other ( explain)
The tar sands are a GIGANTIC region...141,000 square kilometres...not one tiny hole in the ground.
Plus, the pipeline would take oil from the pipeline, not the other way around. How is it remotely possible that blowing up the pipeline (which I assume will originate from just one small section of the tar sands) could ruin the entire tar sands?
I do not see how any one group could ruin the tar sands no matter what they did to it.
Now, if you are talking about some gigantic oil spill from the pipeline - fine.
But, imo, there is no remote way that a terrorist group could destroy the tar sands by doing something/anything to the Keystone pipeline.
