The Tipping Point in Civilizational Collapse:

"Just as biological systems exhibit tipping points which once passed catalyze irreversible and often unpredictable patterns of change, so do civilizations and social structures. In past civilizational collapses, these tipping points were generally catalyzed by soil depletion, resource shortages, environmental degradation, and social upheaval [pesquisar neste blogue sob o nome "Jared Diamond"].

The Earth Policy Institute’s Lester Brown identifies many global factors which may be pushing industrial civilization beyond a tipping point of irreversible change and collapse. Overharvesting of marine fisheries, loss of biodiversity, increased population growth, poor food and water management, the peaking of oil production, social conflict, and climate change are among the pressures breaking down civil social structures."
