“引狼入室”的意思本来是指将灾祸带入自己家中,是应杜绝的行为。然而现在,随着自然生态环境的恶化,全球有不少国家正在实施“引狼入室”行动计划。在美国洛基山脉北部,时隔多年,又传来阵阵狼嚎。早在20世纪90年代,美国内务部野生动物保护局为恢复已在此灭绝的狼群,不惜耗费巨资从加拿大“引狼入室”。 “Lead the wolf into the room,” the meaning of the original refers to the disaster into their own homes, should be put an end to the behavior. However, nowadays, with the deterioration of the natural environment, many countries in the world are implementing the plan of action. In the north of the Rocky Mountains in the United States, after a lapse of years, another wave of howl was heard. As early as the 1990s, the U.S. Department of the Interior Wildlife Protection Agency spent huge sums of money to recover from wolves that were already extinct here.
