问题 In an early survey conducted in 1888，a billion and a half people inhabited the earth．Now．the population exceeds seven billion．This means that the world must accommodate a new population roughly equal to that of the United States and Canada every three years!Even though the rate of growth has begun to slow down，most experts believe the population size will still pass eight billion soon．
    If we examine the amount of land available for this ever-increasing population，we begin to see the problem．If everyone on the planet had an equal share of land，we would each haye about 50，000 square metres．This figure seems to be quite encouraging until we examine the type of land we would have．Not all land is useful to humans as it cannot produce food．We call cut out about one fifth of it because it is permanently covered by snow and ice．Then we can cut out another one fifth because it is desert．Another fifth is too mountainous or is too great a height above sea level．A tenth doesn’t have enough soil for crops to grow-it is bare rock．
    Obviously，with so little land to support us，we should be taking great care not to reduce it further．But are we?We are consuming its“capital”，which means its nonrenewable fossil fuels and other mineral deposits that took millions of years to form but which are now being destroyed in decades．We are doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils，groundwater and the millions of other species that share earth with us．
    The birth of a baby in，for example，Hong Kong，imposes more than a hundred times the amount of stress on the world’s resources as a baby in India．Most people in India do not grow up to own cars or air-conditioners．Nor do they eat the huge amount of meat and fish that the Hong Kong child does．Their life-styles do not require vast quantities of minerals and energy．Also，they ale aware of the requirements of the land around them and try to put something back into nature to replace what they take out．
What can we learn from the passage?
选项 A、Different lifestyles require similar quantities of resources．
B、A Hong Kong baby consumes more resources than an Indian baby．
C、Hong Kong doesn’t have as many resources as India
D、Most people in India are born in poverty．
答案B
解析 细节题。文章最后一段前两句讲到，一个香港出生的婴儿产生的世界资源压力会比一个印度出生的婴儿产生的多100倍，由此可以判断出，一个香港的婴儿消耗的资源比印度婴儿多，故选B。
