Yang Ping-shih cites the example of National Taiwan University's experimental fields. Not long ago, you could still catch 40 or 50 fireflies in one night. Later the school made experiments with pesticides there. "Now, even if you turn the field upside down," he says, "you won't find half a firefly."
楊平世就舉台大舟山路上的實驗農田為例，不過幾年前，一個晚上還可抓上四、五十隻螢火蟲，後來學校在稻田裡做農藥實驗，「今天將水稻田翻遍，也找不到半只螢火蟲」，他說。
