In our society the razor of necessity cuts close. You must make a buck to survive the day. You must work to make a buck. The job is often a chore, rarely a delight. No matter how demeaning the task, no matter how it dulls the senses or breaks the spirit, one must work. Lately there has been a questioning of this "work ethic", especially by the young. Strangely enough, it has touched off profound grievances in others hitherto silent and anonymous.
Unexpected precincts are being heard from in a show of discontent by blue collar and white. On the evening bus the tense, pinched faces of young file clerks and elderly secretaries tell us more than we care to know. On the expressways middle-management men pose without grace behind their wheels, as they flee city and job.
In all, there is more than a slight ache. And there dangles the impertinent question: Should there not be another increment, earned though not yet received, to one’s daily work—an acknowledgment of a man’s being In fact, what all of us are looking for is a calling, not just a job. Jobs alone are not being enough for people.

The "work ethic" in the first paragraph can be interpreted as （）

A. adequate but primitive
B. inhumane and inadequate
C. humane but crowded
D. similar to the crew’s quarters

Americans have responded to Lebow’s call, and much of the world has followed.
Consumption has become a central pillar of life in industrial lands and is even embedded in social values. Opinion surveys in the world’s two largest economies—Japan and the United States—show consumerist definitions of success becoming ever more prevalent.
Overconsumption by the world’s fortune is an environmental problem unmatched in severity by anything but perhaps population growth. Their surging exploitation of resources threatens to exhaust or unalterably spoil forests, soils, water, air and climate.
Ironically, high consumption may be a mixed blessing in human terms, too. The time-honored values of integrity of character, good work, friendship, family and community have often been sacrificed in the rush to riches.
Thus many in the industrial lands have a sense that their world of plenty is somehow hollow—that, misled by a consumerism culture, they have been fruitlessly attempting to satisfy what are essentially social, psychological and spiritual needs with material things.
Of course, the opposite of overconsumption—poverty—is no solution to either environmental or human problems. It is infinitely worse for people and bad for the natural world too. Dispossessed (被剥夺得一无所有的) peasants slash-and-burn their way into the rain forests of Latin America, and hungry nomads (游牧民族) turn their herds out onto fragile African grassland, reducing it to desert.
If environmental destruction results when people have either too little or too much, we are left to wonder how much is enough. What level of consumption can the earth support When does having more cease to add noticeably to human satisfaction
