PDQ and Bert,

We are not talking about any oil but the dirtiest of all, the tar sands.
Why transport that at all? The U.S. doesn't use it, it gets exported and the energy companies get rich. In the meantime, it if is the safest form of transport, we are in big trouble. It's not about shipping oil that is in US reserves. It's about transporting oil across the U.S. which is not safe at all regardless of the safety of other transport means.

If they don't build a pipeline, than tar sands oil will remain in the ground where it belongs. If you think that pipelines won't be compromised then you are truly naive and have bought the oil industry propaganda. I repeat, "game over!"

The pollution from exhaust pipes and chimneys are only a small portion of the problem unless you ignore what happened in the Gulf Coast. Don't think for a moment that this pipeline will be maintained without spillage. Safety controls have never really been in place by the major oil companies in the US.
