Do you think people can really live on Mars?

No, of course not. Hollywood wants us to think so, but sadly, or gladly, this is not and never will be possible.
Mars is a poisonous planet with no liquid water. It is hundreds of degrees below zero at night. You cannot breath the air. You cannot grow food. You cannot make goods there. Everything would have to be imported from Earth at great expense just so a few nuts can go and live.
It’s not happening.
