In recent decades, the term [='=]''EndangeredSpecies''[='=] has been popularized in many media. Endangered Species have become a major international cultural phenomena, with creatures such as the [[ Giant Panda]] becoming global celebrities. While the term 'Endangered Species' probably [[TropeNamer entered common usage]] with the passage of [[ The Endangered Species Act]] in 1973, the concept is [[OlderThanTheyThink far older]]. In 1948, the [[ International Union for Conservation of Nature]] began formally [[ classifying]] certain species as 'endangered', and [[ the beginnings of wildlife conservation]] date as far back as [[OlderThanFeudalism late ancient times]].

To be this trope:
* The EndangeredSpecies, A, must be a type of creature, object, phenomenon, etc., for which there is an apparent distinct possibility they will all soon be [[KilledOffForReal gone forever]].
* A group of creatures, B, who may be the audience rather than a character in the story, or the A's themselves, place a significant value on A's continuing to exist, for no other reason than that the world would be less without them.

* In the past B's either placed little value on the existence of an A or else hated or feared them.
* An InferredHolocaust may have occurred, followed by a MyGodWhatHaveIDone moment. Basically MustMakeAmends at a species-wide level.
* The previously detested SmallAnnoyingCreature or MonsterOfTheWeek becomes DracoInLeatherPants, TheWoobie, etc. in the view of B's.
* A's are not {{Explosive Breeder}}s, so increasing their population is not a trivial task.

A sapient race in terminal decline - not necessarily imminent enough to make them immediately endangered - is a DyingRace. Compare LastOfHisKind, OnlyYouCanRepopulateMyRace, WhatMeasureIsANonUnique. Contrast ExplosiveBreeder.



[[folder:{{Anime}} and {{Manga}}]]
* In ''RosarioToVampire'', [[spoiler: Moka and Kurumu]] view [[spoiler: [[WitchSpecies Witches]]]] this way, and so they ask Tsukune not to be too hard on [[spoiler: Yukari]]. It's later implied that this is also true for many if not most monstrous species, including [[spoiler: Moka's, Kurumu's, and Mizore's]].
* One of ''{{Doraemon}}'''s authors once drew an {{Anvilicious}} comic about humans being hunted to extinction because their bodies were considered to be a potent cure for hairiness (apparently, they don't have Nair in the future). The last two humans end up stranded on an island where a rare lizard (or salamander) was hunted to extinction by earlier humans.
* The eponymous seedship in ''Manga/KnightsOfSidonia'' believe themselves to be the last humans in existence. Earth is long gone, and though there were other seed ships, all contact with them has been lost...

* After ''ComicBook/HouseOfM'' decreased the [[Comicbook/XMen mutant population]] to just a few hundred individuals, Homo superior became this. There was even a storyline with Beast visiting every EvilutionaryBiologist he knew to appeal to them for help restoring the X-gene. The first new mutant birth since M-Day has become a significant plot point in the X-Books.
* Every species from Krypton is an endangered one, if not already extinct in most Franchise/{{Superman}} stories.

* In the ''{{Franchise/Alien}}'' franchise, the RuleOfDrama ensures somebody always seems to want to capture a live xenomorph for study rather than exterminate them...
* In one of the ''{{Tremors}}'' sequels, some humans want to keep at least one Graboid alive.
* Young Spock uses the exact same phrase in the new ''{{Film/Star Trek}}'' [[spoiler: after his planet was destroyed, with roughly 100,000 out of 6 ''billion'' escaping. However many were in space at the time, that's gonna leave a dent.]]
** ''Film/{{Star Trek IV|The Voyage Home}}'' suggests that humpback whales (currently ''not'' an example, although protected by international treaty) will become extinct in the near future. Presumably they'll become one of these along the way.

[[folder: Literature]]
* The Buggers, by the end of ''[[EndersGame Ender's Game]]'', have been reduced to a single Queen. Much of ''Speaker for the Dead'' revolves around finding a suitable home for her so she can start a new hive. This is particularly notable because in ''Game'', the Buggers were hated and feared by humans, and it was Ender's own work that led people to regret their (near) genocide.
** Also note that as the Buggers have a hive mind, the Queen and her hive are all considered to be one individual, so it's a case of [[LastOfHisKind Last Of Her Kind]].
* Pern's dragons were placed in a similar position during the Long Intervals, in that the species' survival depended entirely on the health and fecundity of a single queen.
* ''Literature/InheritanceCycle'': dragons.
* The French novel ''{{Literature/Malevil}}'' [[AfterTheEnd takes place after]] WorldWarIII. As such, all of Emmanuel's livestock are now in danger of extinction, in particular his horses. The only surviving animals were a cave used as a "nursery" and all but one were pregnant. The pig and cow have male offspring and could inbreed to survive. The horse gives birth to a filly, so as far as Emmanuel knows there are three mares left in the world and the horse is doomed to extinction. [[spoiler: There are other surviving animals. Shortly after, Emmanuel captures the region's only stallion, bringing the known horse population to ''four'' and hopefully more in the future]].
* In ''Literature/GalaxyOfFear: The Swarm'', birdlike shreeves are a protected species. The shreeves eat [[ExplosiveBreeder drog beetles]], keeping their population in check so they don't form a HordeOfAlienLocusts. But shreeves are also very fragile, breed slowly, and are not particularly bright. Legends say that killing just one will upset the delicate ecological balance of Sk'rr and give the beetles an edge. [[spoiler: Zak kills one. On the plus side the legend is exaggerated. On the negative side, someone else has been killing thousands.]]

