Description: . Filmed in the east coast marshes of the United States, this film is a study of the ecological system of estuaries. Documents the work of researchers from the University of Georgia in measuring the productivity of marsh grasses. Examines the effect of pollutants and reclamation projects on the fragile salt-marsh ecosystem, and points out the need to conserve the salt marshes as an irreplaceable natural resource., Analyzes the complex ecosystem of the salt marsh, emphasizing the urgent need to preserve the salt marshes from modern development projects which would drain and thus destroy the salt marshes as valuable ecosystems. Documents the value of the biological communities that exist between sea and land and explores the many food chains which are dependent upon the survival of the salt marshes.
