World Oceans Day

World Ocean Day is an international day that takes place annually on 8 June. The concept was originally proposed in 1992 by Canada's International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit – UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil. "World Oceans Day" was officially recognised by the United Nations in 2008. The international day supports the implementation of worldwide Sustainable Development Goals (SDGs) and fosters public interest in the protection of the ocean and the sustainable management of its resources.
History.
1987–1992.
The Brundtland Commission (also known as the World Commission on Environment and Development) noted in the 1987 Brundtland Report that the ocean sector lacked a strong voice compared to other sectors.
At the first World Ocean Day in 1992, the objectives were to move the ocean from the sidelines to the center of the intergovernmental and NGO discussions and policy and to strengthen the voice of ocean and coastal constituencies worldwide.
2002–2008.
In the early years of coordinated efforts by The Ocean Project with World Ocean Network, events numbered in the dozens. During this time, www.WorldOceanDay.org launched, to help promote the event and generate more global involvement through the dissemination of educational and actionable resources, ideas, and tools free for everyone to use to celebrate World Ocean Day. In 2004, The Ocean Project and World Ocean Network launched the "Help Make a Difference for our Ocean Planet!" with both online and in person opportunities to sign a petition to the United Nations to officially recognize 8 June as World Ocean Day. In December 2008, the UN General Assembly passed a Declaration to officially recognise the Day.