* In ''Series/BabylonFive'', the Dilgar and briefly Humans, during the Human - Minbari war.
** Also the Markab, who [[spoiler: [[KilledOffForReal really did go extinct]] from a plague]]. Humans presumably don't die out from the Drahk plague, but the ones on Earth embody this trope at the start of ''Crusade''.
* ''Series/{{Battlestar Galactica|Reimagined}}'': Humans.
* The [[Franchise/StargateVerse Asgard]], due to millennia of cloning cloned clones and having no original genetic material left. In the series finale they perform a species wide HeroicSacrifice, but apparently there are pockets of them in other areas.

[[folder:Video Games]]
* After conquering a race's last planet in ''{{Spore}}'', any surviving ships will have their label changed from [Name of Species] to Pirate, suggesting that Pirates encountered in the game are actually surviving members of conquered species.
* In ''Franchise/MassEffect'', The Rachni are a sentient, if extremely alien, species of insectoids who were thought to be actually extinct. In the course of the game, you have the choice between setting the last surviving Queen free to let them repopulate, or extincting them entirely. A harder choice than it may seem, since the Rachni went near-extinct due to them embarking on a war with the Citadel Races, causing significant loss of life. In keeping with the trope, you'll have characters - both in your party and further abroad - arguing that you can't justify destroying an entire species, no matter how monstrous it looks, and how much damage it once caused (keeping in mind that the Rachni Wars are ancient history, and this one has PROMISED it won't rise up to threaten the world again.) And some who argue that it's time to 'finish the job.'
** Ironically, the krogan -- who were armed by the Citadel races and sent out into the galaxy to fight the rachni -- suffered a similar fate: the Council deemed them too dangerous, and the krogan were afflicted with an artificially-created plague that all but sterilized their species, which previously bred like rabbits to survive their DeathWorld. In an interesting twist, Mordin reveals that the scientists who created the disease wanted only to ''stabilize'' krogan birthrates, and are now working to make sure the krogan aren't driven to extinction.
* In the ''VideoGame/{{Homeworld}}'' backstory, the Hiigarans.
* Most terrestrial lifeforms in the ''Half-Life'' verse (marine life is said to have gone completely extinct due to billions of leeches and the occasional ichtyosaur swimming around). After a large batch of Xenian lifeforms were teleported onto Earth, a planetary-scale Combine invasion occurred and that's even before the Combine set up their reproduction suppression field which can't be ruled out as being ineffective against anything but humans... If a mini world-war and two decades of global sterility count, then humans might as well be endangered. [[spoiler: At least until the suppression field was shut down and Kleiner urged everyone to "do your part for the revival of our species"]].
* The Ing have nearly been wiped out in ''Franchise/{{Metroid}}''. Since they were created by evil and are evil themselves nobody else seems to be worried about it.
** The Metroids themselves have been hovering around the "completely extinct" event horizon ever since Samus purged their homeworld of them in ''Metroid II''. Of course, given that they're a species of genetically-engineered super-predators, opinions are split as to whether or not the galaxy is better off with or without them.
*** Turns out they kept the X on their homeworld in check, at least.
* A strong theme in the ''{{Oddworld}}'' series. Scrabs and Paramites have been hunted down by Glukkons to make processed food (with Meeches going extinct), Gabbits were hunted down by Vyykers for the wide variety of uses they had with only Munch [[spoiler:and 150 Gabbiar eggs]] left, and Steef were hunted for ''sport'' by Sekto [[spoiler:and of these we only ever see two - Stranger, and Sekto's host body after he's discarded it]].
* Wyverns are endangered in FinalFantasyV. [[spoiler: It was initially believed that there was only one left in the world.]]

* OffWhite: There are no more baby humans being born because of the human white spirit's death. The comic implies this may also lead to the fading away of good, because she was the guardian of good, and the extinction of wolves, because they are a brother species.
* Webcomic/{{Tripp}}: The [[HumanAliens Narvans]], according to [[TinCanRobot Stats]].

* ''WesternAnimation/{{Futurama}}'' had a mission for the Planet Express crew to rescue the animals from a planet which was about to be destroyed. That is where they find Leela's "pet" Nibbler. [[spoiler:Nibbler also eats all the endangered animals]].
* ''WesternAnimation/TitanAE'': Humans themselves after the hostile Drej destroyed the entire planet, leaving the survivors scattered among the cosmos.
* One episode of the WesternAnimation/TheWildThornberrys had a tortoise that was [[ThereIsAnother (almost)]] the LastOfHisKind. Sadly TruthInTelevision, as he was based on a real tortoise called Lonesome George.
* An episode of WesternAnimation/TUFFPuppy had Prof. Birdbrain discover that his species, the blue-bottomed booby, is one and thus is legally protected. He uses this newly-discovered status to go on a crime spree, but ends up foiling himself when he clones a monster booby bird, thus making him no longer endangered and revoking his status.

* Just run a search on the term "endangered species list" and try not to be too depressed. Though you can help by volunteering or making donations to save habitat, provide funding for carers or to buy the animals food.
