This makes no sense from the enviro-mag Grist:
RT @carbonhound: US approves Canadian pipeline to deliver oil from tar sands. Not renewable but not from the middle east http://bit.ly/wC4Cq
The amount of carbon it takes to get oil out of tar sands is much, much higher than getting oil out of the ground in the Middle East. If we’re going to use oil, shouldn’t we want to get oil from where the oil is easiest to get, from an environmental standpoint at least?
