I don't think living on Mars is a good or practical idea.

There is much focus on the physical possibility of living on Mars, yet little on the actual practicality of it. Life on mars in these conditions would be more basic, isolated and harsh than even living in Antarctica. Life would be so limited, basic and restricted that it would be barely life at all. Who would actually want to live like that? And if they did they could easily do that on earth anyway. I think it will be a place for the occasional expedition of scientists and that is it. I don't think we will ever colonise it.
