生命是脆弱的,恢复它要比扼杀它艰难得多。科学家找到了湖水死亡元凶磷盐的主要来源。除了工业污染源以外,另一个主要来源竟是人们日常生活中每天都在制造的东西——生活污水。从阿尔卑斯罗讷大冰川发源的罗讷河沿着横贯瑞士南部的瓦莱大山谷一路奔流而下,汇入了一个方圆八千平方公里的大湖。在湖里沉淀下一路上裹携的冰川泥沙后,湖水变得清澈碧蓝。在湖西南角的日内瓦,罗讷河走了出去,继续纵穿法国,最后在法国南部进入地中海。因为世界名城日内瓦位于湖的 Life is fragile, and it is far harder to resume it than to kill it. Scientists have found the main source of phosphorus death salt lake. Apart from sources of industrial pollution, another major source is actually what is being made everyday in people’s daily life - domestic sewage. The Rhone River, originating from the Rhone Glacier in the Alps, runs down the valley of Valle in southern Switzerland and merges into a large lake of 8,000 square kilometers. After settling the sediments of glaciers and muddy sediments in the lake, the lake became clear and blue. In Geneva in the southwest corner of the lake, the Rhône walked out to continue through France and finally to the Mediterranean in the south of France. Because the world famous city of Geneva is located in the lake
