earth. The United Nations has agreed to establish protected areas for at least 10 per cent of the oceans by 2020. Oceans contain 97 per cent of the world's water resources. They are rich in biodiversity, provide raw materials, food and active ingredients for medicines. They hold energy reserves, serve as transport routes and provide valuable recreational space.
