Peak Oil
I just had to mention this article about peak oil. It gives a nice, objective rundown about what this "peak oil" thing is all about. Quote of choice:
Cornucopians discount the threat Peak Oil represents by insisting that the market will adapt. Of course, they are correct, but they suffer a failure of imagination to consider what the market's adaptations might include. Genocidal warfare is a very efficient way to reduce demand, for example. As Tainter highlighted in Collapse of Complex Societies, collapse is an economizing process.
Food for thought...
