While I've been enjoying reading Hausfrau's blog on Peak Oil, I was thrown when she called for people to give up their hopes for 'Starship Enterprises'. Give up the dream for a future with the promise of other planets and peoples to know? Never!
I grew up believing that humans could grow past their petty prejudices and xenophobia's; making a positive impact on the universe. While Star Trek certainly was the strongest influence, there were others; notably, Andre Norton's The Stars Are Ours.
Peak Oil may slow us down, but I hope we never give up the dream.
