It is not only the 100 years of projected levels of extraction from the oil sands, but we are also looking at coal bed methane which is just starting and the projection is 635 years in that industry and another 800 years in coal.
On projette d'extraire des sables bitumineux pendant 100 ans, mais aussi du méthane de houille, dont l'exploitation ne fait que commencer, pendant 635 ans, et du charbon, pendant 800 ans.
