Pure unadulterated crap. Mars cannot support life. The average temperature of Mars is -65 Celsius (-85 Fahrenheit). How is that going to work out? There is no soil. what nonsense.
It ain't the kind of place to raise your kids.
Need Martian Saunas.
I Watched the movie, “The Martian”. What’s not to like?
Besides, I LOVE potatoes !
And you don't think the people doing the planning are aware of this and have figured out various solutions to it? What you could argue, though, is that the enclosed surface habitats or underground facilities they are proposing won't work for one reason or another.
In any case, what are you concerned about? Fungi can survive almost anywhere, maybe even Mars. :)
