Studying marine biodiversity is significant because oceans are home to a vast array of species that contribute to ecological balance and human economies. Healthy marine ecosystems provide essential services, such as carbon sequestration, coastal protection, and fisheries. Understanding marine biodiversity also helps scientists monitor the health of ocean environments, which are increasingly threatened by pollution, overfishing, and climate change. Furthermore, conserving marine biodiversity is crucial for ensuring food security and maintaining cultural values tied to marine resources.
