Description:The traditional approach for diagnosing and managing environmental change has been to reduce complexity in an attempt to identify simple relationships. Such a view presupposes that a problem setting can be clearly bounded and dealt with through appropriate remedial action. It tends to reject the complex real world as a diagnostic force because of its inherent unpredictability.

This conveys how existing intellectual resources can be exploited to explore environmental decision issues without resorting to such devices as ''meta-methods'' or ''meta-disciplines''.
