Taiwan's pork industry, for example, boomed when Japan opened up its market to pork imports in 1977. By 1994, Taiwan had already been the biggest exporter of pork to Japan for many years, but the 10 or 20 thousand small scale pig farmers (raising from a few dozen to a few hundred head) could not afford antipollution equipment nor could they lower costs.
以養豬業為例，日本在一九七七年開放豬肉進口後，台灣養豬業一路竄升，民國八十三年，台灣已維持豬肉出口日本之冠多年。但為數多達一、兩萬的養豬戶，幾十、幾百頭的規模，不僅投資污染防治設備困難，也無法降低經營成本。
