    train derailments would be noticed & probably cleaned up. No train derailment would do as much damage as the pipeline spills we've seen, like the 1979 Bemidji spill or the more recent Enbridge spill in MI.

    We may be stuck with limited use & train shipment tar sands from domestic sources, but we can't be forced to import and consume Alberta Tar Sands. We've made cutting use of dirty coal a priority in MN at least, and we can do the same with dirty oil sands (as the Canadians refer to it) or tar sands.

    We can use less, with fewer pipelines, and save more aquifers & wetlands from being spoiled for use by humans and wildlife, have fewer people killed in pipeline explosions. We can have less carbon dioxide & other greenhouse released in the atmosphere... it's possible, and it's the right thing to do to reduce the suffering of present day First Nations in Canada, and future generations globally!

      claims that train derailments are more frequent than pipeline spills, but release less oil per spill.

      I think that's actually true.  One problem with Enbridge, which I've seen in other pipeline mishaps, is that the pipeline operators didn't believe they really have a spill when their warning lights come on, so they keep pumping oil right out the damaged pipeline.

      Train derailments are painfully obvious, but can involve large quanitites on occasion.  I tracked ethanol tank car detailments for awhile, and there were multiple occasions of 5-10 tank cars (over 100,000 gallons) breaking open during a single derailment.   There are some youtube videos, the flames are spectacular.

       I doubt if Tar Sands would burst into flames.  However, rail lines usually follow bottom lands, so train derailments spilling Tar Sands could happen in and near rivers, too.

      Orly, it isn't evidence just because you downloaded it from the internet.
