As my plane sat on the runway at the end of a long line waiting to take off from Newark Airport last week, I couldn't help but think how futile it seems to own a car that gets good gas mileage, to have installed new windows to better insulate my house and further cut down on energy usage, and to turn off the light in my hallway when I'm not there for five seconds, all the while fifty gigantic, energy-sucking jets sit idling on a runway waiting around for god-knows-what so they can take off.  The power of one = zero.  Change needs to come from above.  (Sorry if that sounds ridiculous and sensational; I couldn't think of a better way to write it.) #science
