Faced with the undeniable reality of “Hubbard’s Peak” in global conventional oil supplies, the world’s largest multinational energy corporations are now hell-bent on squeezing oil out of tar in northern Alberta, like junkies desperately conniving for one last giant fix in a futile attempt to quench America’s insatiable “addiction to oil” (described so eloquently by President George Bush II). Along the Athabasca River near Fort McMurray, a sub-arctic town almost 1,000 kilometres north of the U.S. border, tar literally seeps out of the riverbanks where Aboriginal peoples once used it to patch their birch-bark canoes. But most of the tar sands lie hidden below northern Alberta’s boreal forest, in an area larger than the state of Florida.
