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

4、 sea (咸海) in Central Asia, its 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 s

But many countries continue to build massive dams and irrigation systems, ev

6、en though such projects can 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 Paci

7、fic Institute for studies 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

8、 freshwater, water suitable 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

9、water evaporates and rises 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

10、the Amazon river basin in 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, “t

11、here will be severe shortages 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

12、 in aquifers (地下蓄水层), layers 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 re

13、plenish(补充 ) it. In northwest 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 Amer

14、icans every day unknowingly drinks tap water contaminated with bacteria and chemical wastes, according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell iii in 1993 after drinking tap water tainted with cryptosporidium (隐孢子虫), a microbe (微生物) that causes fever, diarrhea (腹泻)

15、and vomiting.THE SOURCEWhere 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

16、, manufacturers use 100,000 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 contribute

17、s to water pollution. People 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.Farm

18、ers have been criticized for overusing herbicides and pesticides, chemicals that kill weeds and insects but insects but that pollutes water as well. Farmers also use nitrates, nitrogenrich fertilizer that helps plants grow but that can wreak havoc (大破坏)on the environment. Nitrates are swept away by

19、surface runoff to lakes and seas, Too many nitrates “over-enrich“ these bodies of water, encouraging the buildup of algae, or microscopic plants that live on the surface of tile water. Algae deprive the water of oxygen that fish need to survive, at times choking off life in an entire body of water.W

20、HATS THE SOLUTION?Water expert Gleick advocates conservation and local solutions to water-related problems; governments, for instance, would be better off building smallscale dams rather than huge and disruptive projects like the one that ruined the Aral Sea.“More than I billion people worldwide don

21、t have access to basic clean 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.“2 That the huge water projects have diverted the rivers causes the Aral Sea to shrink.（A）Y（B） N（C） N
