History Main / HomeworldEvacuation

* ''Series/EvacuationEarth'' has as its premise a wayward neutron star heading towards Earth and attempts to build a GenerationShip to take 250,000 people to Barnard's Star.

* This happened 1000 years ago in ''VideoGame/SolastaCrownOfTheMagister''. The humans of Tirmar left their world to enter the world of Solasta. They were fleeing their sworn enemies, [[{{Lizardfolk}} the Soraks]], who unfortunately, have followed them in their new world .

** In "A Hundred Days" the [=SGC=] tries to evacuate the inhabitants of a planet that was about to be bombarded by a massive meteor show.

** The cancelled and non-canon novel ''Literature/AlienExodus'' from ''Creator/RobertJSawyer'', would revealed on how the humanity fled from a computer-dominated future Earth, in the 25th century, and transported ALongTimeAgoInAGalaxyFarFarAway when your ship fell into a wormhole.

* One short story involves humanity migrating from the Earth to the Moon so they can [[ColonyDrop throw the Earth]] at hostile aliens.

* In ''Literature/ForWeAreMany'', the Bobs learn that the [[PlanetLooters Others]] are on their way to Delta Pavonis, and they tend to wipe out any species that may resist their looting. As such, they send two colony ships to Delta Pavonis IV, so that they can save at least some members of a local sentient race, whom they dub the Pav. The Pav are roughly at the level of the early 20th century and are hardly in a position to resist the Others. The Bobs manage to save about 20,000 out of over a billion. Then, in ''Literature/AllTheseWorlds'', [[spoiler:the Others are heading for Earth with an even bigger fleet. Luckily, two Bobs have managed to get their hands on a derelict Other transport ship, which has enough internal space for ''fifty'' times as many people as there are left on Earth. The problem is that, by the time the transport arrives into Earth orbit, only 6 million stasis pods have been built, and the Others are already here. Riker then has an epiphany and decides to load the remaining 8 million without putting them to sleep. The evacuation is partly successful - a stray shot from an Other "Death Asteroid" wipes out the Cuban enclave, killing all 150,000 people there. In the end, the Bobs win the battle, so the still awake humans are brought back to Earth, so that the Bobs can finish building enough pods for everyone to evacuate (Earth's environment is rapidly moving into a nuclear winter).]]
* Happens in Creator/StephenBaxter's ''Literature/{{Moonseed}}'' when runaway geological activity [[spoiler: is turning Earth inhabitable and mankind, or better said what remains of it after massive worldwide earthquakes and volcanism, moves to a Moon that has gotten a breathable atmosphere]].

* In ''VideoGame/ChaosRingsIII'', the Satellite Base Theia was originally part of a fleet of ships meant to evacuate as many humans as possible when a PlanetEater made its way to Marble Blue. Due to [[spoiler:the Entity deciding to lay its egg on Theia instead since the appearance of the Incarnati made Marble Blue too dangerous]], Theia was unable to leave Marble Blue's orbit. Unable to fulfill its original purpose of finding a new home for the humans onboard, Theia instead became that home. Chancellor Steiner reveals that they lost contact with the rest of the fleet a long time ago. For all she or anyone else knows, the people of Theia are all that remains of humanity.

* Franchise/DragonBall:

* From ''Anime/Gundam00AWakeningOfTheTrailblazer'', [[spoiler:the [[StarfishAliens ELS]] are eventually revealed to be InvadingRefugees, having been forced to abandon their old homeworld after it was reduced to a sharred husk following the death of their sun]].
* Before ''Gundam 00'', there was ''Anime/MobileSuitGundamCharsCounterattack'', where Char plotted to send the asteroid Axis to Earth to force mankind into space and evolve into the Newtypes he thinks they'll become.

** In ''Anime/DragonBallZ'', when Namek is set to explode by one of Freeza's attacks, a wish is made on the Namekian Dragon Balls to save their lives by evacuating all the Namekians to Earth. They reside on Earth until they can summon Porunga again, then have him transport the Namekians to the newly discovered New Namek. [[ContrivedCoincidence Which looks just like the old Namek]].
** In ''Anime/DragonBallGT'', when Earth is set to explode by the effect of the Black Star Dragon Balls, everyone is evacuated to the nearby planet Plant, which had just been placed on Earth's orbit. They use Porunga later to restore the Earth.

* ''Anime/CowboyBebop'': The Hyperspace Gate explosion fifty years prior to the events of the series [[DetonationMoon blew the moon to pieces]], and the chunks are ''still'' falling on Earth about as regularly as rain. It's basically a giant slum, and the most well-developed planet is Mars.

* From ''Anime/Gundam00AWakeningOfTheTrailblazer'', [[spoiler:the [[StarfishAliens ELS]] are eventually revealed to be InvadingRefugees, having been forced to abandon their old homeworld after it was reduced to a sharred husk following the death of their sun]].
* Before ''Gundam 00'', there was ''Anime/MobileSuitGundamCharsCounterattack'', where Char plotted to send the asteroid Axis to Earth to force mankind into space and evolve into the Newtypes he thinks they'll become.

