add over fishing ,commercial, sports ,aboriginal sectors , ocean, river, stream temperatures , stream levels dropping , mining ,logging , incidence like mount polley which left Hazeltine creek, polley lake and Quesnel lake NO chance at recovery , sediment with HIGH levels of copper, iron, manganese, arsenic, silver, selenium and vanadium. for what ever reason the seal population on the north coast hasn't exploded like it has on the south coast , but the northern transient pods (biggs) are heathy comparatively, they also target seals more so than the salmon reliant southern resident orca's. which for anybody who doesn't know or care (avg Albertan) isn't doing very good. but hey 440 more ships annually (880 return trips) shouldn't be a problem, because adding MORE ship traffic is totally the answer , after all they are just killer whales and salmon , unless its a mad cow disease, it doesn't matter. how did we as a country do without exporting DIRTY oil for so long, and now apparently we cant move forward without this imposition????????????
