Marine Biodiversity
Marine biodiversity refers to the vast variety of life forms found in the oceans and seas, including plants, animals, and microorganisms. It encompasses diverse ecosystems such as coral reefs, deep-sea vents, and coastal habitats. This biodiversity is crucial for maintaining ecological balance, supporting fisheries, and providing resources for medicine and industry. Healthy marine biodiversity also helps regulate climate and supports livelihoods for millions of people worldwide.
