据美刊报导:如果各国政府不从现在开始,投入更多的资金治理水资源,到2025年用不上洁净水的人口将增加到25亿。估计21世纪水对人类的重要性同石油在20世纪对人类的重要性一样,它将成为一种决定国家富裕程度的珍贵商品。有关专家指出,水业管理孕育着全球最大的商机,全球每年需向人们供应生活和生产用水达4000亿美元以上,目前有10亿人口很难用上洁净水,30亿人口缺乏污水处理设备。 According to the American Journal, if governments do not start investing more funds to control water resources from now on, the population that does not use clean water will increase to 2.5 billion by 2025. Estimating the importance of water for humankind in the 21st century, like the oil’s importance to humankind in the twentieth century, will become a precious commodity that will determine the country’s affluence. Experts pointed out that water management has given birth to the world’s largest business opportunity. Every year, the world needs to supply more than 400 billion U.S. dollars of domestic water and water for production. Currently, 1 billion people have difficulty using clean water and 3 billion people lack sewage treatment facilities.
