Anime and Manga
- Eureka Seven takes place over 10,000 years after Mankind was forced to leave the Earth due to unintentionally harmful alien life. Somewhere along the line, all of Humanity found a new place to settle down, completely forgetting and/or unaware that they just went back to Earth and live on a new surface that was created by the aliens. The real, perfectly inhabitable Earth, lay below the surface.
- Dragon Ball:
- In Dragon Ball Z, when the Namekian homeworld is set to explode by one of Freeza's attacks, a wish is made on the Dragon Balls to save their lives by evacuating all the Namekians to Earth. Then they promptly have the dragon make them a new one and have themselves beamed there.
- In Dragon Ball GT, 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.
- Gargantia on the Verdurous Planet takes place hundreds or thousands of years after humanity evacuated Earth to escape an impending Ice Age. As it turns out, Earth has since thawed and is habitable once more, but most of humanity has forgotten where it is. It is instead populated by survivors of those humans who were left behind.
- Cowboy Bebop: The Hyperspace Gate explosion fifty years prior to the events of the series 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.
- Super Dimension Fortress Macross: About 3/4 of the way through the series, after fighting a losing battle against the giant alien Zentraedi, the vastly outnumbered humans witness the near-total sterilization of the surface of Earth. Unlike most examples, some of the survivors resettle the Earth and slowly rehabilitate it, with the planet shown to be reasonably thriving in later Macross series like Macross Plus.
- Space Battleship Yamato 2199: A major subplot revolves around "Project Izumo", a plan to create a new human colony out of reach of the Gamilas empire on the verge of destroying Earth. The plan was officially cancelled in favor of the Yamato's quest for Iscandar. However, several moles within the crew are waiting for a chance to mutiny and implement the Izumo plan.
- The Authority do this in one arc, evacuating the planet's entire population so as to cause less collateral damage when fighting a superpowered villain.
- Jor-El, the father of Superman, pushed hard for his fellow Kryptonians to prepare a plan for this when he discovered that Krypton was doomed. For various reasons in various continuities, he is either ignored or sabotaged. In the end, all he could manage was to launch a prototype escape craft that only had room for one: his son.
- Power Girl's origin in the pre-Crisis pre-New 52 universe was also basically this, though unlike her cousin Kal-L, her rocket kept her in suspended animation for 60 years while she aged only 20 years during her travel to Earth.
- Earth 2: In issue #21, Superman's clone stops a space ark carrying the world's most wealthy and powerful individuals from leaving the Earth and rips the ship apart, sending the passengers plummeting to their deaths, with the caption reading, "And the one percent trickle down."
- Project Sunflower: An evacuation is attempted after a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien, crashes on Earth. They use two methods: massive space arks (which are subsequently sabotaged by the "Earth-First" terrorist organization, which is bent on forcing the government to continue fighting rather than evacuate, which they call the coward's way out), and Project Harmonics, intended to find a suitable alternate dimension that humanity can move to. Instead, they wind up finding new allies who, after two separate attempts, succeed in destroying the Black Tide and making it unnecessary to evacuate.
- Deconstructed and averted in The Conversion Bureau: The Other Side of the Spectrum, however. It's made abundantly clear at least three times (twice in the main story, once in Calm) that it's just not going to work. Mostly because of the radiation in space, limited resources (both for making the ship and helping the crew survive), lack of habitable planets, and, as Crowe pointed out, the few colonists that could escape would be nowhere near a match for Celestia if she eventually found them.
- The Elements of Harmony and the Savior of Worlds does have this as an option, though justified because this earth has a few friends who have the technology to make this feasible, and the worlds for humans to escape to.
- In Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover, this is taken up to the level of galaxies. When the Flood comes a-knockin' and you don't have anything strong enough to stop it, the only viable option is getting the hell out.

As part of a peace treaty with the Federation, the Federation agreed to help evacuate Qo'noS within the fifty year time limit of the planet running out of breathable oxygen. However, given that later TV series showed Qo'noS no worse for wear and still the capital of the Klingon Empire eighty years later, it's implied they were able to find some way of reversing the pollution.
