Colonization

Tierny, John. "A survival imperative for space colonization" July 17 2007. March 27 2009. http://www.nytimes.com/2007/07/17/science/17tier.html

The scientist from this article Dr. Gott predicted in 1993 that humanity would last atleast another 5100 years. and now he says that to ensure our long-term survival we need to get a colony started on mars within the next 46 years. this article talks about scientific stuff and previous predictions made by other scientist's. and why they agree or disagree with their arguments about humanity's life span.
I personally dont know much about science and our earth. but i do not believe that starting a new colony on mars will do anything for us..
