If you went into the stock market and read up on where pipelines are being built, what is being shipped and to where you would realize that is not so. Anytime you buy any of these products anywhere you are part of that system. The USA is producing oil like a mad hatter. You decrease the internal demand so there is a glut of oil where do you think that extra oil is going to go? The USA alone has cut back on their needs for coal so where does the extra go, Bingo! China or Japan. If we completely stopped using oil there would be a glut and instead of our oil going to China thriugh Gateway, ( which I do not like) the Usa will sell them the extra oil they have, because they are more money hungry than we are.
Remember you are sitting in harms way right now because Japan used nuclear power instead of coal or gas power.
The problem is that it may not go through BC to get there but it will get there and you will still be recipient of the harm caused. In my thoughts, do not even think for a minute that because you are not buying Tarsands products that you are avoiding this as you are part of a market that you have no control of due to your refusal to stop using fossil products, and I mean any petroleum product.
