Humans will not "live" anywhere in the solar system other than on the earth where we evolved. We may "survive" temporarily elsewhere, like on the ISS, but we will never "live" there. Earth is our only abode...

That will become a problem when an asteroid or supervolcano or any other unpreventable disaster comes along and makes Earth uninhabitable. We're going to have to find a way to live off of Earth if we want to continue to exist.

  The earth has been a long series of disaster movies. Massive extinctions after massive extinctions. Why do you think we as a species should be exempt? Are we that special?

    We have the capability to possibly avoid an extinction. Do you argue we should refrain from exercising it? That we should put forward anything less than our best effort at survival? Why? What do we gain by giving up without trying?

    You can't hate people for trying... to survive... That is literally what all life does.

Why? People have successfully adapted to all kinds of unexpected habitats here on Earth. Isn't your argument the same as someone from 70,000 years ago saying "Africa is our only abode"?

  No, because wherever you went 70k years ago there would be an atmosphere you could breath, H2O to drink and things you could eat. And wherever you landed you would still be shielded from solar radiation and enjoy 1G gravity...

Down votes? Really? Space is perfectly analogous to the ocean. We can put on a mask, fins and a SCUBA and swim about effortlessly. But do we "live" in the ocean? No, we only temporarily "survive" there due to technology. Evolutionarily we left the ocean behind billions of years ago. We can never again live in the ocean even if we build a colony on the bottom of the Mariana Trench. It will simply be a technological "survival" device and nothing more. And would anyone choose to explore the Trench with actual humans? Of course not. That's what robots are for. And the same goes for space...

  Because you clearly didn’t read the article, which covers how both Mars and Venus can be made to have stable habitable zones.
