Wetlands are important for water purification because they act as natural filters. The vegetation and soil in wetlands help to trap and remove pollutants, excess nutrients, and sediments from the water passing through them. Wetlands also provide habitat for diverse plant and microbial communities that break down harmful substances, improving water quality. Additionally, wetlands can help to regulate water flow, reducing the risk of flooding and erosion, and thus contributing to overall watershed health.
