Estuaries are unique coastal areas where freshwater from rivers meets and mixes with saltwater from the ocean. These dynamic environments are characterized by their rich biodiversity, providing habitats for various species of fish, birds, and other wildlife. The mixing of waters creates a nutrient-rich ecosystem that supports both aquatic and terrestrial life. In addition to their ecological importance, estuaries also serve as crucial buffers against storms and flooding, protecting inland areas. They are often sites for recreational activities and are vital for local economies, supporting fishing and tourism industries. Understanding and preserving estuaries is essential for maintaining healthy coastal ecosystems.
