By rejecting the Keystone pipeline, the Obama Administration has exposed North America to more environmental damage, not less. The product that would have been shipped by an environmentally friendly pipeline will now be moved by rail, environmentally much more threatening.
Typical environmentalist policy -- destroy the environment while claiming to help the environment. Even Heather Ross, an extreme environmental activist, made exactly this point in her book "Green Gone Wrong," in which she thoroughly documents how environmental activists have, on balance, damaged the environment by their activist policies.
Results don't matter to environmentalists. The only thing that matters to these folks and to Obama is the narrative, even if that narrative is a false narrative.
