A wetland ecosystem is a unique environment where water covers the soil for part or all of the year. These areas can include marshes, swamps, and bogs, and they are characterized by rich biodiversity. Wetlands provide essential habitats for many species, including birds, fish, and amphibians, and they play a crucial role in filtering pollutants from water. Wetlands also help in flood control by absorbing excess rainwater and slowly releasing it. They act as natural sponges, reducing the impact of storms and protecting nearby communities. Additionally, wetlands store carbon, which helps mitigate climate change, making them vital for both the environment and human well-being.
