The great tragedy of science is the slaying of a beautiful theory by an 
ugly fact.

I still maintain, however, for a society with that much of a population 
problem that they'd need a ringworld, they should have already created a 
quick and easy way to terraform. Just think of the time, effort, and 
knowledge necessary to build a ringworld. Then compare that to the 
requirements of terraforming.
