SATOUMI: People and Nature in Harmony

People living near Japan's Seto Inland Sea have worked with nature to create a special environment called "Satoumi". The projects they started revived an ecosystem that was once said to be dying. Chemicals from factories used to cause red tides that threatened marine life. Fishermen began using oysters and sea grass to clean the water. On this program, we look at how fishermen brought the Seto Inland Sea back to life and inspired people to develop "Satoumi" in other countries.
