Over five days, world leaders and scientists from more than 120 countries have gathered in Lisbon, Portugal, for the United Nations Oceans Conference.
Scientists say anywhere from 50 to 80 per cent of all life on the planet lives under the sea.
Oceans also generate about half of all oxygen in the atmosphere, and absorb a quarter of all carbon dioxide emissions.
And while net-zero emissions targets have been a big focus in tackling climate change, this U-N summit aims to establish a similar agreement to protect the ocean.
