Conserve and sustainably use the oceans, seas and marine resources for sustainable development.
The oceans and their temperature, life, chemical composition and current drive the global systems that make the earth a habitable place for humans. Our weather, rainfall, drinking water, climate, coastlines, much of our food and even the oxygen in the air we breathe are provided and regulated by the sea.
Marine pollution has reached alarming levels, with an average of 13,000 pieces of plastic debris per square kilometre of ocean.
The livelihoods of more than 3 million people depend on marine biodiversity. It is estimated that 30% of the fish population is overexploited.
The oceans absorb about 30% of the carbon dioxide generated by human activity. Since the start of the industrial revolution, there has been a 26% increase in the acidification of the seas and oceans.
Responsible, careful and effective management of this essential resource is a key factor in halting the massive degradation of our oceans, countering the effects of climate change and ensuring a sustainable future. Creating and enforcing laws to reduce overfishing, marine pollution and acidification of the seas and oceans is another key factor in achieving SDG 14.
