Yellowstone Fish Kill Points to Huge Toll of Human Activity on Rivers

The guardian has an excellent article on new research regarding last season’s Yellowstone fish kill, and the implications it has on the toll of human activity on rivers. From the article:

“In effect, these myriad human activities contribute to the weakening of the “immune systems” of rivers like the Yellowstone, making aquatic organisms more vulnerable to stresses like fish-killing parasites. The paper said these pernicious changes are being experienced in waterways across western North America and in other mountain river systems, including some found in Europe, the Andes, the Himalayas, and the high country of New Zealand.”
