Introduction: We'll definitely need to tackle the subject one of these days...
When the engine dies (limits that cannot be crossed)
Leaving the road (boundaries that can be crossed)
Trapped in an ever more fragile vehicle
The difficulties of being a futurologist
Can we detect warning signs?
What do the mathematical models say?
And where do human beings fit into all this?
Conclusion: Hunger is only the beginning
