The London Times has an article that shows quite clearly why using paper bags and Toyota Priuses may well be beneficial for all sorts of things, but they contribute absolutely nothing to saving the world from global warming. The argument is actually quite simple: the oil producers will produce the same amount no matter who buys from them and even, within a reasonable range, no matter what the price. So although being green is rapidly becoming an article of faith among many westerners, the most that their actions will achieve will be that the oil will be consumed elsewhere, which amounts to the same from the perspective of global warming.
The alternative? To develop real alternatives to oil.
I'm already on record for my opinion about global warming. I do however admit to being quite gleeful when it comes to disproving the sanctimonious, unthinking masses who subscribe to the new religions of our age. Religions, it seems to me, require half a millennium or three of deep thought and deliberation before they mature; the ones that have been invented since 1945 seem to me mostly silly.
