Wetlands play a crucial role in the environment by providing various ecosystem services. They act as natural buffers against flooding by absorbing and storing excess water during heavy rainfall. Wetlands also help in purifying water by filtering out pollutants and trapping sediments, thereby improving water quality. Additionally, wetlands serve as habitats for a diverse range of plant and animal species, supporting biodiversity and providing breeding grounds for many aquatic and bird species. Overall, wetlands contribute significantly to maintaining ecological balance and supporting various environmental functions.
