Since it's beginning the earth's physical and atmospheric makeup
has been in a constant state of evolution. There have been ice ages and periods
of warming, as well periods of higher and/or lower oxygen content. There have
been volcano's and earthquakes(far exceeding anything we experience today),as
well asteroids impacting the earth, and this all has served to change earths
makeup allowing for the existence of differing life forms, and when they have
reached their potential, send them into extinction, paving the way for a species
more suitable for the changing environment. What we have over looked is that the
earth itself has a lifespan, does that mean the end of mankind as we know it
,opening the door for a more advanced species? Is earth just a starting point
for the human race, is man's future out amongst the stars living in self
sustainable colonies??? According to a study published in September, the earth
can support life for another 1.75 billion years providing nuclear holocaust, an
asteroid ,or some other disaster doesn't intervene. Stephen Hawkins(a noted
theoretical physicist) said in a a lecture on black holes for BBC such a
disaster is imminent ,that it is but a matter of time and we must tread lightly
for it will be at least a hundred years before we have advanced to such
capabilities technologically. Even if there appears no disasters the earth will
in the next 1.75 -3.25 billion years travel out of the solar systems habitable
zone into the hot zone. Is colonizing space the first stage to extinction of
mankind as we know it, allowing for a human species more suitable for life
amongst the cosmos???
