Is it possible we will one day live on a planet with no fish in the oceans? This challenging documentary suggests that disconcerting future could be closer than we think, if important steps are not taken to prevent mass extinctions. The film examines the growing shortage of bluefin tuna, the overpopulation of jellyfish, and the global warning signs that lead scientists and fishermen alike to sound the alarm. 83 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital stereo; bonus shorts; featurette.
