Colin Campbell, a real geophysicist, who therefore understands the finite capacity we have of producing marketable flow, once described the "controversy" over peak oil as being between the geologists and economists. That's realist versus idealist. Please understand that Duncan Clarke is the latter - an economists. But of the worst sort, someone with the wherewithal to spread deceit as just another economic hit man. Such men live in a fantasy world where human ingenuity is supposedly able to overcome any practical limits of reality, whether those limits are geological constraints, workers, or human conscience. Those with fortunes to protect, based on the London and New York merchantile exchanges, the house of cards built with petrodollar recycling and its many derivatives, are now in stark raving fear mode. Such economists would have us believe in schemes of continued investment in all that petroleum and natural gas infrastructure. After all, there really are fortunes to protect. The immanent collapse of the growth economy, and all that serves, is indeed fearsome. Investors have shown quite the propensity to panic in the markets, and must not let that happen, now should we? Better to keep the dream alive, huh? To concoct fantasies of ever more available petroleum reserves and to dismiss the half century of sound geological science on which modern predictions of an immanent peak in world productive capacity are based, is dangerous to the extreme. Like the pied piper of old, Duncan would lead us where we must not go. Don't bother reading the book, if it is even readable. Stay focused in reality, and please make wise investment choices, of which there are many to choose.