- In Jason X, humanity left Earth due to pollution and has resettled on a new planet called Earth Two.
- At the start of Man of Steel, Krypton is about to implode. Jor-El's pleas to evacuate Kryptonians falls on deaf ears, as no one believes that their planet is dying.

- Mission to Mars shows a holographic recording of Martians evacuating their planet for a distant galaxy en masse after a meteor strike renders the planet lifeless, except for a lone ship heading for Earth to seed it with life.
- Earth is polluted and overpopulated in Red Planet. Humanity's only hope is to terraform Mars and re-settle everybody there. The mission is sent to determine why terraforming is failing.

- Interstellar has the remnants of Earth's government trying to find another habitable planet on the other side of a wormhole that opened in Saturn's orbit, as Earth's food chain and atmosphere is rapidly collapsing. "Plan A" intends to use data from a scout ship commanded by Josepher Cooper launched through the wormhole to create an Artificial Gravity drive to lift vast space stations into orbit, whereas "Plan B" assumes the data fails to create a drive, and instead has the scout ship use its stores of seeds, sperm, and embryos to colonize a planet on its own. "Plan A" is revealed to be a sham to give people hope, but Cooper's daughter uses data given to her from a Stable Time Loop to solve the gravity equation. When the scout ship commander returns to Sol over a hundred years later, there are multiple O'neill Cylinders in orbit around Saturn, slowly heading for the wormhole.
- In Last and First Men 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.

- Gianni Rodari has two short stories about aliens from a threatened planet settling on Earth.
- Isaac Asimov's The Currents of Space end with a planet (not Earth, though the idea is mentioned) being evacuated - its sun is about to go nova. Earth is eventually finally evacuated in the broader setting (see the Asimov entry below), but the books leave Earth as a crapsack radioactive expy of Roman Israel and come back to the plot-thread with the last people on Earth already long evacuated and Earth so thoroughly radioactive that nothing can live there.
- In the Isaac Asimov book Robots and Empire which links his Robots series to the Foundation series, a robot causes/allows a radioactive explosion which will slowly poison Earth, forcing the population to expand out into space.
- Happens twice in the Noon Universe:
- The premise of Space Mowgli is that Terrans intend to evacuate the Human Aliens of the planet Panta, whose sun is about to explode, to the planet Ark (named after Noah's Ark).
- In Beetle in the Anthill, the scientists speculate that the entire population of Hope (the planet Abalkin explores in the flashbacks) was evacuated to another (unknown) planet by the Wanderers.
- The Insects From Shaggai (AKA Shan) in Ramsey Campbell's Cthulhu Mythos stories. When their home planet was destroyed by a Mythos abomination, some of them fled to a succession of other planets, finally ending up on Earth.

- The Yuuzhan Vong of the New Jedi Order series underwent a home galaxy evacuation, after massive wars of conquest and then internicine wars they started devastated so much of it that it was rendered incapable of sustaining their civilization (their actual homeworld was destroyed first, and it's speculated, though not fully confirmed, that they were the ones who did it). After traveling through the intergalactic void for millennia, they finally found the Star Wars galaxy - and decided to take over.
- In The Hitchhiker's Guide to the Galaxy 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. Ironically, the remaining two-thirds were then wiped out by a plague caused by an unsanitized telephone.
- In For Your Safety, the Earth is forcibly evacuated by the Groupmind, a distributed AI that determines that the only way to reverse centuries of environmental damage is remove all the humans and move them to a giant Ring World Planet style space station orbiting the Earth.
- In the CoDominium, Earth was 'evacuated' over several decades as the One World Order CoDominium was going to collapse and everyone knew it. CoDom leadership forcibly deported as many people off-planet as possible before the bombs flew, ensuring that even after the Earth was rendered uninhabitable there would be enough human presence on other worlds to ensure humanity's survival.
Live Action TV
- Somewhat inverted in Battlestar Galactica (1978) and Battlestar Galactica (2003), the twelve colonies of Kobol are being evacuated and searching for Earth, which is the "lost" thirteenth colony.
