> I never understood why colonizing Mars is needed.
For the same reason in tech we have backup servers, HA clustering, disaster recovery sites, etc. A bit of redundancy helps in case something goes wrong.
> Earth would be more "hospitable" to life than any other planet in our solar system
Currently, sure. But other planets, especially mars, can be terraformed and made habitable one day ( it would take hundreds or thousands of years ).
> It's much easier to build and maintain a bio-dome in the Sahara desert, Arctic region, Cheyenne mountains or underwater than on Mars.
Sure but a terraformed mars can support more life eventually.
> Earth at it's worst is much better than anywhere else in our solar system.
The same goes for siberia, alaska, canada, etc. There are far more hospitable places to live on earth than those places. But people still explored, migrated and settled. It's human nature.
Edit: Not sure why I'm being downvoted but if anyone is interested in a talk of mars colonization, here is an interesting TED talk.
