Default Why Colonize Space?

Today I was reading some opinions of people who believe that there is
no reason for humans to leave earth. Are all arguments for moving into
space and onto other bodies in space really that weak and irrelevant?


If you venture outside the Earth's atmosphere you lose the equivalent
of a full yard of solid lead radiation shielding (and no heavy element
pair formation), 14.7 psi. *Asstronaughts in Skulab, Mir, and ISS
FUBAR ahve a 95% incidence of radiation cataracts.

If you additionally venture outside the Earth's magnetosphere you get
cooked alive by solar storms and cosmic radiation.


Sounds almost as bad as Texas.
