Estuaries are important ecosystems that serve as a transition zone between rivers and the sea. They provide valuable habitats for various species of fish, birds, and other wildlife. Additionally, estuaries play a crucial role in filtering pollutants from water, protecting shorelines from erosion, and supporting commercial fisheries. They also serve as breeding grounds for many marine species and help regulate water flow and nutrient cycling. Overall, estuaries are vital for maintaining biodiversity and supporting the health of coastal ecosystems.
