More than half the wetlands in the U.S. have been drained or destroyed, while traditional farming methods have allowed topsoil to erode into streams and lakes. What is being done to heal the habitats crucial to the well-being of planet Earth? In this program, experts from the Olentangy River Wetland Research Center, the U.S. Army Corps of Engineers, major corporations, and government agencies discuss case studies of environmental remediation. These scenarios include Delaware’s Eagle Run project, in which a junkyard was transformed into a freshwater tidal marsh; Louisiana’s Sherburne Wildlife Management Area project; and the ongoing rehabilitation of Florida’s Everglades. In addition, the methods and benefits of "no-till farming" are examined. (24 minutes)
