Rerouting would be better than nothing - and far better than a tragedy at Standing Rock - it would give you a much needed "win" !
Much has been accomplished already at your encampment.
Many steps have already been put in place over the ten years I have been an environmental blogger. The World Bank commissioned their "Turn Down the Heat", the International Energy Agency reversed their denialist stance and calls for as rapid as possible weaning from fossil fuels - the Vatican and Pope Francis produced an entire encyclical "Laudato Si", calling for the same and much more - humanism.
And the rerouting is possible - even now.
I reminded Barack Obama of the movie "Midway", where Admiral Bull Halsey says to his new commander:
" When you are in command - command ! "
Here in Canada we have pipelines being approved which make no environmental sense, but apparently they make political sense at this time - when most people are still just waking up to the reality of a world without clean water, air, oceans, and soil being washed into the sea.
This war will not be won in a day. I shudder to think how close we will come to disaster.
Live to fight another day - if possible.
