Space and survival : ウィキペディア英語版 | Space and survival
Space and survival refers to a position stating that the long-term survival of the human species and civilization requires proper use of the resources of outer space, and in particular space colonization and space science, as failing to do so, it could lead to human extinction scenarios. A related observation is the limited time and resources thought by some〔 (UK title: Our Final Century)〕 to be available for the colonization of space. Various scenarios regarding human survival have been discussed in science as well as popular culture. The article will cover speculations about how mankind can survive post future catastrophic events in the evolution of the solar system as well as the factors that could help or hinder this survival. The earliest appearance of a connection between space exploration and human survival goes back to Louis J. Halle’s 1980 article in ''Foreign Affairs'', in which he stated colonization of space will keep humanity safe should global nuclear warfare occur. This continued to grow as an idea, getting more attention in recent years as technology development makes cheap space travel more feasible. ==Risk to humanity== With space and human survival comes risk to the human species. A severe event in the future is one that could cause human extinction which is also known as an existential risk. Humanity’s long track record of surviving natural hazards suggests that, measured on a timescale of a couple of centuries, the existential risk posed by such hazards is rather small. Nevertheless researchers have experienced an obstacle in studying human extinction as humanity has actually never been diminished before. Although this does not mean that it will not be in the future with natural existential scenarios such as: Meteor impact and large-scale volcanism; and anthropogenic-natural hybrid events like global warming and catastrophic climate change.
