Circa 2500 CE

It is year 2500 CE. Adam, a mountaineer has died of an accident, buried under an avalanche some 500 years ago. His body is brought to life by the miraculous advancement of the present-day medical science. It is a providence to be reborn but he is in a peculiar situation to face an altogether new world. He sadly recalls a world that was full of violence, misery, and suffering at the time of his death. It was a hell on earth then. He wonders if he was granted power to command all the resources on earth to transform the world from the state of being a hell to a paradise, would it be same as the one he is facing today? Or would he have done something different. Imagine, if you are in Adam's place, what would you do to change the world into a paradise on earth? Are you game to foretell a story of 500 years into the future, now?
