Idea that long term human presence requires to be spacefaring

Space and survival is the idea that the long term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be limited due to the decreasing amount of surplus resources that will be available over time as a result of an ever growing population. The earliest appearance of a connection between space exploration and human survival appears in Louis J. Halle, Jr.'s 1980 article in Foreign Affairs, in which he stated colonization of space will keep humanity safe should global nuclear warfare occur. This idea has received more attention in recent years as advancing technology in the form of reusable launch vehicles and combination launch systems make affordable space travel more feasible.

A severe future event that could cause human extinction is known as an existential risk to humanity. According to the Future of Humanity Institute, "humanity's long track record of surviving natural hazards suggests that, measured on a timescale of a few centuries, the existential risk posed by such hazards is rather small." Nevertheless, studies about human extinction have never been thoroughly conducted, although it's foreseen that future anthropogenic events, like global warming and catastrophic climate change, or even global nuclear warfare, are more likely to lead to existential risks, instead of natural disasters such as meteor impacts or large scale volcanism.

The observation and study of space protects Earth, as space hazards can be seen in advance and, if discovered early enough, acted against.

Near Earth objects (NEOs) are asteroids, comets and large meteoroids that come close to or collide with Earth. Spaceguard is the collective name for some of the efforts to discover and study NEOs, though these efforts are not sufficiently funded.

Some more contemporary reasons for space as a solution to survival have been identified as imperialist reasoning for space exploration, only relocating collective shortcomings and not solving them.
