A short theatrical featurette dealing with pollution, made by the Department of Interior's Fish and Wildlife Bureau. Concerning the problem of polluted estuaries and stressing the importance of our coastal waters, the films takes a look at the results of social negligence - waters ruined by human and industrial waste, nature's delicate balance thrown away. Life that once flourished in America's rivers has disappeared, to the growing alarm of the Fish and Wildlife Bureau, but the film also outlines what can be done to preserve our invaluable estuarine and the life dependent upon them.
