Just out of curiosity... are trees not the biggest carbon sink in Canada? And yet BC is cutting trees down in massive amounts, thereby increasing Canada's carbon footprint. Shouldn't the rest of Canada be up in arms at that provinces blatant disregard of global warming and refusing  to stop logging the forest? Shouldn't the rest of Canada stop allowing BC access to markets by refusing to allow lumber products to traverse the highways and railways? BC could ship the wood products by sea, but then I guess that would defeat the purpose of all their complains about stopping massive freighters and tankers into THEIR coastal waters.
The same arguments for stopping the production and transportation of Alberta's oil should  be used for stopping the pillaging, lumber production, and transportation of BC  forests. I guess Alberta should be charging BC a tariff to allow the movement across Alberta of BC forest products.
