This guy's DVD on exponential growth, money, population, and "peak everything" is now free to watch online AND he'll even sell you an actual DVD that is Creative Commons so that you can copy it and give it to others. I'm convinced that this generation has to figure this out now, that the planetary limits of our population and consumption start to bite over the next 10 to 20 years, and
Dr Chris Martenson's work is as good a summary as anyone's I've read/watched.
