But the human spirit to continue is stronger than any freaking oil crisis
I'm sure the spirit to continue was strong on Easter Island as well. It still didn't stop people from dying when they depleted their key resource.
You can't eat willpower.
The root of the problem is too many people, too much exponential growth, and not enough resources to sustain it. The ultimate solutions are to either
1. Find an infinite source of energy in this finite world so growth can be sustained until the Earth is 1 person per square meter on the dry-land surface of the planet and the globe glows hot from electricity usage, or
2. Controlling the population, or
3. Let nature take care of the population problem.
Either way, the problem is going to be taken care of. It's just a hell of a lot easier if we're the ones doing the controlling.
Any of you guys that are still under the illusion that we're going to have anywhere near the energy capacity of today post-peak are missing the issue entirely.
Energy resources must produce more energy than they consume, otherwise they are called "sinks" (this is known as the "net energy" principle). About 735 joules of energy is required to lift 15 kg of oil 5 meters out of the ground just to overcome gravity -- and the higher the lift, the greater the energy requirements. The most concentrated and most accessible oil is produced first; thereafter, more and more energy is required to find and produce oil. At some point, more energy is spent finding and producing oil than the energy recovered -- and the "resource" has become a "sink".
There is an enormous difference between the net energy of the "highly-concentrated" fossil fuel that power modern industrial society, and the "dilute" alternative energy we will be forced to depend upon as fossil fuel resources become sinks.
No so-called "renewable" energy system has the potential to generate more than a tiny fraction of the power now being generated by fossil fuels!

Energy Synopsis
The end of growth in consumption of energy means the end of growth. That means the population cannot grow, energy use cannot grow, and the economy cannot grow.
The same also holds true for decline in energy resources. Everything follows.
