Mini artificial islands mimic wetlands and help filter Missouri's lakes and ponds

Much of Missouri’s natural wetlands no longer exist. They were destroyed by agriculture and urban development which is a problem because wetlands filter contaminants and excess nutrients in water. Artificial floating wetlands are becoming a promising alternative that mimic the real thing on a smaller scale. Producer Ulaa Kuziez went to St. Charles County to check out how a new floating wetland installed by the Missouri Department of Conservation helps improve water quality.
