The future population will be older than today, and this in turn will change the patterns of social demands. However, Mexico will still be far from the aging societies that will most likely prevail in the industrialized countries. In less than 25 years, the country will have to add almost as much infrastructure as it has already built up to now, simply to maintain services and production at the current levels. This will be a tremendous challenge, although a similar one was faced successfully in the recent past, when available infrastructure was doubled in two decades or so. It is no wonder that much has been said about the need to reduce or preferably halt Mexicos population control which is taken for granted as both good and necessary. It has also gained supporters in the developing world, and Mexico is no exception. But the arguments about population are complicated, as the following discussion illustrates.
Even if Mexicos population reaches 125 million by the year 2010, its population density is still smaller than the 1985 population density of some 50 countries. By international standards Mexico will still not be overpopulated by the year 2010. If wealth is generated by people, the more individuals there are, the greater the wealth that potentially could be generated. Why should Mexico control its population at density levels below those of the richer countries if more population represents the possibility of generating more wealth?
On the other hand, it is often pointed out that once sustainability limits are near or are reached, there are decreasing productivity gains , and people become a cost rather than an asset. If we assume that there are sustainability limits and that we are close to reaching these limits at a world level, then it is appropriate to check population growth.

A. whether more people are a property or a cost
B. whether Mexico should control its population growth or not

D. It is not necessary for Mexico to develop its infrastructure.
23. By infrastructure the author means_______.

24. It may be inferred from the 3rd paragraph that_______.
A. it isnt necessary for Mexico to control its population growth
B. population is likely to grow at a slower pace than in the past
C. the more people there are, the greater the wealth people could generate
D. Mexico should control its population growth because she belongs to the developing countries
25. To check population growth is necessary when_______.
A. there are decreasing productivity gains
B. there are increasing productivity losses
C. we are close to reaching the sustainability limits at a world level
