Oceans: they cover 71 percent of the Earth's surface | Photo: Michael Fraley/Creative Commons

The world's oceans were kept out of the 2015 Paris Climate Change Conference (COP21-CMP11), an event promoted by the United Nations (UN).

Despite the smiles, hugs, and the applauses, the so-called Paris Climate Change Agreement is not good news for marine life. Our oceans cover 71 percent of the Earth's surface, but they were only mentioned once in the final document.

The 32-page concordat refers the word "oceans" in the Annex, to say that all parties note "the importance of ensuring the integrity of all ecosystems, including oceans, and the protection of biodiversity, recognized by some cultures as Mother Earth."

Our oceans need practical proactivity. Marine life is in danger. When will we ban the microbeads? When will humans stop throwing plastic bags into the seas? When will civilized nations treat sewage? When will we protect corals?

The relation between Paris Climate Change Agreement and the oceans is strictly indirect. The seas of the world are the barometer of life in our planet, and the real-life connection between global warming and the world's oceans is too evident to obscured.

The COP21-CMP11 failed to address the problems of the oceans and, therefore, failed to deliver the answer we all needed from politicians and technocrats. We have the responsibility to do more.
