The theme for World Oceans Day 2019 is 'Gender and the Ocean', which urges to promote gender equality in ocean-related activities like marine scientific research, fisheries, labour at sea among others.
The United Nations and international communities observe World Oceans Day on June 8 every year. While 97% of the earth’s water is in the oceans, it also provides us with oxygen and takes in most of the carbon dioxide. The theme for World Oceans Day 2019 is 'Gender and the Ocean', which urges to promote gender equality in ocean-related activities like marine scientific research, fisheries, labour at sea among others.
The oceans continue to amaze us with its beauty and resources every now and then. While the water is mysterious yet beautiful, a lot of it still stays unexplored. Here are a few facts about oceans that will amaze you and urge you to save oceans:

8. In 2002, scientists discovered an area in a remote part of the Pacific Ocean, partway between Baja California and Hawaii, where coastal great white sharks migrate in the winter. The scientists named the spot ‘White Shark Café’.
9. Only three people have managed to make it to the Mariana Trench, because of the extreme conditions there. One of those people is director James Cameron.
10. 90% of all the volcanic activity on the planet happens in the ocean, with South Pacific having the largest known concentration of active volcanoes.
