Our planet is mainly covered with 139 million square miles or 360 million square kilometers of water.
Interestingly, 80% of life on Earth is found on our seas, rivers, lakes and oceans. Other than serving as habitat of aquatic organisms, the marine environment gives us more benefits, as follows:
- Most of the earth’s oxygen is a product of photosynthesis in ocean organisms.
- The fresh water on the earth’s surface comes from the oceans.
- The ocean moderates the earth’s climate and affects the weather.
