An honest study of Keystone and GW would be that it would be worse if we did not build the pipeline since the oil would have to be transported to the West coast then to China to fuel their industrial expansion.
The logic escapes these bastards. You have a million barrels of oil flowing in a pipeline over hundreds of miles. Or, you have a million barrels of oil being transported by rail and trucks over hundreds of miles. Which is the greater contributor to “global warming?”
