抱歉又來打擾大家了 這題是我現在最不懂題目到底想要我回答什麼的 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 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 (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.” 我一開始想到 1.本文不應該用單一國家公園去推全世界 2.兩份調查時間相差過久 時空背景有差 不應拿來討論 在看完範文後 範文內有提到從amphibians減少的原因去寫 如果是板上的大家會怎麼去寫這題 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.254.197.20

因為他有提到1915一個種類有很多隻 且有7種 但到1992

卻只剩下4種 且隻數變少 他把這歸因於trout是有點奇

怪 因為trout再怎麼會吃卵 也沒這麼利害會挑卵吃

作者一開始提到全世界物種減少是因為空氣或水污染

這個就有很大的問題,他沒有給其他資訊,如果是氣候

或者是可能天敵數量增加那也有可能會造成decline
