Sustainable Scale Levels

• Introduction to Scale Levels  Scale problems can arise at many different levels, and problems at one level can spill over into other levels
• Local Scale Levels  Local scale problems are as old as humans, but today's local scale problems are unprecedented in their seriousness and pervasiveness
• Regional Scale Levels  Regional scale problems are caused by the same dynamics as problems at the local level - use of non-renewable resources and overuse of renewable resources and sinks
• Global Scale Level  Solutions for alleviating local and regional scale problems (trade or migration) are unavailable at the global level. Global scale problems require global insititutions and solutions
