stop using these words:
they mess up your mind

MISSION
why "mission?" Only Government lap dogs are sent on "missions." Real people take trips or make voyages.

TERRAFORMING
Fuhgeddaboudit. This is the height of arrogance: the assumption that one may go ahead and modify the climate of an entire planet regardless of whether the residents like it or not. Or, maybe the assumption here is that everyone will surely like it. I've never seen a proposal for getting every last person's permission, however.
To pollute another person's property is a crime - vandalism at minimum. Terraforming - changing someone's climate against his will - is pollution, vandalism and worse. If you try to terraform Mars while I am living on it, I will kill you. And you'll deserve it.

WE
don't presume to speak for others. There is no "we" unless you are the bona-fide boss-unit of an already-existing group of people, and then your statement only concerns them (and then only if they continue to take your orders). This jazz about where "We" are going and what "We" should do must stop. Speak only for yourself.
