Uses of Space Colonization
Extinction can be prevented by improving the physical barrier or increasing the mean distance between people and the potential extinction event. For example, people may survive imminent explosions by being in a bunker or evacuating. Pandemics are controlled by putting exposed people in quarantine and moving healthy people away. The human lineage of genus Homo has reduced from several species co-existing on Earth to just one — all others went extinct before the end of the last Ice age. This illustrates that Homo sapiens is not immune to planetary disaster and that human survival may be better assured through the colonization of space.

Famous quotes containing the word space:
“No being exists or can exist which is not related to space in some way. God is everywhere, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an effect arising from the first existence of being, because when any being is postulated, space is postulated.”
—Isaac Newton (1642–1727)
