问题     Australia’s population passed 18 million for the first time in March this year.
    But as Australia grows, environment groups yesterday urged the government to develop a national population policy to avoid severe environmental degradation(恶化).
    Australian Bureau of Statistics(ABS)research shows the birth or arrival of 68, 700 new Australians in the year to March pushed the population to 18, 000, 500.
    Victoria’ s population increased by 23, 000 to 4. 5 million in the year to March. The ABS also forecast the population would reach 20 million by 2006 and 24 million by 2033.
    Australia reached its first million in 1858.
    While immigration was responsible for a large part of the population booms in the past, over the last five years new born made up 68 percent of the 1 million increase in population.
    Australia has one of the lower population growth rates in the region, with New Zealand growing at 1.4 percent. Indonesia at 1. 7 percent and PNG at 2 percent, ABS spokesman Mr. John Paice said.
    Australians for an Ecologically Sustainable Population: a group of 560 academics, scientists and public, yesterday urged the government to develop a sustainable population strategy to avoid further land and water degradation.
    National ALP president Barry Jones last year chaired a parliamentary inquiry into what population levels Australia could reach without risking serious pollution and degradation problems.
    Many of the opinions to the inquiry suggested a population limit of 17-23 million. The government was expected to respond to the Jones report by July, but did not.
    CSIRO research scientist Dr. Doug Cocks agreed the government needed to develop a population policy.
    "With population size(inAustralia)doubling every 40 to 50 years, we would need another couple of Melbournes and Sydneys by 2050, "Dr. Cocks said.

As population grows, environment experts may be concerned about all the following except______.
选项 A、water resources
B、food supplying
C、housing
D、radioactive pollution
答案D
解析 本题是细节推理题。从文章第2段中“several environment degradation(严重的环境恶化)”和第8段中“further land and water degradation(进一步的土地和资源水的恶化)”可以判断环境专家对选项A的关注，另外，人口过度增长，势必带来食品供应(food supplying)和住房(housing)等问题。而选项D(radioactive pollution，放射性污染)并不是人口过多的必然结果，所以不在环境专家的关注范围内。
