This suggests that politic
3、ians who claim environ mentalism is yesterdays issue may be seriously misjudging the public mood. A report from Mintel, the market research organization, says that despite recession and financial pressures, more people than ever want to buy environmentally friendly products and a “green wave“ has sw

The recently published report also predicts that the process will repeat itself with “ethical“ concerns, involving issues such as fair trade with the Third World and the social record of businesses.

Mintels survey, based on nearly 1,000 consumers, found that the proportion who look for green products and are prepared to pay more for them has climbed from 53 per cent in 1990 to around 60 per cent in 1994. On average, they will pay 13
6、per cent more for such products, although this percentage is higher among women, managerial and professional groups and those aged 35 to 44. Between 1990 and 1994 the proportion of consumers claiming to be unaware of or unconcerned about green issues fell from 18 to 10 percent but the number of gree

According to Mintel, and image of green consumerism as associated in the past with the more eccentric members of society h

She explained that as far as the average person is concerned environmentalism has not gone off the boil. In fact, it has spread across a much wider range o
9、f consumer groups, ages and occupations. Mintels 1994 survey found that 13 per cent of consumers are “very dark green“, nearly always buying environmentally friendly products, 28 per cent are “dark green“, trying “as far as possible“ to buy such products, and 21 per cent are “pale green“tending to b

Only 10 per cent say they do not care about green issues. Four in ten people are “ethical spenders“, buying goods whi

This figure is the same as in 1990, although the number of armchair ethicals has risen from 28 to 35 per cent and only 22 per cent say they are unconcerned now, against 30 per cent in 1990. Hughes claims that in the twenty-first centu

42、 a hillside or other such obstruction. Sound travels at the rate of about one-fifth of a mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel to the hill and back. Thus, by timing the interval between a sound and its reflection (the echo), you can es
43、timate the distance to an obstruction. During World War I1 the British used a practical application of this principle to detect German planes on their way to bomb London before the enemy was near the target. They used radio waves instead of sound waves, since radio waves can penetrate fog and clouds
44、. The outnumbered Royal Air Force (RAF) always seemed to the puzzled Germans to be lying in wait at the right time and never to be surprised (袭击). It was radio echoes more than anything else that won the Battle of Britain. Since the radio waves were used to tell the direction in which to send the RA
45、F planes and distance to send them ( their range of flight, in other words), the device was called radio directing and ranging, and from the initials the word radar was coined.
