The problems with
urbanization are
growing cities tend to
absorb arable land;
the number of food
producers decreases;
it becomes
progressively more
difficult to scale up
infrastructure; and  
disasters and diseases
have increasingly
juicier targets. On the
other hand, humans
have been building
cities for at least
10,000 years.

Largest cities by population.
The arguments among geographers about what defines a city, especially as distinguished from a
metropolitan area are endless. Stockton, Chula Vista, Irvine, Fremont, Modesto, San Bernardino
and Glendale all have over 200,000 people. The LA-LB-SA metro statistical area has 13 million.
Fewer cities, smaller cities. Advantage: Sudan.
