12、用绳索拖到大船边，用有刃的长枪割取油脂，并把尸体抛弃。由于鲸油是贵重的工业原料，历史上欧洲和美洲一些国家的捕鲸活动长盛不衰。自20世纪中叶起，由于过度猎捕导致资源衰退以及国际上对捕鲸的限制，捕鲸业已趋衰落。现代捕鲸业:挪威人福伊恩发明了一种捕鲸炮，用来发射内充炸药的标枪。后来又使用了动力船，与捕鲸炮相得益彰，这些方法使用至今几乎没有什么变化。人类和虎鲸联合来猎杀我，真是太残酷了！Itssocruelthathumanscooperatewiththekillerwhalestokillme!Ifyouwerethebaleenwhale,whatwouldbeyourlastthinking?
