P.S. - That shouldn't include banning discussion of castrophic events effecting Earth's evolutionary pathways, e.g. -
nearby supernovae and novae
dark clouds perturbing the Ort cloud
frequency of meteor impacts
(snip) None of which are anywhere nearly as threatening as human evolutionary "success" making the planet uninhabitable for any one of dozens of reasons- or we just kill everything including ourselves off outright. In terms of the length of a human lifespan, or even the lifespan of the human species, we really are in a relatively cozy place- as our presence here and now seems to prove. Based on our predisposition to eliminate competition through the killing of our own species- enhanced by technology, does anyone seriously expect there to be humans around 100,000 years from now? And if by chance we do manage to evolve beyond this primitive state before we self-destruct completely, one would hope that our technology would be capable of massive environmental manipulation (on the scale of a solar system, say). ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs
