Scores of feminized male frogs...rivers of blood and sewage...pesticide-filled tap water...gender-switching fish...a clandestine group controlling one of the elements...It could be a modernized list of biblical plagues, but these are just a sampling of facts exposed in Irena Salina's disturbing documentary, FLOW. The film is an in-depth accounting of our most precious and diminishing resource. Water has become a coveted commodity, and a $400 billion global industry-the third largest behind electricity and oil. Corporate water privatization wreaks havoc on poor communities around the world, while loosening and/or nonexistent environmental restrictions have had a disastrous result on the entire food chain, putting everyone and everything at risk. Salina's broad approach to the international water crisis tends to overreach, yet her thoroughly researched, deeply personal appeal is a call to action that cannot be denied. While FLOW's news is dire, one of the film's great strengths lies in Salina's ability to find hope and inspiration in the most unexpected places.
