Probably a dumb question but I feel like it's the best place to ask, what are realistically the reasons to colonize Mars ?
Ressources, overpopulation and this kinf of stuff sounds like problem that can be solved with cheaper "earth" solution considering the absurd amount of time, money and ressources needed to start a colony on Mars. I guess the Europeens were facing similar cost when colonizing America, but I still wonder if the need for Mars colonization is fundamentally realistic or not, on a socio-economic point of view ?