- A surprisingly consistent point of future history in Doctor Who foretells the mass evacuation of Earth around the thirtieth century, to avoid solar flares. The Eleventh meets the Starship UK in "The Beast Below", but it comes up in other episodes as well. In addition the fourth Doctor encounters a wheel-type space station full of sleepers in "The Ark in Space", which is set 20,000 years in the future, implying that it happens more than once.
- The National Geographic special Evacuation Earth has as its premise a wayward neutron star heading towards Earth and attempts to build a Generation Ship to take 250,000 people to Bernard's Star.
- In Defiance the Votan Collective came to Earth when a supernova destroyed their home system. Their sublight ships departed 5000 years ago. They knew Earth was habitable but thought it lacked intelligent life due to the lack of radio signals from it. They were really surprised to be proven wrong when they arrived in 2013. They also sent the Kaziri several thousand years ahead of the Ark fleet to prepare the planet for colonization. When the Kaziri arrives, the crew realizes the planet is populated. In order to prevent the destruction of humanity, several Irathient crewmembers stage a mutiny and crash the ship.
- On the Planet of the Week in the Stargate SG-1 episode "Lifeboat" SG-1 finds a crashed Sleeper Starship built by a human society called the Talthuns, who had evacuated as many people as possible before their planet was destroyed by a coronal mass ejection caused by a "dark star".
- In the Babylon 5 episode "The Deconstruction of Falling Stars", which flashes forward to different eras of humanity's future after the show's time frame, it is shown that humans evacuate Earth one million years in the future, before an impending mysterious artificially-induced nova explosion of Sol.
- Star Trek: The Original Series episode "The Empath". The star of the Minarva system is about to go nova. A group of highly advanced aliens known as the Vians can save the population of only one of the planets in the system. They decide to determine which planet's population will be saved by putting a member of each population through a Secret Test.
- In The Event, it's eventually revealed that the Human Aliens are planning on evacuating their 2 billion population to Earth, as their star is about to make their planet uninhabitable... and are willing to commit genocide to make space for their people.
- In an early episode of First Wave, Joshua reveals that the Gua homeworld is dying, and the conquest of Earth is primarily meant to allow the Gua to re-settle here. Strangely, a later episode has Joshua reveal that at least one other planet (Nostradamus's homeworld) was conquered by the Gua prior to their arrival on Earth. So why didn't they settle there?
- Peter Schilling's "The Noah Plan": The Earth's orbit decays as it drifts towards the sun, and the people on Earth prepare for evacuation by "returning to the universe".
- "The Final Countdown" by Europe, talks about how humans are leaving Earth, because its no longer habitable, with the hope of found a new place to live and new things to discover.
- During The Fall in Eclipse Phase millions of people uploaded their Egos to the sparsely-populated colonies in other parts of the solar system (uploading being the easiest means of space travel), while some others crowded the Space Elevators and crammed aboard ships.
- Classic Traveller, Double Adventure "The Chamax Plague/Horde". In the Back Story, the alien population of a planet was close to being wiped out by a Super-Persistent Predator species called the Chamax. They decided their only chance was to build a fleet of Sleeper Starships to carry all of the remaining aliens to other star systems.
- In the history of Hc Svnt Dracones, during the last days of the Corporate-Terra Firma nuclear war MarsCo evacuated some refugees from Earth who agreed to use the living mutation procedure to become Hemivectors, which helped with the radiation damage. But they stopped after a sleeper agent detonated a nuke on one of the shuttles and destroyed Mars' spaceport. Still, most of the war's survivors were already on Mars, either colonists or having been decanted there.
- BIONICLE: In the Kingdom Alternate Dimension, Matoro fails to revive the Great Spirit Mata Nui, leaving the Matoran Universe in danger and prompt mass exodus onto the island of Mata Nui. Not all beings made it safely, but while many made it to the island, it is only a temporary refuge. The survivors settled quickly and also planned on how to leave the island for the stars.
