The earth is witnessing an urban
revolution, as people worldwide crowd into towns and cities. In 1800 only five
per cent of the world’s population were urban dwellers; now the proportion has
risen to more than forty-five percent, and by the year 2010 more people will
live in towns and cities than in the countryside. Humanity will, for the first
time, have become a predominantly urban species.
Though the
world is getting more crowded by the day, absolute numbers of population are
less important than where people concentrate and whether these areas can cope
with them. Even densities, however, tell us nothing about the quality of the
infrastructure—roads, housing and job creation, for example—or the availability
of crucial services.
The main question, then, is not how many
people there are in a given area, but how well their needs c
A. to warn about the dangers of revolutions in towns
B. to warn about the possibility of a population explosion
C. to suggest governments should change their priorities
D. to suggest governments invest in more housing in cities
