The End of the Line (2009)

In the last two decades, the technology of commercial fishing has begun to overwhelm the world's oceans. With nets the size of canyons, video sonar, and electric bottom-trawlers that literally scour the ocean floor, fishermen are no longer simply ''fishing.'' They're subjecting threatened species to the equivalent of carpet bombing, and this passionate ecological documentary, The End of the Line, spells out the problem in clear, urgent, prosaic terms, from the threatened extinction of the regal and coveted bluefin tuna to the 
ongoing disaster of farm fishing, in which 40 percent of the world's undersea harvest is used merely to feed farmed fish. B+
