Richard Greene is wrong when he says that environmentalists opposing the pipeline are ignoring science. His argument is based on the old tired statement that “the tar sands oil is going to be used anyway” and the pipeline is an environmentally safer way to transport it than shipping it by train or tanker.
But it takes human planning to bring the tar sands oil out of ground, and we can and should prevent that from happening by any means. It’s not the manner of transmission but the tar sands oil itself that is way more toxic to the atmosphere than conventional oil.
Climate scientists such as James Hansen have predicted Keystone would be “game over” for reversing the effects of excess greenhouse gases on changing the climate.
Much of this tar sands oil would be exported to China anyway.
So Keystone XL would not reduce our dependence on foreign oil, and there are other desperately needed infrastructure projects that can employ as many workers without the toxic side effects of tar sands oil.
President Obama should stop any avenue to bring that oil into the United States.
