When I talk about terraforming Mars, I'm more thinking about in enclosed, man-made ecosystems. Not so much altering the entire planet's atmosphere.
Terraforming was probably the wrong word to use in that context, although you would need to establish such a ridiculous amount of arable land in order to sustain the population, that calling it terraforming wouldn't be so far off the mark - even if it was in an enclosed system.
