A coastal ecosystem is a dynamic environment where land meets the ocean. It includes various habitats such as beaches, estuaries, and mangroves. These areas are rich in biodiversity, supporting numerous species of plants and animals that thrive in both saltwater and freshwater conditions. Coastal ecosystems play a crucial role in protecting shorelines from erosion and providing essential resources for local communities. These ecosystems also serve as important nurseries for many marine species, including fish and crustaceans. They filter pollutants, improve water quality, and offer recreational opportunities. Overall, coastal ecosystems are vital for ecological balance and human well-being, highlighting the need for their conservation.
