Sure Al. Those of us that care about the quality of life on the planet are whiners and those of you fascinated by cheap and fast are what? Give it a break.

No doubt you would have been one of those people in Medieval Europe complaining about those biowhiners who wanted you to stop throwing your toilet slop into the street.

10,000+ years of doing it your way has taken us to here. Perhaps not repeating the same insanity for another 10,000 years might produce different, and better, results.
