Resistance Radio - Charles Hall - 01/19/14

Charles Hall is a systems ecologist with strong interests in biophysical 
economics, and the relation of energy to society. Central to Hall's work is 
an understanding that the survival of all living creatures is limited by 
the concept of energy return on investment (EROI): that any living being or 
living society can survive only so long as they are capable of getting more 
net energy from any activity than they expend during the performance of 
that activity. He is the author or co-author of, among others, Energy and 
the Wealth of Nations,
