World Oceans Day reminds every one of the major role the oceans have in everyday life. They are the lungs of our Planet and a major source of food and medicine and a critical part of the biosphere.

The purpose of the Day is to inform the public of the impact of human actions on the ocean, develop a worldwide movement of citizens for the ocean, and mobilize and unite the world’s population on a project for the sustainable management of the world's oceans.

World Environment Day, marked annually on 5 June, was established by the United Nations General Assembly in 1972. Over the past five decades, the Day has grown to be one of the largest global platforms for environmental outreach. Tens of millions of people participate online and through in-person activities, events and actions around the world.
