->Unless someone like you cares a whole awful lot, nothing's going to change. It's not.

''The Lorax'' is a story written and illustrated by Creator/DrSeuss that was first published in 1971. It is an environmentally-oriented story about a person named Once-ler (shown only as a pair of arms) who caused devastation to the land and was constantly scolded for it by a creature called the Lorax, whose warnings the Once-ler had ignored until it was too late.

''The Lorax'' was adapted into a TV special in 1972 by Creator/DePatieFrelengEnterprises and featured Eddie Albert and Bob Holt as the voices of the two main characters of the story. A [[WesternAnimation/TheLorax feature-length film]] from the producers of ''WesternAnimation/DespicableMe'' was released in 2012, with Danny [=DeVito=] as the title character.

!!Tropes:
* {{Aesoptinum}}: Truffula trees. You know, the ones for which The Lorax speaks. They're used for making Thneeds.
* AffablyEvil: The Once-ler is pretty nice when you're not on his bad side.
* AmbiguouslyHuman: The Once-ler, though only in the sense that you never see any uncovered part of him.
* [[spoiler:TheBadGuyWins: Depressingly so. To put it into perspective, even ''the bad guy himself'' is horrified at his own victory]].
* TheAtoner: The Once-ler.
* BasedOnATrueStory: Sort of. While on vacation in Africa, Seuss was charmed by some strange trees that he, being Dr Seuss, decided to call "Truffula trees". He was later shocked to see them being cut down. It inspired this story, with the Lorax being his AuthorAvatar.
* BitterSweetEnding: Depending on your interpretation. See Downer Ending below for details.
* BlackAndWhiteMorality: Played straight in the original story, with the Lorax being white and the Once-ler and his family being black. The situation of the story is portrayed less so in the AnimatedAdaptation - at one point, the Once-ler argues with himself about what he is doing, ultimately justifying his actions by claiming that if he didn't do it, someone else would, and points out that shutting down his factory would cause all of his workers to lose their jobs; the Lorax admits that he has a point, and also that he himself wouldn't know the answer.
** A possible answer to this is that the Once-ler could've repurposed his factories for something more useful to society, and not so destructive, setting an example for future generations to follow, or to replant truffula trees to replace what they cut, [[SocietyMarchesOn like the real logging industry does nowadays]].
* {{Bowdlerise}}: The Lorax's line "I hear things are just as bad up in Lake Erie" was removed from the book in 1985 after two research associates from the Ohio Sea Grant Program wrote to Seuss about the clean-up of Lake Erie. However, the line is kept in the 1972 TV version (it is spoken by one of the Humming Fish), even in the VHS and DVD releases. At east one British edition of the book lets the line remain, too.
* DarkerAndEdgier: Than other Dr. Seuss books, surprisingly. Its content discusses the effects of using up natural resources, such as trees, and not being able to replace them. However, there was still a glimmer of hope in the form of the last Truffula tree seed and the implication that the trees and the Lorax will return.
* DarkReprise: The TV special has a whole bunch of these as everyone leaves the land.
* DeadpanSnarker: The Once-ler. "Huh? Oh...It's Nature boy. The garden club member."
* {{Determinator}}: The Lorax gets a speech that illustrates this well in his book's 1972 AnimatedAdaptation.
--> I speak for the trees! Let 'em grow, let 'em grow!\\
But nobody listens too much, don't you know?\\
I speak for the trees, and I'll yell and I'll shout\\
For the fine things on Earth that are on their way out!\\
They say I'm old-fashioned, and live in the past,\\
But sometimes I think progress is progressing too fast!\\
They say I'm a fool to oppose things like these,\\
But I'm going to continue to speak for the trees!
* DownerEnding: The story ends with [[spoiler: the forest gone, the animals gone, the settlers gone, the city gone, the factory gone, and the Lorax gone. Only the Once-ler remains, who regrets his actions. However, there is one ray of hope: UNLESS. If the boy can regrow the forest and protect it, maybe the Lorax will come back. What makes this even more depressing in the animated version is that the Lorax tells the Onceler family shortly after they move in that it takes ten years for a Truffula seed to sprout, and ten more years for that seed to grow.]]