* Earth in ''Nova Praxis'' had to be abandoned after a [[GreyGoo nanotech weapon]] turned out to not be as easy to deactivate as its designers thought it would be.

[[folder:Anime and Manga]]

* Earth, or Lost Jerusalem as it's called, is referred to often in ''VideoGame/{{Xenosaga}}''. Humans had to leave it because of a mysterious space-time disturbance. Its location has been long lost. At the end of the third game [[spoiler:a chunk of the party goes off searching for it, and we're left wanting another sequel.]]
* The [[AllThereInTheManual backstory]] for ''VideoGame/{{Xenogears}}'', is similar. Humans left Earth in AD 2510 due to a space-time anomaly. The only reference to Earth in the game, though, is in the intro, and it is called "the main planet."
* ''VideoGame/XenobladeChroniclesX'' starts with humanity flying off on massive Ark Ships to escape an alien war. Very few of them even make it out of Earth's atmosphere before being shot down by the alien forces. The game proper follows one of the surviving ships in the months after it's begun colonizing a new planet.

* ''Series/TheTwilightZone1959'': A small-scale example occurs in "[[Recap/TheTwilightZoneS1E14ThirdFromTheSun Third from the Sun]]" when two scientists and their families steal an experimental spacecraft to flee their home world before a nuclear war that will probably kill everyone else on the planet.
* ''Series/TheTwilightZone1985'': In "Voices in the Earth", most of humanity evacuated the dying Earth 1,000 years earlier after it became [[PollutedWasteland incapable of supporting life]].

* ''Literature/TheWarOfTheWorlds1898'' may be the UrExample: the Martians attempt to evacuate Mars ''en masse'' using fairly primitive space travel due to their planet being in the process of drying up. Unfortunately for humanity, they've chosen Earth as their backup (it is implied that they ''can't'' reach any other suitable planet, or else they might not have chosen the Earth, whose heavier gravity is uncomfortable for them).

* In ''Literature/LastAndFirstMen'' the Fifth Men migrate to Venus when the Moon (destabilized millions of years earlier in the Martian/Second Men war) starts to crash into the Earth. And the eighth men design the ninth to colonize Neptune when the sun expands to cover the Inner System. But eventually, the sun goes nova too quickly for the Eighteenth Men to devise a means of escaping to another system, though they do manage to send out "seeds" of life that might eventually evolve into new humans.

* ''Literature/TheWarOfTheWorlds'' by Creator/HGWells may be the UrExample: the Martians attempt to evacuate Mars ''en masse'' using fairly primitive space travel due to their planet being in the process of drying up. Unfortunately for humanity, they've chosen Earth as their backup (it is implied that they ''can't'' reach any other suitable planet, or else they might not have chosen the Earth, whose heavier gravity is uncomfortable for them).

* ''Franchise/TheHitchhikersGuideToTheGalaxy'':

* ''Series/TheTwilightZone1959'': A small-scale example occurs in "Third from the Sun" when two scientists and their families steal an experimental spacecraft to flee their home world before a nuclear war that will probably kill everyone else on the the planet.

* ''WebOriginal/OrionsArm'': Old Earth suffered a GreyGoo outbreak known as the Nanodisaster, but that's not why it was evacuated. The outbreak was nullified by an AI named GAIA and it decided humans were the worst threat to Earth so it told us to leave, before it sicced its nanoswarms on us. It was considerate enough to build a fleet of ships first though. In modern times (10,000 years later), Earth is essentially a giant nature preserve, and only a small number of humans are permitted to live on it, subject to GAIA's draconian rules and limitations on their development. GAIA has softened its stance somewhat though, and allows a number of tours to the surface by offworlders.

* In ''Franchise/TheHitchhikersGuideToTheGalaxy'' the colonists aboard the Golgafrincham B Ark were tricked into believing that they were part of one of these, though everyone had heard a different story of what doom was facing Golgafrincha, moon crashing into the planet, planet crashing into the sun, ravenous mutant star goat, etc. The reality was that the B Ark was composed of the "useless" third of the population (telephone sanitizers, hairdressers, middle managers...) and the rest of the planet was getting rid of them. [[spoiler:Ironically, the remaining two-thirds were then wiped out by a plague caused by an unsanitized telephone.]]

* At the start of ''VideoGame/WingCommanderIIIHeartOfTheTiger'', Colonel Blair is listening to a news report that mentions rumors of a doomsday plan for an evacuation of Earth despite Confed claiming officially that the war against the Kilrathi is going well. In the novelisation, Blair scoffs at this as an UrbanLegend the press keeps bringing up. After all it's not like the Kilrathi can't follow them anywhere that Humanity can go.

* ''WebOriginal/{{Serina}}'': To save the sea stewards from the extinction event caused by cataclysmic coal fires, the Observer moves them off of Serina and to a planet that's been terraformed to resemble their old home, and in the process alters their memories so that they do not realize that any transition occurred. Notably, this only extends to the sea stewards -- Serina's other sapient natives, the woolly wumpos and the icefishers, are left behind on their dying world.
