A reading of The Value of Biosphere Earth, part 4: "Earth vs. The Universe" by researcher/author, Chris Searles. In two short paragraphs, and with two simple graphics, Chris dismantles the idea that science fiction is real. In other words, We cannot "live" in any normal sense of the word, on another planet for the foreseeable future. Those planets with life-potential are so far away it will take thousands to millions of years to actually get the first probes there, with current technology. As far as Mars goes: it will be robots, not humans, who go to Mars for the foreseeable future. Anything else is just inhumane.

This series seeks to connect people of all backgrounds to a better understanding of what Earth's life-support system is to us today -- Earth's planetary-scale composition of diverse-life and living ecosystems, Earth's biosphere. The research in this series then goes further to show how "Biosphere Earth"'s quality and integrity are Civilization's #1 priority. In this episode, author Chris Searles, synopsizes how Earth's biosphere compares that of +4,500 other planets scoped by NASA. Scroll down for program and citations.
