oceans, seas, rivers, lakes, and other water bodies cover 71% of the Earth’s surface. Marine biodiversity consists of various species of animals, be it the world’s biggest animal or the smallest.
The ocean is home to such innumerable species. According to a report presented by the United Nations’ Food and Agricultural Organisation, 40% of the world’s population lives within a 100 km radius of the coast. About 10-12% of people depend on the ocean for their livelihood. Oceans and seas work as a carbon sink, which means they have the ability to absorb excess carbon generated due to anthropogenic uses. They further play a major role in maintaining complex ecosystems.
