How many people would it take to to run a self sufficient colony? I'd say it would take from 20-1,000,000 to live comfortably and still be a colony. But I want to know if it's possible with less than ten. Also, famous engineer and inventor Elon Musk says it's nearly impossible with less than a million people including children.
