4、to rot on dry land by a receding sea. Then imagine dust storms sweeping up toxic pesticides and chemical fertilizers from the dry seabed and spewing them across towns and villages.Seem like a scene from a movie about the end of the world? For people living near the Aral sea (咸海) in Central Asia, its
5、 all too real. Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate (provide water for ) farmland. As a result, the sea has shrunk to half its original size, stranding (使搁浅) ships on dry land. The seawater has tripled in salt content and become pollut
6、ed, killing all 24 native species of fish.Similar large-scale efforts to redirect water in other parts of the world have also ended in ecological crisis, according to numerous environmental groups. But many countries continue to build massive dams and irrigation systems, even though such projects ca
7、n create more problems than they fix. Why? People in many parts of the world are desperate for water, and more people will need more water in the next century. “Growing populations will worsen problems with water,” says Peter H.Gleick, an environmental scientist at the Pacific Institute for studies
8、in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as one-third of the worlds projected (预测的) 8.3 billion people will suffer from water shortages. WHERE WATER GOESOnly 2.5 percent of all water on Earth is freshwater, water suitab
9、le for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Two-thirds of this freshwater is locked in glaciers (冰山) and ice caps （冰盖）. In fact, only a tiny percentage of freshwater is part of the water cycle, in which water evaporates and rise
10、s into the atmosphere, then condenses and falls back to Earth as precipitation (rain or snow). Some precipitation runs off land to lakes and oceans, and some becomes groundwater, water that seeps into the earth. Much of this renewable freshwater ends up in remote places like the Amazon river basin i
11、n Brazil, where few people live. In fact, the worlds population has access to only 12,500 cubic kilometers of freshwaterabout the amount of water in Lake Superior(苏必利尔湖). And people use half of this amount already. “If water demand continues to climb rapidly,” says Postel, “there will be severe shor
12、tages and damage to the aquatic (水的) environment.”CLOSE TO HOMEWater woes(灾难) may seem remote to people living in rich countries like the United States. But Americans could face serious water shortages, too especially in areas that rely on groundwater. Groundwater accumulates in aquifers (地下蓄水层)，lay
13、ers of sand and gravel that lie between soil and bedrock. (For every liter of surface water, more than 90 liters are hidden underground.) Although the United States has large aquifers, farmers, ranchers, and cities are tapping many of them for water faster than nature can replenish(补充 ) it. In north
14、west Texas, for example, overpumping has shrunk groundwater supplies by 25 percent, according to Postel. Americans may face even more urgent problems from pollution. Drinking water in the United States is generally safe and meets high standards. Nevertheless, one in five Americans every day unknowin
15、gly drinks tap water contaminated with bacteria and chemical wastes, according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell ill in 1993 after drinking tap water tainted with cryptosporidium (隐孢子虫)，a microbe (微生物) that causes fever, diarrhea (腹泻) and vomiting.THE SOURCEWh
16、ere so contaminants come from? In developing countries, people dump raw (未经处理的) sewage(污水) into the same streams and rivers from which they draw water for drinking and cooking; about 250 million people a year get sick from water borne (饮水传染的) diseases.In developed countries, manufacturers use 100,00
17、0 chemical compounds to make a wide range of products.Toxic chemicals pollute water when released untreated into rivers and lakes. (Certain compounds, such as polychlorinated biphenyls (多氯化联二苯)，or PCBs, have been banned in the United States.)But almost everyone contributes to water pollution. People
18、 often pour household cleaners, car antifreeze, and paint thinners (稀释剂) down the drain; all of these contain hazardous chemicals. Scientists studying water in the San Francisco Bay reported in 1996 that 70 percent of the pollutants could be traced to household waste.Farmers have been criticized for
19、 overusing herbicides and pesticides, chemicals that kill weeds and insects but insects but that pollute water as well. Farmers also use nitrates, nitrogen-rich fertilizer that helps plants grow but that can wreak havoc (大破坏) on the environment. Nitrates are swept away by surface runoff to lakes and
20、 seas. Too many nitrates “over enrich” these bodies of water, encouraging the buildup of algae, or microscopic plants that live on the surface of the water. Algae deprive the water of oxygen that fish need to survive, at times choking off life in an entire body of water.WHATS THE SOLUTION?Water expe
21、rt Gleick advocates conservation and local solutions to water-related problems; governments, for instance, would be better off building small-scale dams rather than huge and disruptive projects like the one that ruined the Aral Sea.“More than 1 billion people worldwide dont have access to basic clea
22、n drinking water,” says Gleick. “There has to be a strong push on the part of everyonegovernments and ordinary peopleto make sure we have a resource so fundamental to life.”提示:在实考试卷中，8-10 题在答题卡 1 上。1.
