There are large peat-rich wetlands in Ireland. Environmentalists have always opposed coal mining in wetland areas. Their reason is that mining peat can disrupt the ecological balance of Irish wetlands, and its direct serious consequence is to pollute water sources. However, this One worry is untenable. According to relevant statistics in the past 50 years, there have been no reports of water pollution caused by coal mining. Which of the following, if true, is the best way to strengthen the argument? ? ["Coal mining in Ireland's wetlands has been 200 years old, and water pollution has never been caused by it.", 'In Ireland, the ecological environment of a coal-mined wetland is not substantially different from an unmined wetland.', 'The ecological environment of coal mining wetlands in Ireland is not substantially different from that before mining.', 'Ireland has sufficient technology and financial support to control pollution and protect ecology.']
