        Nature | Salmon: Running the Gauntlet - Humans and Salmon

        In this Nature video, learn how salmon, once an abundant and healthy species, felt the adverse effects of human interference from over-harvest, excess canning and habitat loss resulting in population depletion. As a result, people who depended upon salmon for their livelihood resorted to controlled experiments in salmon reproduction in the form of hatcheries or "salmon farms." Salmon populations were further harmed when people began to manipulate and dam the rivers, blocking passage to salmon spawning grounds.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
