Three propositions: (1) Canadian cities are located, not on Baffin Island, but in the middle of the country's most fertile farmlands.  (2) For both economic and environmental reasons, Canadians want to preserve those farmlands.  (3) Governments and private enterprise have encouraged Canadians to believe that they are entitled to a low-rise, detached home with a garden, within reasonable distance of their place of work.  

These three things cannot be reconciled, and sooner or later (2) or (3) or both will have to go.
