Coastal ecosystems are dynamic environments where land meets the ocean. They include areas like beaches, mangroves, estuaries, and coral reefs. These ecosystems are rich in biodiversity, providing habitats for various species of plants and animals. They play a crucial role in protecting coastlines from erosion and serve as nurseries for many marine species. These ecosystems also offer important resources for humans, such as fishing grounds and recreational areas. They help filter pollutants and improve water quality, making them vital for both ecological health and human well-being. Conservation of coastal ecosystems is essential to maintain their functions and the services they provide.
