7644FINITE OCEANSFINITE OCEANS1995color51 minvhs Dr. Roger Payne presents a view of oceans as finite bodies of water--a view diametrically opposed to our preconceptions about the "limitless" seas into which we discard vast quantities of toxic, industrial wastes (immortal synthetic poisons). Learn how small concentrations of pollutants such as DDT, PCBs and pesticides threaten ecosystems at all levels. While it's early to see the effects of chemicals we produce on the oceans, we can clearly see their effects on the larges bodies of fresh water such as the Great Lakes. Their fragility sounds a warning about problems that threaten not only wildlife but human lives as well.
