Plant,
You raise interesting questions about how someone like Campbell could miss the shale oil revolution. I haven't watched the DVD.
I did watch, back in 2004, a documentary called "The End of Surburbia" and it was enlightening.
http://endofsuburbia.com/The End of Surburia was enlightening bc it went into detail about how energy is the foundation of everything, including our economics, and specifically went into how the two biggest drivers of the American economy, housing and cars, were built on cheap energy that wasn't sustainable. Basically, they trace the historical development of the car and housing. Housing and the auto industry were the drivers of the modern American economy from WWII onward. The documentary, released at the height of the housing boom, questioned whether an economy built on housing and cars could continue. I think they were right in suggesting it couldn't, and didn't, continue it is grotesque distorted growth.
Until watching that documentary, I never really appreciated the importance that "oil" and energy in general played in everything we do. I was ignorant and still am. However, I now have an appreciation for energy. I don't take it for granted.
"The End of Suburbia" is worth watching today. Its a good beginning for beginners and the truth of its questions and assertions have been proven over time, so no reason a beginner has to question the assumptions. They can watch and with their own recent experiences understand the questions and concerns raised are legitimate and then move onto how to we handle the issues. The themes presented are true today, higher costs for everything force the view to consider what is sustainable and what is more realistic. It changed my outlook and helped me understand the world, politics, my own individual decisions. I think its worth watching.
