The native tribe protesting the pipeline said they have a "black snake prophecy" where a big black snake (ahem, kind of like a pipeline full of oil) will appear and poison the Earth. The environmentalists were referring to it a lot. I looked all over for Lakota religious beliefs, and could not find any reference to a black snake prophecy before the pipeline.
That’s because its bull$hit
That’s interesting.
I didn’t know that.
Thank-you for posting.
