Yeah - I'm a bit alarmed on how many people can't think out of the blue ball (sorry for the pun) - there are many many ways we can build our own environments as needed about anywhere in space given some resources and energy. Also while Earth is pretty ideal, it is not perfect - for example some places in Japan can be regularly hit by earthquakes, tsunami, flooding, Typhoons and even volcanic eruptions! If done right, habitats could be much better than planetary environments.
