Exploding Cities -- Film Description:
"At the beginning of this century Earth was still a rural planet. By the year 2 000, two out of three of us will be living in cities. This film examines the causes of this massive migration, the terrible poverty that ensues, and what steps are being taken in some cities in the developing world to cope with the great influx of people."
