The 2030 Agenda commits to protecting life underwater in all its forms, which is threatened by pollution, plastics and overfishing and illegal fishing.  

Specifically, it aims to: reduce pollution; create marine reserves and protected areas where fishing is prohibited; and explore ways to reduce the amount of plastic in the sea, much of which is waste from fishing and industry.  

The oceans play a fundamental role in the well-being of humanity and the social and economic development of the planet. The oceans and seas are very important to the planet, covering more than two-thirds of its surface. They produce half the oxygen we breathe and absorb 30% of carbon dioxide emissions, slowing the effect of climate change, although this capacity is now decreasing due to acidification (the presence of chemicals that kill fish and the marine ecosystem).
