8th June- World Oceans Day

Oceans cover more than 70% of the Earth’s surface and constitute about 97% of water on Earth. It is a life support unit, supporting human sustenance and every other living organisms on the planet. It is home to many biodiversities of the world and also fulfils about 50-80% of the planet’s oxygen demand. Other than that, oceans absorb almost 30% of carbon dioxide produced by humans restraining global warming.

World Oceans Day is observed every year on June 8 to mark the significance of oceans and spread awareness about the negative impacts of human activities and exploitation of ocean water. The objective is to conserve and use ocean and other marine resourses sustainably.

Theme for 2021

‘The Ocean: Life and Livelihoods’ is the announced theme for the year. This year the United Nations has planned to highlight the grave dangers the oceans are exposed to due to human activities such as dumping plastic pollution, garbage disposal, oil leaks etc.. With 90% of big fish populations depleting, 50% damages to coral reefs, the purpose is to highlight the role of humans in preserving oceans and its biodiversities. The theme sheds light on the wonders of oceans and creating a balance and deep rooted understanding between oceans and human relations. Moreover, it is also meant to motivate sustainable use of marine resources with oceans being a huge part of our economy by proving trade routes and jobs to millions of people.


The first World Oceans Day was celebrated in the year 1992 at the Earth Summit of the United Nations Conference on Environment and Development (UNCED). However, it was only after 16 years that the United Nations General Assembly recognised the day officially as World Oceans Day and managed it to celebrate every year on 8th June.
