What would happen if consumers decided to simplify their lives and spend less on material goods and services This question is taking on a certain urgency as rates of economic growth continue to decelerate through the industrialized world, and as millions of consumers appear to be opting for more frugal lifestyles. The Stanford Research Institute, which has done some of the most extensive work on the frugality phenomenon, estimates that nearly five million American adults are pursuing lives of "voluntary simplicity", and double that number "adhere to and act on some but not all" of its basic tenets.

The frugality phenomenon first achieved prominence as a middle-class rejection of high consumption lifestyle in the industrialized world during the 1950s and 1960s. In The Silent Revolution, Ronald Inglehart of the University of Michigan’s Institute of Social Research examined this experience in the United States and 10 Western European nations. He concluded that a change has taken place "from an overwhelming emphasis on material well-being and physical security toward greater emphasis on the quality of life," that is, "a shift from materialism to post-materialism. "

Inglehart calls the 1960s the "fat years". Among their more visible trappings were the ragged blue jeans favored by the affluent young. Most of the retreat from materialism, however, was less visible. Comfortably fixed Americans were going without change, making things last longer, sharing things with others, learning to do things for themselves and so on. But while economically significant, it was hardly discernible in a US Gross National Product climbing vigorously toward the $ 2 thousand billion mark.

Yet as the frugality phenomenon matured—growing out of the soaring 1980s and into the sober 1990s—it seemed to undergo a fundamental transformation. American consumers continued to lose faith in materialism and were being joined by new converts who were embracing frugality because of the darkening economic skies they saw ahead. Resource scarcities, soaring energy prices, persistent inflation, high-level unemployment, balance-of-trade deficits, the declining value of the US dollar on foreign exchange markets forced consumers to look to their own resources. The one device which seemed most promising, the one over which they had the most control, was frugality—learning to live with less in a world where a penny saved was still a penny earned.

According to Inglehart, the frugality phenomenon ().

A. began to be noticed in the industrialized world during the 1950s and 1960s

B. was an old phenomenon in the disguise of a new cloak

C. indicated a turn of people’s attention to the quality of life

D. was more visible among the affluent young

     Elephants and people are in competition for space. In much of Africa, elephants are now put in

national parks. Elephants suffered a serious and steady decrease in numbers in the 1970s. This wa

s the same time when scientists were beginning to learn a great deal about elephants and their behavior.

Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of

communication.

     In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 to

25,000. The sharp drop in numbers was the result of poachers (偷猎者) illegally killing elephants for

their ivory. The price of ivory went from $3 a pound to $50 to $100 a pound. Africa became very

attractive to poachers. Bull elephants carried the largest tusks (象牙), so they were more often killed.

With males gone and older females killed by poachers as well, there were many young elephants unable

to benefit from the wisdom of the older females and matriarchs, who lead the herds.

     Kenya took a stand, international trade in ivory was officially forbidden, and $3,000,000 worth of

confiscated (没收的) ivory was burned in Kenya. The following year, only 50 elephants were lost to

poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world.

People throughout Africa won't tolerate elephants eating their crops and destroying their livelihoods.

     In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game

hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there were some attempts at birth control to keep the elephant population at

manageable numbers to reduce conflicts with people.

     Faced with a growing human population, elephants are losing the battle for space. It's unlikely, though,

that they will become extinct. They will live in natural parks that bring tourists to Africa as well as India

and other parts of Asia. The money from tourism will help elephants to survive.
