Significance of Oceans

Oceans are not just massive bodies of saltwater. They are life-givers. Here are a few reasons why oceans are significant:

• Produce over 50% of the oxygen we breathe

• Absorb about 30% of carbon dioxide emissions, helping to combat climate change

• Support over 3 billion people who rely on marine resources for their livelihoods

• Regulate Earth’s temperature and weather patterns

• Provide food—fish and seafood are major global food sources

• Home to millions of species, many yet to be discovered

Without healthy oceans, our survival is at risk. The oceans also offer solutions to problems like food security, renewable energy, and medicine. Their importance goes far beyond what we see on the surface.
