We must destroy the earth to save it because only after a concerted effort to deliberately destroy the planet and failing will certain of us self-centered humans realize the planet can take care of itself. As for getting "unaddicted" to oil, we should buy gas guzzlers and drive everywhere for no reason until there is no oil left (which I believe the earth makes her own oil but that is beside the point) because only when an energy source as economical as oil is depleted will any other alternative make any sense. Then I hope it is the Mr. Fusion from Back to the Future and not something that doesn't work when it is cloudy, like solar panels.
Rush replayed the time that Charlton Heston came on the show to read from Michael Cricghton's Jurassic Park about the time in earth's history when plants were destroying the planet by producing too much of their waste product which we all breath today. The earth, not having a political agenda, simply took care of it as did life that wanted to survive.
Which brings us to this quote from Brundle Fly:
Seth Brundle: You have to leave now, and never come back here. Have you ever heard of insect politics? Neither have I. Insects... don't have politics. They're very... brutal. No compassion, no compromise. We can't trust the insect. I'd like to become the first... insect politician. Y'see, I'd like to, but... I'm afraid, uh...
Ronnie: I don't know what you're trying to say.
Seth Brundle: I'm saying... I'm saying I - I'm an insect who dreamt he was a man and loved it. But now the dream is over... and the insect is awake.
Ronnie: No. no, Seth...
Seth Brundle: I'm saying... I'll hurt you if you stay.
Although I would say knowing the insect doesn't have politics make them far more honest than many humans. What we can't trust is an insect pushing an agenda.
