If you're not sure how big your carbon footprint is (just look at the size of your Con Ed bill for July) or you're not sure if you should give up meat to ease up the burden on our environment (just read today's Times), then you can always count on Australian schoolkids to help you make your decision. A bunch of ingenious folks from Oz have devised a game, aptly named Planet Slayer, that would make an insurance adjuster blush: calculate when you "should" expire if you really want to help out humanity. I know, you're an awesome foozball player and have too many Facebook friends to just die, but some people think you're just a drain on precious resources, so give it a spin!
