June 8 was designated as World Oceans Day by the United Nations in 2008.
Oceans cover most of our planet. They provide much of the oxygen we need to survive, regulate weather and temperature, and are home to countless plants and animals. Yet, the oceans face continued threats from pollution, overfishing, and warming temperatures.
The pictures below remind us of the ocean’s beauty and how important it is to protect and preserve this system.
