With Air Canada’s announcement today of staff layoffs and route reductions due to escalating fuel costs, North America’s dependency on oil and gas continues to be underscored. On CBC Radio this morning one analyst said, “it impacts all our stuff”. In other words anything to do with “stuff” is reeling from higher barrel costs - meaning everything. The interview went on to touch on what it that could possibly mean in the longer term as fuel costs become a profound economic and social culture disruption - collapse of suburbs, fewer trips but of longer duration, living “smaller” rising food costs etc… When historians look at tipping points in the 21st century this will obviously be one and interesting to ponder how it will impact how we will live and the decisions we make.
