SHORT ANSWER

16. ANS:
If the landfill is close to the city, residents of the city would not want to live near it, would see the value of their property decline, and would most likely organize protests against having the landfill close by. If the landfill is far from the city, trucks would have to drive the garbage long distances to dispose of it. This would lead to high costs to taxpayers for gas, oil, and road and truck maintenance, and would also contribute to air pollution.

PTS: 1 DIF: 3 REF: 1 OBJ: 3

17. ANS:
Some waste simply does not burn; incinerators give off a certain amount of toxic particles and gases, even with pollution control devices; and the ash that remains after the waste is burned must still be disposed of.

PTS: 1 DIF: 3 REF: 1 OBJ: 2

18. ANS:
The first way is to produce less waste, such as choosing products with as little packaging as possible. The second way is to recycle, which saves resources and energy. The third way is to change the materials we use, as in developing truly biodegradable “plastics.”
