Today marks World Oceans Day, a worldwide movement to protect the marine ecosystem.

The oceans are under great environmental stresses due to growing world population, overfishing and pollution caused by consumerism. Plastics are now thought to make up about 90% of rubbish that clogs the ocean.

"In addition to events in dozens of countries, we invite everyone to take ocean conservation personally by making a commitment and then sharing a selfie for the sea," said World Oceans Day coordinator, Alyssa Isakower.

As part of World Oceans Day 2014, people are urged to join the Selfies for the Sea, with personal pledges for direct action and tagging it #WorldOceansDay.
