I tend to follow the non-contamination camp as a matter of probabilities: it is unlikely in the extremis that biological life evolved elsewhere will even remotely resemble our "baseline" biochemistry; and almost certainly not at the gross complication of viral-analog or bacteria-analog organisms. I suspect it likely that alien organisms will be chemically toxic to each other, but non-pathological -- no "Andomeda Strains". While this is good news for the disease fighters, its bad news for "live off the land" advocates: what you pick may well be poison and kill you, or maybe not; but in any event you'll find absolutely no nutritional value in that pretty piece of blue "fruit".

It is the development and construction of our infrastructure, and the subsequent terraforming activities that will destroy Mars bugs -- mechanically, physically, with bulldozers and dynamite.
