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 dump site. Residents or trash haulers (垃圾托运经营者) 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 modem society. The first problem is space. Dumps, which are now called landfills, are most
A. burying it
B. recycling it
C. burning it
D. throwing it into rivers
