Opponents, on the other hand, will vehemently argue against it. Some for scientific reasons (we should study Mars before we modify it), others for ethical ones.

By Sean McMahon
Mars has been a wandering star, a vengeful God, and latterly a storied world of shifting greenery, huge canals, carved faces, pyramids, aliens, and warrior princesses.
