Issues to surviving on Mars
Many things have to all come together to allow people to land and live on Mars.
The most doable certainly from SpaceX point of view is the spaceship to get humans to Mars (see BFS) yet supporting life and designing all the equipment to achieve this goal is formidable especially if a mid 2020s human landing is to be attempted. (See living off the Land)

Conclusions (from Wait but Why)
If Mars were a place on Earth, no one would ever want to go there. But in a discussion of inhabiting non-Earth planets, all of which are a total nightmare to live on, the prospect of moving to Mars sounds oddly okay.
Mars is basically a colder Antarctica that looks like the Arizona desert with air you can’t breathe and a sun that radiates you to death if you’re exposed to it for long. Every part of Mars is dramatically less livable than the least livable place on Earth. But the conditions are reasonable enough that with a man-made “hab” to live in, a little greenhouse garden, and a good enough spacesuit, you could actually exist on Mars without dying.
