I was reading the global warming thread and my wind wandered onto this interesting tangent. What would happen to the world if we knew beyond a shadow of a doubt that in 100 years all life on Earth would be destroyed? For instance, the sun is going to explode or something - so moving society to the moon or a space station is not an option. Imagine the ramifications! What would governments do? What would corporations do? What would wealthy individuals do? Perhaps having children would be outlawed worldwide. Forced vascectomies for all! Maybe in the short term, things would actually get better? After all, there's no need to stockpile wealth since there will be no one to pass it on to. So it seems a lot more wealth would be spread to the third world nations and the have-nots of society. But at what point would the social order collapse? How would you live your life differently? How long until the economy collapses and people stop working? People still need to eat, so I imagine they still need to work, except for the wealthy who have enough to last until they die. So many interesting possibilities, I'd love to hear your speculations. Also, is there a movie/book with this premise? Seems like it could be a good scifi story.
