Barbara Ettinger's new film, A Sea Change, looks at the effects of ocean acidification on the world's waters. As the make-up of the oceans are altered through pollution and global climate change, could we be looking at the possibility of a world without fish? Circling the world, from the Arctic Circle to aquariums and swimming pools, A Sea Change doesn't just dwell on impending doom, but actively seeks out ways we could turn back the tide. It premieres on Sept 13th in New York City.
