The sea plays a fundamental role in regulating the climate of our planet; it produces over 50% of the oxygen, with a function comparable to that of tropical forests, and absorbs about a third of the excess of carbon dioxide released into the atmosphere by anthropogenic activities.
In recent years, however, fish stocks are missing, land and marine habitats are increasingly polluted (due to human activities), biodiversity is at risk and the oceans are becoming dangerously hot and acidic. The incautious and illegal fishingthat is disrupting the entire trophic network and the ever-increasing pollution are seriously endangering the vital functions of seas and oceans.
