Population growth is vital for colonization of Mars. Earth will have to produce a lot of people to send to Mars in order to have the genetic diversity for self-sustaining populations on Mars. The people on Mars will then have to produce a lot of people to live and work there to generate growth and produce generations of humans who maintain The Light of Consciousness on Mars past any sort of otherwise human-extinction cataclysm back on Earth. This is also the only hope of eventually repopulating the Earth in this scenario.
