The bottom line is that it just doesn't matter what John Q Public thinks, the oil's gonna flow, and the cheapest mode of transportation will be employed no matter what the risk of environmental or human losses are.

We're back to "oil flows where the money goes" and as long as money trumps all else, there will be environmental and human losses. These will be written off as collateral damage in the name of progress, when in reality it's just greed.
