Mine the asteroid field for resources. At some point, if humans don't destroy themselves, we will need to find a world to expand to. Our technology and understanding of the universe just seem too limited at this point in our evolution.

using current technology, it would be easier to mine on Mars (or any sizeable planetary body) than it would to try and mine an asteroid. Right now, to mine or drill on Earth we need to be able to lubricate the drill bit, with water usually, which would be impossible on an airless asteroid. Also, there's the issue of no atmosphere to dissipate the heat generated by the friction of the drilling/mining. And then there's the issue of the debris that would inevitably be floating around our drill site forever because of the microgravity environment of an asteroid.
On Mars, there's water, and sufficient gravity to keep the dust down, as it were, and a large enough planetary body/atmosphere to dissipate the heat.
The gravity would also be helpful when it comes to refining, as we don't know how we'd separate the metals we want from the raw ore in a zero-gravity environment (iron, aluminum, titanium, etc).
And Mars does have some other desirable metals/minerals, such as rare earth metals, magnesium, selenium, sulfur, etc.
