I know this sounds somewhat callous, but whale hunting by native tribes has been going on for at least a couple hundred years. Entire societies and economies have been built around this industry in the past. Is it no different than hunting deer or raising cows for slaughter? My only philosophy to any hunting, whale or otherwise, is to use as much of what is killed as possible.
