OK so I just talk to my boyfriend about 100 the show and if you haven't seen it I said go check it out but it's about the world ending and people who went up to space to save some of the population and years later they're running out of resources and shit and they go back down to earth to see if it's habitable now right in the way end it was the way the world and it was so realistic and I think they did destroy the world twice like come on now but the question is If you had to guess realistic or not how will the world end
