More human interference with nature, but this time maybe things aren't as bad as one would think...
"The heavily dammed Columbia and its largest tributary the Snake River in the northwestern United States serve as a breeding ground to millions of salmon, including endangered chinook and steelhead species, which have been dwindling steadily for years." (discovery news)
However, the damning appears to have no negative effect on any of the millions of salmon that reside in it's waters.
"Whether or not the eight dams along the rivers contribute to the decline has been a source of bitter controversy for decades. Conservation groups, the commercial and sport fishing industries and local Native American tribes have long blamed the fishes' plight on the dams."
