Its been reported that Chinese industrial pollution is drifting and may be blowing in and around the west coast.
The tar sands are going to go somewhere to be refined, that is a fact.
Its also been reported that we have much more efficient ( clean) facilities to refine it. If it makes its way to china, it will be refined less efficiently ( dirtier) and wind up in the air regardless, will add more net pollution and may in fact blow over us anyway to boot.
In addition theres the transportation issue; if we don't do the pipeline, it will be railed to Canadas west coast for transshipment to china, and/or railed here, a pipeline is and always has been the cleanest least riskier avenue of transportation.
So, if the goal is to prevent pollution, contamination via spillage etc. and add some jobs, it appears to me , refining it here via pipeline delivery is a win win win.
(500k jobs is ridiculous, I think its 20-40K(?)).
Hmm. I wonder who it is that might stand to make a lot of money should that go by rail.
No surprise there. Warren Buffett, a big Obama supporter.
