Wetlands play an essential role in regulating water quality by acting as natural filters. They trap sediments, absorb pollutants, and break down harmful substances, thus improving water clarity and quality. Wetlands also provide habitats for diverse wildlife and contribute to groundwater recharge. Additionally, they can buffer against flood events, mitigating the impact of excess water runoff. Protecting and restoring wetlands is crucial for maintaining ecosystem health and ensuring clean water supplies.
