>> The world will just keep rushing forward. Some have a slight hand in the direction it goes for better (never) or for worse, but spiral it will.

The systems are too large and self-propulsing for anyone to really control. Consider the rainforest. How many millions of variables interact, nobody is in charge, everything influences everything in a billion different ways. You might say, well we can cut it down, so kind we can control it. Allright, let's continue to spiral. You might build a city there after a few years. Still in charge right. But it get's too hot because there's no vegitation, so you have to change again. And then we find that people keep getting strangely sick, and scientists find some special mushroom that survived and apparantly thrives on the mix of cut trees and diesel fumes and their spores in the air are poisonous. I made that up, but you get the idea hopefully.
