A clever campaign video, this. Bristol Bay, Pebble Mine, widespread devastation – these are big concepts; too big, perhaps, for the casual viewer to get his head around.
So narrow it right down and focus on the problem in microcosm – a test drilling hole, a small platform and just a few strands of discoloured water trickling across the vast landscape.
And trust your viewers’ imaginations to do all the extrapolation needed.
They won’t let you down.