* {{Egopolis}}: In the animated version, a town springs up around the Thneed factory, with everything named after the Once-ler ("Onceler Hills", "Onceler Burgers", etc.) There's an OurFounder statue labeled "To Our Beloved Once-ler", but it only consists of a giant hand holding a sign reading "Thneeds".
* TheFaceless: The Once-ler and his family.
* ForestRanger: The Lorax.
* {{Greed}}: Pretty much the cause of the Once-ler's actions, especially when the Thneeds start to take off.
* GreenAesop
* HeelFaceTurn: Nearly happens in the TV special following the Once-ler's second IgnoredEpiphany (see below). But then, it's averted, when the Once-ler's secretary informs him that the price of his company's stock had gone up more than $27. At that point, he goes into his tirade.
* HeelRealization: The Once-ler in the end [[spoiler:after the forest's destruction.]] By the time the boy visits him, he's had plenty of time to reflect on his mistakes.
* HeWhoMustNotBeSeen: The Once-ler and his family (until the film adaptation).
* HopeSpot: The Once-ler managed to save one Truffula seed and gives it to the boy who was listening to his story. Telling him to plant it and start a new forest in the hopes the Lorax and the animals that once lived there will come back.
* HowWeGotHere: The story starts and ends at the place where the Once-ler's Thneed factory once stood, and the Once-ler explains to the boy how it all happened.
* IgnoredEpiphany: The Once-ler does this twice in the 1972 Animated Adaptation of this story. Once when the Bar-ba-Loots were sent away, and again when the Swomee Swans and Humming Fish leave. The latter instance segues into his rant from the climax of the book.
** In the 1st case, he reasons that someone else would do what he's doing so it wouldn't matter either way. In the 2nd, it looks like he's finally gotten the message and is about to turn around. But his secretary had the bad timing of informing about his rise in stock, triggering his greed.
* InformedAbility: In the animated special, the song "Do Do Need a Thneed" lists a number of uses for the Thneeds, including a hammock, a toothbrush holder, a nest, an addition to soup, a grooming item, a dust cloth, a rust remover, a windshield wiper, a viper trap, a tobacco substitute, and a baby's diaper. We never see them used in any of these ways.
** Subverted when we see the first Thneed, as it ''visibly'' changes into a shirt, a sock, a glove, and a hat. Off-screen, it also turns into a pillow and a blanket.
* LookOnMyWorksYeMightyAndDespair: Before the events of the story the Once-ler and his relatives ran a lucrative, though highly destructive, business turning the foliage of the Truffula Trees into Thneeds. When the last(?) Truffula Tree is felled, however, the Thneed factories shut down and the Once-ler's relatives leave for new ventures. By the time the story begins, all that remains of the forest is a field of tree stumps, the ruins of the Thneed factories, wild weeds (call Grickal Grass) growing, and the Once-ler himself. The Once-ler has become a bitter, sad old man who sits around in his home, sometimes telling his and the Lorax's story to passersby in the hope that they may be able to fix his terrible mistakes.
* MeaningfulName: The Once-ler.
* TheMusical: The TV adaptation.
* MyGodWhatHaveIDone: The Once-ler, as he has seen the results of his deforestation efforts.
* NatureSpirit: The Lorax.
* NeverTrustATrailer: The trailers never bother to tell you that the [=TV=] version is a musical with full, three-minute musical numbers.
* [[HumansAreTheRealMonsters Once-lers Are The Real Monsters]]: They're pretty much the stand-in for humans in this story. They consume the territory of all its Truffula Trees and then move on when there is no more, leaving the once flourishing land a deserted polluted mess. (This is made more explicit in the film, where the Once-ler is a human.)
* PollutedWasteland: The land that was once populated by Truffula trees and various animals becomes one when all the trees are cut down, sludge is dumped into the water and pollutants are pumped into the air.
* ScareEmStraight: The entire point of the story is to do this.
* SugarBowl: The land started out as this...
** SugarApocalypse: ..and became this.
* TemptingFate: The Once-ler does this near the end with his rant how he'll just keep growing and growing his company (it's quite jarring in the animated special as he sounds like a madman) [[spoiler: right before the final Truffula Tree is cut down. With no trees, there's no way to make Thneeds, and his company goes broke not long after.]]
* UnusuallyUninterestingSight: "What are you doin' in my tree stump, buddy?"
* VillainProtagonist: The Once-ler.
* VoiceForTheVoiceless: The Lorax, who speaks for the trees.
