Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.

Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.

"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.

So hours of seemingly mindless eating grass may not be so mindless after all.

Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much individuality and are frightened of just about everything.

"All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.

In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.

"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. "
