Scenarios have four dimensions  
(i) ‘Status Quo’; which assumes that the present will continue into the future. 
(ii) ‘Collapse’; which results when the system cannot sustain continued growth, or when the contradictions of the status quo lead to an internal decay or crash.
(iii) ‘Steady State’; which is based upon a return to some previous time, either imagined or real, that was perhaps quieter, slower or generally less commercial, industrialised or densely populated.
(iv) ‘Transformation’; which presumes some fundamental change that may be spiritual, technological, political or economic.
