Contamination of Mars

    I heard yesterday on Fox News that there is some concern with respect to the Rover mission to Mars. The idea is that the Rover equipment had not previously been sterilized and contains some microbes (bacteria, fungi, viruses, and microphage). Each of these organisms require water for their sustenance and growth. If Mars actually contains water, then we have contaminated that planet.
    So what? Here we have another example of environmental considerations out of control. If we bother to spend billions of dollars in nationbuilding on this planet, is there something basically wrong in carrying some of our natural resources (these microorganisms) to another planet?
    One of the bases for any kind of geographical exploration is the possibility of a human development in a new location. If human beings eventually want to go to Mars, how would they plan to sterilize themselves? A ridiculous notion.
