I’m readying Kim Stanley Robinson’s Mara Trilogy and it has rekindled my interest in the colonization of Mars and brings to light not only the physical challenges of terraforming a planet but also the political challenges of humans fighting over new land, resources and ideals on another planet.

Realistically any colonization of Mars would be carried out through “paraterraforming” aka dome cities or underground cities. And that is how colonization also starts in Robinson’s novels.

People who think it can never happen or is not possible or ignoring all the trends of human history where humans constantly expand and adapt their surrounding to themselves.
