Energy Crisis
One key question for the next century is how we provide energy in an environmentally sound way.
As living standards rise in the developing world, energy consumption will increasE.As a result, many countries are now opening the door for private investment in a sector that used once to be solely the preserve of government.
In the developed world, the move is towards the deregulation and privatization of electricity generation and distribution. There is also a trend towards locally-generated energy, particularly in the developing worlD.Factories and shopping centers may one day have their own power sources.
Progress is also being made in minimizing the environmental impact of energy production and consumption. A motor car today puts out perhaps 5 percent of the pollution a new car did in 1970. We can produce clean power too but it costs, so in the new millennium(一千年) we're to some extent going to have the environment we can afforD.
The spectre of scarce or impossibly expensive energy is no longer with us, thanks to a combination of opening up new regions of the world and new technologies. Shortage is very unlikely. Environmental considerations mean there is a seriousness too about alternative energy sources that wasn't there ten years ago.
Right now the fuel cell is at the top of the list of alternative technologies. Advances in turbine transportation mean that natural gas is going to have an ever-increasing rolE.Nuclear power may prove competitive enough to have a much longer life than many expect, but until there's a major change in public sentiment, I don't expect to see much new nuclear construction.
Will the grip of oil on personal transportation continue? Sports utility vehicles like Land Rovers and jeeps are hardly the perfect means of urban transport. But people have become very attached to their automobiles. So until we get around to technology where we beam ourselves around, I suspect we'll continue to have them. Some may be electric; others could run on cleaner oil-based fuel or natural gas.
One area which is certainly not clear is the impact of the internet on transport. On the one hand, you will be able to accomplish by sitting in front of a screen what you used to have to go to the airport for, on the otherhand, increased knowledge may well fuel a rising demand for travel. We are only at the beginning of a revolution that is already being called a bigger revolution than the internal combustion engine(内燃机).

Eating Meat—Less or More?Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one's diet is nutritionally, environmentally, and ethically beneficial.People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to A Teen's Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier.Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is truE.More than 80% of the corn and 95% of the oats grown in the U. S. are fed to livestock. The world's cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock; 250 gallons of water produces only 1 lB.of beeF.If people eat less meat and more plants, the amount of available food will increasE.Many people become vegetarians because they feel that eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half a square foot of space each, and since they are raised so close together, a lot of blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other's tails, so both their teeth and tails are removed as soon as they are born.Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and to the health of the worlD.Why do some people become vegetarians? ______A.They feel that eating animals is unethical.B.There are fewer livestock available due to the environmental pollution.C.The consumption of meat will lead to financial problem.D.Being a vegetarian is beneficial to the protection of water.
