Coal, oil, natural gas, and all other fuels are stored energy from the sun. Some was collected by this season's plants as carbon compounds. Some was stored by plants and trees ages ago. Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power. Light transmits only the energy that comes from the sun's outer layer, and much of this energy that is directed towards the earth never arrives. About nine tenths of it is absorbed by the atmosphere of the earth. In fact, the earth itself gets only one half millionth of the sun's entire output of radiant energy.

Arthur von Wiesenberger, who carries the title Water Master, is one of the few water criticsin North America. As a boy, he spent time in the larger cities of Italy, France and Switzerland,where bottled water is consumed daily. Even then, he kept a water journal, noting the brands heliked best “my dog could tell the difference between bottled and tap water, ” He says.
But is plain tap water all that bad? Not at all. In fact. New York&39;s municipal water for more than a century was called the champagne of lap water and until recently considered among the bestin the world in terms of both taste and purity. Similarly, a magazine in England found that tapwater from the Thames River tasted better than several leading brands of bottled water that were400 times more expensive.
Nevertheless, soft-drink companies view bottled water as the next battle-ground for market share-this despite the fact that over 25 percent of bottled water comes from tap water: PepsiCo&39;sAquafina and Coca-Cola&39;s Dasani arc both purified tap water rather than spring water.
As diners thirst for leading brands, bottlers and restaurateurs salivate(垂涎)over the profits. A restaurant&39;s typical mark-up on wine is 100 to 150 percent, whereas on bottled water it&39;s often 300 to 500 percent. But since water is much cheaper than wine, and many of the fancier brands aren&39;t available in stores, most diners don&39;t notice or care.
As a result, some restaurants are turning up the pressure to sen bottled water.According to an article in The Street Journal, some of the more shameless tactics include placing attractivebottles on the table for a visual sell, listing brands on the menu without prices, and pouring bottledwater without even asking the diners if they want it.
Regardless of how it?s sold, the popularity of bottled whaler taps into our desire for betterhealth, our wish to appear cultivated, and even a longing for lost purity.

请帮忙给出每个问题的正确答案和分析,谢谢!
The region's accelerating population, expanding agriculture, industrialization, and higher living standards demand more freshwater. Drought and pollution limit its availability. War and mismanagement waste it. Said Joyce Start of the Global Water Summit Initiative, based in Washington, D.C. "Nations like Israel and Jordan are swiftly sliding into that zone where they are suing all the water resources available to them. They have only 15 to 20 years left before their agriculture, and ultimately their food security, is threatened."
I came here to examine this crisis in the making, to investigate fears that "water wars" are imminent, that water has replaced oil as the region's most contentious commodity. For more than two months I traveled through three river valleys and seven nations--from southern Turkey down the Euphrates River to Syria, Iraq, and on to Kuwait; to Israel and Jordan, neighbors across the valley of the Jordan; to the timeless Egyptian Nile.
Even amid the scarcity there are haves and have-nots. Compared with the United States, which in 1990 had freshwater potential of 10,000 cubic meters (2.6 million gallons) a year for each citizen, Iraq had 5,500, Turkey had 4,000, and Syria had more than 2,800. Egypt's potential was only 1,100. Israel had 460. Jordan had a meager 260. But these are not firm figures, because upstream use of river water can dramatically alter the potential downstream.
Scarcity is only one clement of the crisis, Inefficiency is another, as is the reluctance of some water-poor nations to change priorities from agriculture to less water-intensive enterprises. Some experts suggest that if nations would share both water technology and resources, they could satisfy the region's population, currently 159 million. But in this patchwork of ethnic and religious rivalries, water seldom stands alone as an issue. It is entangled in the politics that keep people from trusting end seeking help from one another. Here, where water, like truth, is precious, each nation tends to find its own water end supply its own truth.
As Israeli hydrology professor Uri Shamir told me: "If there is political will for peace, water will not be a hindrance. If you want reasons to fight, water will not be a hindrance. If you want reasons to fight, water will give you ample opportunities."
