It blows my mind that there is even a question of approving construction of the Keystone XL pipeline. The oil sands will be developed one way or another. The U.S. will keep using oil for decades. Doesn’t it make more sense to import oil from Canada than from repressive, autocratic nations like Venezuela and Saudi Arabia? (And for those who conflate being anti-pipeline with a belief that Peak Oil is around the corner — what better reason could there be to secure strategic supplies of crude?)
I might ad that the oilsands will be exploited and production will be increased if this pipeline is built or not. If the US doesn’t want the oil a pipeline will be built over the mountains to the west coast. The oil will be loaded into tankers and sold to the Chicoms.
