我想要这篇的译文The advantages and disadvantages of a large population .
The advantages and disadvantages of a large population have long been a subject of discussion among economists.It has been argued that the supply of good land is limited.To feed a large population,inferior land must be cultivated and the good land worked intensively.Thus,each person produces less and this means a lower average income than could be obtained with a smaller population.Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports,roads and railways,which are not likely to be built unless there is a big demand to justify them.
One of the difficulties in carrying out a world-wide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials.In the developing country where a vastly expanded population is pressing hard upon the limits of food,space and natural resources,it will be the first concern of government to place a limit on the birthrate,whatever the consequences may be.In the highly industrialized society the problem may be more complex.A decreasing birthrate may lead to unemployment because it results in a declining market for manufactured good.When the pressure of population on housing declines,prices also decline and the building industry is weakened.Faced with considerations such as these,the government of a developed country may well prefer to see a slowly increasing population,rather than one which is stable or in decline.

人口多的优点和缺点,一直是经济学家讨论的主题之一,有人认为良好的土地是供应人口众多最少的条件,经济学家们认为劣质土地必须培养和耕种,因此,每个人生产较少,并且这比可能获得有更小的人口意味一项更低的平均收入人口众多,可以让更多的余地和发展专业化的设施,如港口,公路和铁路,不可能被修造,除非有维护他们的大需求.
