This episode of The Green Interview features Orri Vigfusson, an Icelandic businessman, environmentalist and "green capitalist" with an ambitious goal to save the dwindling North Atlantic salmon. To this end he has sought ownership of every commercial salmon-fishing license in order to retire them, and ultimately to close the entire commercial Atlantic salmon fishery. Over the past 17 years Vigfusson has systematically bought and shut down all but 15 per cent of the world’s commercial North Atlantic salmon fishing licenses. In this interview, he explains how these methods have won him the respect of the commercial salmon fisherman whose fishing licenses he is buying and "retiring."
