Description: Shows man's interference with the balance of nature at Pyramid Lake, Nevada, and the resulting environmental destruction. Explains that dams have diverted the natural flow of a river from Lake Tahoe, the major source of water for Pyramid Lake, causing it to dry up gradually. Indicates that this is the natural habitat of white pelicans and cui-cui, a desert fish found only in this region, and that their existence is threatened. Illustrates how sonic booms frighten the pelicans away from their nests, letting gulls steal eggs, and how fresh water spawning cui-cui die in an overly shallow river.
