"Students should bring a certain skepticism to whatever they study.
They should question what they are taught instead of accepting
it passively."

The following is a letter to the editor of an environmental magazine. "The
decline in the numbers of amphibians worldwide clearly indicates the global
pollution of water and air. Two studies of amphibians in YosemiteNational
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 (trout are known to eat amphibian eggs). But the
introduction of trout cannot be the real reason for the Yosemite decline
because it does not explain the worldwide decline."
