Various complex dynamics in ecologic-economic systems are presented with an emphasis upon models of global warming and fishery dynamics. Chaotic and catastrophic dynamic patterns are shown to be possible, along with amplified oscillations due to these non-linear interactions in the combined interactions of human economic decisionmaking with ecological dynamics are identified and discussed. Implications for policy are examined with strong recommendations for greater emphasis in particular upon the precautionary principle to avoid catastrophic collapses beyond critical thresholds and the scale-matching principle to ensure that efforts to manage complex non-linear dynamics are directed at the appropriate levels of ecologic-economic interaction.
