Mangroves play a crucial role in coastal ecosystems due to their numerous benefits. They provide essential habitats for various marine and terrestrial species, including birds, fish, and invertebrates. Mangroves also act as a buffer, protecting coastlines from erosion and storm damage. They help improve water quality by filtering out pollutants and trapping sediments, which ultimately benefits coral reefs and seagrass beds. Additionally, mangroves serve as carbon sinks, absorbing and storing large amounts of carbon dioxide, thus helping mitigate climate change. Overall, the preservation of mangroves is vital for maintaining the health and resilience of coastal ecosystems.
