One future possibility

This afternoon I sat through a recorded NOVA program on dirty bombs. I remember reading about threats a while ago, but didn't know what a dirty bomb was.

So much new terminology has permeated our vocabulary, it's hard to keep up with what's what.

Getting back to the program... One scientist explained that because of the prohibitive costs of cleaning up radiation in a city the size of London or Paris or New York, one viable option would be to abandon the contaminated area. And then the next scene was a dramatization of London.... deserted. Watching that, I felt a shiver make its way up my spine.

Is that what we have to look forward to? Will we be forced to abandon our cities? And where would all of the urbanites move to? Is smalltown USA in danger of one day becoming the next Big Apple?
