I'm sitting here in the dim light of a CFL bulb, using my little laptop, sweating in the July heat because air conditioning is a giant energy-suck and wondering if any personal effort to reduce carbon emissions is worthwhile, when the Large Hadron Collider uses a gazillion bazillion teramegaelephantine watts of power.

I also get kind of bummed out when I watch NASA launch a space shuttle. Really, what is the point of me driving a tiny ultralow emission car?
