I'm beginning to think, more and more, that global climate change and Peak Oil are opportunities rather than problems, the old Chinese course.
Besides being environmentally unsustainable, human society has been largely dominated by, well, dominating types! The meek have never inherited the earth, even if they ever wanted it in the first place. Under present conditions, the meek are easily dominated by the strong and willful, who have monopolized access to energy and power for their own dominating purposes.
That's all changing now as Peak Oil begins to take a bigger bite, and global climate change really threatens the continuance of human life. A world of less energy will necessarily b a world of less central control, as it takes energy to maintain far-flung control systems.
