This video is from the same people that brought you the Chickenomics video I showed last week, but don't hold that against it! This is much better. 

I remember reading a lot about space colonies not long after this video was made. The science is completely sound, but alas we humans do not do well in low gravity, in fact it destroys the bones. Solar radiation is a big hazard. But that is not the point of this dystopian short video. 

Is the future depicted in the video in our future? To a degree it already is.
