I'd highly recommend reading the referenced Mars Trilogy. The debate has some more detail in the words of the characters (though the summary here gets the major points of the "Reds"). What's missing here but present in the series is the counterpoint. For purposes of profit and self preservation, terraforming is all but inevitable. A more useful debate is about how it should happen if you want to preserve some of the Martian natural beauty.
