Complexity & Collapse
Why is the global economy constrained by the energy cost of energy? from GETTING DOWN TO EARTH: Practical Applications of Ecological Economics, Island Press, 1996; ISBN 1-55963-503-7 http://www.amazon.com/exec/obidos/ASIN/1559635037 Historical knowledge is essential to practical applications of ecological economics. Systems of problem solving develop greater complexity and higher costs over long periods. In time such systems either require increasing energy subsidies or they collapse. Diminishing returns to complexity in problem solving limited the abilities of earlier societies to respond sustainably to challenges, and will shape contemporary responses to global change.
