12、用繩索拖到大船邊，用有刃的長(zhǎng)槍割取油脂，并把尸體拋棄。由于鯨油是貴重的工業(yè)原料，歷史上歐洲和美洲一些國(guó)家的捕鯨活動(dòng)長(zhǎng)盛不衰。自20世紀(jì)中葉起，由于過(guò)度獵捕導(dǎo)致資源衰退以及國(guó)際上對(duì)捕鯨的限制，捕鯨業(yè)已趨衰落?，F(xiàn)代捕鯨業(yè):挪威人福伊恩發(fā)明了一種捕鯨炮，用來(lái)發(fā)射內(nèi)充炸藥的標(biāo)槍。后來(lái)又使用了動(dòng)力船，與捕鯨炮相得益彰，這些方法使用至今幾乎沒有什么變化。人類和虎鯨聯(lián)合來(lái)獵殺我，真是太殘酷了！Itssocruelthathumanscooperatewiththekillerwhalestokillme!Ifyouwerethebaleenwhale,whatwouldbeyourlastthinking?
