Does all this mean environmental concerns have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. "I guess people believe that the problem is taken care of, because of recycling," said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.

Anyone with a passion for hanging labels on people or things should have little difficulty in recognizing that an appropriate tag for our time is the Unkempt Generation. I am not referring only to college kids. The sloppiness(邋遢) virus has spread to all sectors of society," People go to all sorts of trouble and expense to look uncombed, unshaved, unpressed.

The symbol of the times is blue jeans -- not just blue jeans in good condition but jeans that are torn and discolored. They don't get that way naturally. No one wants blue jeans that are clean or brand new. Manufacturers recognize a big market when they see it, and they compete with one another to offer jeans that are made to look as though they've just been thrown away by clumsy house painters after ten years of wear. The more faded and seemingly ancient the garment, the higher the cost. Untidiness is in fashion; neatness is out of date.

Nothing is wrong with comfortable clothing. It's just that current usage is more reflective of a blind conformity than a desire for ease. No generation has tried harder than ours to fake a casual, relaxed, cool look; none has succeeded more impressively in looking as though it had been stamped out by cookie cutters(模具). We desperately keep ourselves from being conventional, but we put on a uniform to do it. An appearance of radical difference is the goal, to be pursued in oversize sweaters and muddy sports shoes.

Careless speech stems from the same root. Vocabulary, like blue jeans, is being drained of colour and distinction. A complete sentence in everyday speech is becoming increasingly rare. People communicate in chopped-up phrases, relying on something like "you know" or "I mean" to cover up annoyingly unclear expressions. Neatness should be no less important in language than it is in dress. The English language is one of the greatest sources of wealth in the world. In the midst of accessible riches, we are still sadly poor in language.
