I have been thinking about this a bit lately, thought I would get your thoughts.
Let's assume that Mars has been terraformed to the point that you could live on the surface with no masks ect, but the weather for the next 50-100 years will be more extreme i.e. lots of cyclones, tornadoes, earthquakes ect. As for Earth, it is more or less like it is today, perhaps a bit more over crowded. You can travel between Earth and Mars, but it is very expensive, and took 3 months each way. This is the first wave of colonisation, only minimal infrastructure, government. No 'organised' marauders, just normal criminals.
The question is, would you move to Mars in this situation? Even with all the downsides, I still think that I would, because then I would BE ON MARS!
