I meant that when you build the facility, it starts changing the planet so that the people living there become happy. Then if the player decides that those people are annoying, the player could increase the temperature and suck the air out making some vacuum-packed beef.

I have a question though. Not that it matters for game play or anything, and I won't use the "R" word, but how exactly would terraformers change the gravity of the planet?

That is quite simple. To decrease the gravity they have to put springs in every shoe on the planet. When increasing it they replace the springs with heavy weights.
