So how many 4,700 year old trees do you own, or how many does Al Gore own, Parados? With a straight face, tell me that you have alot of trees that you have planted or that Al Gore has planted that will live more than a hundred years, or maybe in some cases a few hundred years. Big deal anyway, a hundred years or a few hundred years is miniscule in in the grand scheme of things.
And the big question is why should you get credit for something that will most assuredly die at some point and eventually cancel out the credit? Will your children or grandchildren have to pay your carbon debts for your dying trees?
P.S. I have seen bristlecone pine trees, have you? They are not that plentiful and the effort to get one to grow is not an easy or quick thing I would bet, and the likelihood that you could grow enough to amount to a hill of beans, carbon credit wise is preposterous. Besides, they only grow at high elevations.
