Since 2009, people around the world have celebrated World Oceans Day. The United Nations General Assembly took the concept, first proposed in 1992 and made it official on 5 December 2008. Since then, the event has grown and spread as the realization of the ocean’s importance to humanity has increased.

Did you know:

  • Oceans cover three quarters of the Earth’s surface, contain 97 percent of the Earth’s water, and represent 99 percent of the living space on the planet by volume. To date only a little over 1 percent of the ocean is protected.
  • An estimated 50-80 percent of all life on earth is found under the ocean surface and the oceans contain 99 percent of the living space on the planet. Less than 10 percent of that space has been explored by humans.
  • Tiny marine plants called phytoplankton release half of all oxygen in the atmosphere through photosynthesis.
  • The oceans account for 96 percent of all the water on the surface of the Earth, the remainder being freshwater, in the form of rivers, lakes and ice.
  • Over three billion people depend on marine and coastal biodiversity for their livelihoods.
  • Globally, the market value of marine and coastal resources and industries is estimated at $3 trillion per year.
  • Oceans contain nearly 200,000 identified species, but actual numbers may lie in the millions.
  • Oceans serve as the world’s largest source of protein, with more than 2.6 billion people depending on the oceans as their primary source of protein.
  • As much as 40 percent of the world oceans are heavily affected by human activities, including pollution, depleted fisheries, and loss of coastal habitats.
