What if the World isn't a Perpetual Motion Machine of the Second Kind?

Quite simply, the world would run out of fuel (unless there's a big iron-eater and a hydrogen-shivering machine).
t doesn't help; for the world to live forever, every component must die. I only know of one reversible process. I don't mean a hypothetical cycle, but something that runs on its own without any intervention. That's the movement of electrons around the nucleus.
