Two studies of amphibians in Yosemite National Park in California confirm my conclusion. In 1915 there were seven species of amphibians in the park, and there were abundant numbers of each species. However, in 1992 there were only four species of amphibians observed in the park, and the numbers of each species were drastically reduced. The decline in Yosemite has been blamed on the introduction of trout into the park s waters, which began in 1920 . But the introduction of trout cannot be the real reason for the Yosemite decline because it does not explain the worldwide decline. Sample Essay In this argument, the writer of the letter concludes that global pollution of water and air has caused a decline in the number of amphibians worldwide. To support his or her conclusion, the writer cites the results of two studies, seventy-five years apart, that purportedly show that the number of amphibians in one park in California, Yosemite National Park, have drastically declined. Additionally, the writer casts aside a given reason for the decline, stating that the introduction of trout to the park does not explain the worldwide decline in the number of amphibians. This argument defies simple logic and suffers from several critical fallacies. |
