Oceanic biodiversity refers to the variety of life forms found in the world's oceans, including plants, animals, and microorganisms. This diversity is crucial for maintaining healthy ecosystems, as it supports food webs and contributes to the overall resilience of marine environments. Key habitats, such as coral reefs, mangroves, and deep-sea ecosystems, are home to countless species, many of which are still undiscovered. The oceans cover over 70% of the Earth's surface and are vital for regulating climate and providing oxygen. Marine biodiversity also plays a significant role in human life, offering resources like fish and pharmaceuticals. Protecting oceanic biodiversity is essential for sustaining these benefits and ensuring the health of our planet.
