Content of the presentation: • Studytheevolutionarytrend of structuralchanges • over a largesample of countries (82) 1980-2007 • showingtheexistence of a clear attractor 2. A comparison of EU14 1992-2005 showingthe existenceof clear benchmarksdescribingthe metaboliccharacteristics offunctional compartments of society 3. Conclusions
Would you believe someone telling you that at the next World Cup the players of the various EU national teams, during the month of that competition, will eat ¼ of what they eat now, and will generate a ¼ of the excrements they generate now?

The Olduvai Theory of Industrial Civilization 1. Pre Industrial Phase [c. 3 000 000 BC to 1765] A - Tool making (c. 3 000 000 BC); B - Fire used (c. 1 000 000 BC); C - Neolithic agricultural revolution (c. 8 000 BC); D - Watts steam engine of 1765 starting the Industrial Phase (1930-2025) 2. Industrial Phase [1930 to 2025, estimated] E - Per capita energy-use 37% of peak value; F - Peak energy-use; G - Present energy-use; H - Per capita energy-use 37% of peak value 3. Post Industrial Phase [c. 2100 and beyond] J, K, and L = Recurring future attempts at industrialization fail.
