Nature - Season 29 - Eps 13: Salmon: Running the Gauntlet
This film investigates the collapse of Pacific salmon populations and the desperate efforts to save them: Our once great runs of salmon are now conceived in laboratories, raised in tanks, driven in trucks, and farmed in pens. In its exposure of a wildly creative, hopelessly complex, and stunningly expensive approach to managing salmon, the film reveals one of the most ambitious plans ever conceived for taking the reins of the planet.
