This must be stopped! The carbon footprint of an exploding human body is enormous, not only does it release the carbon dioxide contained within the human, but it releases dead flesh and flings it all over the surrounding area. This necessitates a cleaning crew that further contributes to the carbon footprint of the suicidal explosion.

Car bombs are even worse, they use what little fossil fuel we have left just to make an explosion. Once again, the amount of gases released is enormous. And, as a general rule among the terrorists, the bigger the explosion (i.e. the more gases released), the better the car-bomb was.

Environmentalists, I call upon you all to assist America in our valiant effort to cease these polluting actions. Join the Army today!
