Lake Yangushi is a natural, 4,000-acre freshwater body of water where the nationb s largest population of Steelhead trout live. Triad Corp., one of the countryb s biggest manufacturers of computer flash memory cards, built its factory about 300 meters from the southeastern shore of the lake in 2002. The local government gave Triad Corp. permission to pump its unpolluted leftover warm water into the lake. As a result, there is growing evidence that this runoff of warm water is encouraging the rampant growth of algae that are, in turn, severely reducing the population of Steelhead trout in the lake. Who or what would be considered the most important factors, according to each perspective? What actions might each perspective recommend be taken?
