Redundant Canadian Tar Sands Crude Pipelines and Larger Northern Brains Perfidy?

Building an ecospherically invasive, displacing pipeline from Canada across the U.S.A. in order that Tar Sands Oil can be refined and sold to Brazil as gasoline seems outright dumb. A much shorter, entirely Canadian pipeline to carry Tar Sands oil from Alberta Canada to saltwater in a British Columbia (well, a few miles short on a river) is already going ahead. One must wonder how stupid U.S. politicians are to let that sort of ecospherically corrosive project be considered at all.

Apparently U.S. economic and energy leadership is just moribund-what ever happened to President Obama's state of the art 'clean coal' vision? Can't some sort of high tech electric car power line in highway for smaller, faster cheaper battery recharging be built instead? The again, why not invest in the hydrogen infrastructure at last?

These Canadians as northerners probably have larger visual cortexes and eyes than southerners in the 48 states. They may be attempting to build a best case for them pipeline infrastructure for exporting oil and gas to foreign destinations. While the Canadians are America's brothers in revolution (well, almost, it was only a fluke of fate that Tory's led Canada to be on Britain's side instead of ours), and we should be concerned to help them maximize their economic potential, it would be an abrogation of the 'tough love' axiom to let them do harm to the ecosphere of Canada and the U.S.A. by constructing a superfluous pipeline. We already know that Hugo Chavez and Venezuela's radical force of the left and are investing in new exploration and sometime will get around to cracking crude for point sale of petroleum to South America while the Tar Sands oil is more likely to find better sales prospects in China-a nation that is the world's largest greenhouse gas emitter and doesn't mind some Tar Sands crude.
