Microbes could help future Mars explorers make rocket fuel and oxygen on the Red Planet

Why go to Mars via other than robots? There's neither life nor resources there to exploit. And what about food, shelter, water and heating for any Earth visitors/colonists? Other than full time government funded employment for Earth bound scientific types and corporations, humans going to Mars seems "a very hard road to travel".

If Mars was once a lush, green and blue planet like Earth, then there very well may be plenty of resources there to exploit. And of course, there's that whole extinction thing in a billion years or so (if not sooner).

I seem to recall that the longest lived hominin species was H. Ergaster/Erectus which was about 2 million years. Given the technologies and mental disposition of H. Sapiens, we don't have the luxury of such a time scale. H. Sapiens, or an evolving sub species, does need to leave Earth in about a billion years, preferably much sooner, (i.e. prior to the forecasted natural environmental changes). IMO, Mars just ain't the long term place to go, practice and learning notwithstanding.