- Homeworld: The Mothership was meant to be a colony ship before the Kushan even were aware of the threat to their existence, but when the Taiidan incinerated Kharak's atmosphere it became necessary to their survival as a species. Later on, they discover that they were descendants of the losers in a massive war who were forced into one of these.
- Earth, or Lost Jerusalem as it's called, is referred to often in 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 a chunk of the party goes off searching for it, and we're left wanting another sequel.
- The backstory for its spiritual prequel, 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."
- It seems to be a running theme in the Xeno series. Xenoblade Chronicles X 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.
- In Outpost the human race has fled from an asteroid-doomed Earth and colonized a new planet in another star. The plot of the second game (Outpost 2) revolves around the earthling colonists of a new planetnote and how they destroy themselves all over again.
- Another non-Earth example: The D'ni of the Myst series originated on a world called Garternay, which became uninhabitable when its sun began growing dim. Their ancestors fled into a succession of other worlds via their linking books, and have since lost all contact with their abandoned homeworld.
- In SimEarth, if the sapient civilization develops past the "nanotech age", an event called "the exodus" is triggered. All cities, regardless of tech level, are fitted with engines and take off into space. The planet is declared a preserve and left alone, possibly allowing a new sapient species to evolve. The motivation for the exodus is unclear.
- In the RTS Earth 2150, this is the ultimate goal of all three factions, on account of the imminent Earth-Shattering Kaboom. Throughout the campaigns, you not only have to complete missions to cripple your rivals, but stockpile your excess resources in order to build a colony ship to carry you to another world before the countdown expires.
- According to the sequel, all three endings are canonical, which is strange given that it was clearly stated in Earth 2150 that there weren't enough resources to evacuate every faction. The Lost Souls expansion does indicate that a good number of people were left behind, though, and had to find alternative means of escape.
- In Mass Effect:
- This is a common last resort for species attempting to survive a Reaper invasion. Of particular note is a Side Quest to save the Elcor, whose homeworld is being assaulted, in Mass Effect 3. However, this only serves to delay the inevitable, because the Reapers are patient enough to spend centuries exterminating every last trace of all sapient life, no matter where they hide.
- Before the story proper, the quarian race escaped their homeworld to avoid being exterminated by the robot race they created, the geth. Worthy of note is that the geth allowed them to leave to avoid committing genocide.
- Also before the series proper, the drell were rescued from an overpopulated homeworld by the hanar, and felt indebted enough to work as their agents, laborers and assassins, of their own free will. The only downside is that moving from a nearly-desert world to one that's 90% ocean had horrible results on their health - any drell that spends more than a short time outside of their highly-maintained city contracts a terminal lung disease. Alas, in the context of 3, neither the drell nor the hanar get a chance to be extracted from the hanar homeworld, Kahje, if the indoctrinated hanar diplomat isn't stopped from shutting down their defences.
- As Mass Effect 3 proceeds, despite an epic display of resistance by the turians that costs the Reapers quite a lot of time, resources and ships, they are eventually forced to withdraw their surviving military from their homeworld, Palaven, and concentrate on the Crucible. Other races would have been evacuating civilians throughout this, but the turians - as Proud Warrior Race Guys - don't have civilians or even really understand the concept, and so military withdrawal is the closest to an evacuation they'll ever get.
- Freespace: The Vasudan homeworld starts an evacuation partway through the game as the Shivans draw near. Though quite a number escape, the Shivans arrive before they're done and four billion Vasudans die when the homeworld is subjected to Orbital Bombardment. In the sequel, Vasuda Prime is still uninhabitable.
- Starbound has this as the justification as to why humans are traveling the stars. Something took over the earth, and the whole species had to haul ass and find new planets to settle in.
- A variation in the Freelancer backstory. The Alliance evacuation is only partial and not from Earth, since Earth has been in the hands of the Coalition for many decades. By that point, the Alliance only controls a single moon and is about to be crushed by a huge Coalition strike fleet. The five Sleeper Starships manage to break through and jump away, while the remaining Alliance forces try to hold the line. The original trailer for the game also had an alien ship arrive after the exodus and blow up the Sun, making this trope true. Whether this remains a part of the canon is unclear. 800 years after the exodus, Earth and the war that caused the exodus are barely mentioned. People are more concerned with the present.
