I wonder if Obama would okay a fresh water pipeline delivering water from the fresh water lakes of Northern Canada? Nah...it might disrupt the migration of the caribou and destroy some geese habitat.
I have heard of one plan to bring water all the way from Alaska, through Canada, down through Idaho and into the area between the Sierra and the Rockies. I don't think it would ever be approved for environmental reasons, even though it is just moving water around.
