問題詳情

四、閱讀測驗    Since the 1990s, garbage disposal companies have been recycling what they can—glass, plastic, electronics, evenconcrete—and incinerating the rest. The Tuas South incineration plant, the largest and newest of four plants run by theSingapore government, is tucked away in the southwest part of the main island. A recent visit by a group of scientists found itsurprisingly clean and fresh. The incinerator creates a weak vacuum that sucks the foul air from the trash-receiving room in tothe combustion chamber.    Not that incineration is problem-free. When Singapore began burning garbage, its carbon emissions into the atmosphererose sharply while its solid carbon deposits dropped, according to data gathered by the Oak Ridge National Laboratory inTennessee. During the last couple of years, however its emissions have stabilized. The recycling program has been moreeffective than anticipated.    Once Singapore started burning trash, the big question was where to put the ash. The government then built aseven-kilometer-long rock bund to connect two offshore islands, Semakau and Sekang, and named the new island PulauSemakau. The complex cost about 610 million Singapore dollars, approximately US$400 million. This is no ordinary landfill:the island doubles as a biodiversity hotspot, of all things, attracting rare species of plants and animals. It even attractsecotourists on specially arranged guided tours. Eight years in the making, the artificial island is setting an example for thefuture of conservation and urban planning.    One complaint about Pula Semakau was that it called for the destruction of mangroves on part of the original island. ButSingapore’s National Environmental Agency saw to it that the mangroves were replanted in areas adjoining the landfill. Allmangroves survive and continue growing. The island now has more than 13 hectares of mangroves, which serve as a habitatfor numerous species.    This is why the rest of the world should be watching: time will tell whether Semakau is a useful model for conservation,also as a benchmark of one aspect of successful and sustainable urbanization. Meanwhile the Singapore government, with itsthriving ecosystem, wants it to become a permanent nature reserve.
