10、ood,says SandraPostel,director of the Global Water Policy Project in Amherst,Mass.Two thirds ofthis freshwater is locked in glaciers(冰 山)and ice caps(冰 盖).In fact,only a tinypercentage of freshwater is part of the water cycle,in which water evaporates andrises into the atmosphere,then condenses and
11、falls back to Earth as precipitation(rainor snow).Some precipitation runs off land to lakes and oceans,and some becomesground water,water that seeps into the earth.Much of this renewable freshwater endsup in remote places like the Amazon river basin in Brazil,where few people live.Infact,the world s
12、 population has access to only 12,500 cubic kilometers of freshwater about the amount of water in Lake Superior(苏 必 利 尔 湖).And people use half ofthis amount already.If water demand continues to climb rapidly,says Postel,“there will be severe shortages and damage to the aquatic(水 的)environment.CLOSE
13、TO HOMEWater woes(灾 难)may seem remote to people living in richcountries like the United States.But Americans could face serious water shortages,too especially in areas that rely on groundwater.Ground water accumulates in aquifers(地 卜 蓄 水 层),layers of sand and gravel that lie between soil and bedrock

16、to the Environmental Protection Agency.InMilwaukee,400,000 people fell ill in 1993 after drinking tap water tainted withcryptosporidium(隐 抱 子 虫),a microbe(微 生 物)that causes fever,diarrhea(腹 泻)and vomiting.THE SOURCE Where so contaminants come from?In developingcountries,people dump raw(未 经 处 理 的)sew