- The Pilgrims of Endless Space can load up the majority of their population and system infrastructure onto a massive ark, the Fleet Errant, which can then set up a new colony in a separate system. The Fleet leaves behind one population on each planet in the system it departs from, allowing it to rebuild. When the Fleet Errant settles down, it starts off a golden age in the system which massively boosts the production of food, industry, Dust, and science. However, it's generally used more for extremely rapid expansion rather than fleeing danger.
- In Endless Legend, the eight empires of the Lost Colony of Auriga are in a desperate race to get off the planet as its climate collapses; the longer the game goes on, the longer its brutal winters become, until the world is plunged into an Endless Winter at turn 300. Canonically, the Vaulters are the only ones who make it off the world wholesale, appearing in as a playable faction in Endless Space, while other races receive minor roles as Hero Units.
- The backstory to Civilization: Beyond Earth (as the name rather implies). After an unspecified catastrophe known as the Great Mistake, humanity's best and brightest determined that the planet, while still habitable, had passed the "inflection point" and entered a terminal decline. Thus, the Seeding: a venture to launch Colony Ships to a number of alien worlds in hopes of somehow, someday managing to come back and make things right. The Purity victory involves building a portal to Earth to start the flow of evacuees to the new planet. The sequel Sid Meier's Starships takes place in a 'verse where the Seeding is successful.
- According to the manual for Pandora First Contact, Earth is forcibly evacuated by the AIs appointed to watch over it in order to try to restore the planet to its pre-industrial state. All those who did not leave to colonize Nashira stay in the Solar System.
- In Chaos Rings III, the Satellite Base Theia was originally part of a fleet of ships meant to evacuate as many humans as possible when a Planet Eater made its way to Marble Blue. Due to 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.
- In Orion's Arm Old Earth suffered a Grey Goo 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.
- The Simpsons Treehouse of Horror has 2 ships to leave the earth with various stars. One goes to Mars, and the other to the Sun.
- A staple of the Transformers series.
- In Generation 1, the Autobot evacuate Cybertron as it has run out of Energon to support life.
- In Transformers Prime, the Autobots and Decepticons fled Cybertron when it became unsuitable to support them.
- In Superman: The Animated Series, Jor-El had a practical plan to evacuate the entire population of Krypton before it exploded: cast everyone into the Phantom Zone, have someone travel to a suitable planet and release them. However, the thought of being stored with the worse criminals of Krypton and Brainiac's self-serving lies - Jor-El figured this out less than a day before the end, so there wasn't enough time to do so while backing up and evacuating Krypton's archived data(QED Brainiac himself) - made sure it wouldn't be used.
- The Smurfs episode "The Comet Is Coming" pays homage to Superman's origin by having Handy build a rocket for Baby Smurf so that he could escape the Earth's destruction on the night that a rare comet appears in the sky. Fortunately, they find out in time from Papa Smurf that the comet is just simply passing by and Baby Smurf remains with the Smurfs as the empty rocket launches and falls back to Earth, exploding in Gargamel's house.
- In season 2 of Shadow Raiders Planet Fire's world engines are too damaged for it to escape from the Beast Planet so the population hurriedly evacuates to Planet Rock's Battle Moons. Prince Pyrus waiting until everyone else was off before leaving himself, except the Vizier who volunteered to stay behind and try to ram the planet into the Beast.
- It is possible that if we mess things up on the Earth to a sufficient degree, either through war, ecological turmoil or due to circumstances beyond our control, we (or at least the best/brightest/worthiest/wealthiest) would likely have to do this sometime in the future. Though we may avert this if the cause was our own incompetence as our current situation (eg. no Earth 2) may well force us to adapt and develop our civilization in a way that is sustainable and not detrimental to the biosphere.
