Hey, you little snots, why not go to New York and stick this on a fire engine? They burn LOTS of gas. Be sure to explain it to the firefighters.

When you get out of intensive care, I'll be waiting. No, not with the famous 300-lb. dead sturgeon--too much work, and I tend to tear muscles beating people into insensibility with it. No, I've got something better: a little device I call the Karmic Bomb.

When it goes off in your face, you are not injured, but immediately tranferred into an alternate reality, where the world is EXACTLY like you deserve. You'll find yourself living in a rude hut, pounding roots for food, watching flies crawling on your kids' eyes, and parasites eating their way out of your skin. No oil will be burning anywhere within a hundred miles of you, and the air will be clean and fresh. Except for the stench of rot.

Oh wait--that's not a parallel universe. That's the lifestyle of millions of people here and now in the Third World--you know, the ones people just like you at the Earth Summit were complaining might wreck everything by getting electricity and plumbing. The ones living the life you would wish on all of us.

(I tacked a version of this onto their comment line.)
