There are plenty of reasons to be against the Keystone XL pipeline. Environmentalists recognize it as the ultimate "bonfire of the vanities" -- planet-wide carbon bonfires. Here is another reason, perhaps the best reason of all: It doesn't do us any good. China, yes. The Koch Brothers (who own the refining capacity that would be used), yes. Us, no.
Although he has struggled with the paradox of reducing carbon pollution while promoting a dirty "all of the above" energy policy, Obama already has more than enough evidence to reject this pipeline based solely on its effect on climate disruption. But even though this debate has centered on climate, that is only part of what's at stake.
