Earth 2100 is a [[SpeculativeDocumentary Speculative Docu]] [[DocuDrama Drama]] that originally aired on ABC on June 2nd, 2009, which they chose as the date of birth for the main character, Lucy. Earth 2100 spends equal time between Lucy's story (told through MotionComic illustrations) and interviews with scientists, sociologists, and historians talking about how this worst case scenario will play out.

Earth 2100 begins on [[ExtyYearsFromNow June 2nd, 2100]], with Lucy narrating some of the most significantly horrific things she's seen. Lucy then tells her entire life story, during which we see the world go from a relatively OK state where she lives in a suburban home with a well-watered lawn to a CrapsackWorld in which humanity has been plunged into the Dark Ages.

!!Tropes

* AfterTheEnd: The time at which Lucy is telling her story, on June 2nd, 2100.
* DespairEventHorizon: Lucy hits this when her husband Josh dies trying to close the floodgate.
* DownerEnding: The government has pretty much disintegrated, the Caspian Fever epidemic has killed more than half of the human population, while other parts of the world have wiped themselves out over wars over resources, and most technology has broken down, with only the elite able to use it. Society has become the {{Cyberpunk}} equivalent of the Dark Ages as cities become fortress communities, and the environment will likely take centuries to heal. Lucy herself laments what kind of knowledge to pass onto her grandson in this new world.
* TheEndOfTheWorldAsWeKnowIt: What has happened by Lucy's 91st birthday.
* ExtyYearsFromNow: An interesting variation where, instead of having the work take place in a year of a round figure based on the year of release, they have it take place on the same date a certain number of years into the future.
* ForegoneConclusion: We already know that by June 2nd, 2100, TheEndOfTheWorldAsWeKnowIt has already happened. The plot is basically a matter of finding out how it got to that point.
* GaiasLament
* GreenAesop: Earth is our home, our ''only'' home, and we should treat it accordingly, otherwise we will lose everything.
* JustBeforeTheEnd: Basically the whole 21st century. Over 91 years, we see multiple signs that the world is going to hell in a handbasket that only get worse as time goes on. The world's descent into the CrapsackWorld that Lucy lives in at the age of 91 gets so ''progressively'' bad that the line betweeen [[JustBeforeTheEnd "Just Before"]] and [[TheEndOfTheWorldAsWeKnowIt the actual End]] is kind of blurry.
* MethuselahSyndrome: While the world is steadily growing into [[CrapsackWorld one of the Crapsack kind]] and almost everyone is dying off from diseases and starvation, Lucy has managed to live to the ripe old age of 91, which is longer than the ''present'' life expectancy, even when you're going by that for women. Most amazingly, she still seems to be going strong and is in a physical condition adequate for [[spoiler:leaving New York City to find her daughter and grandson, who are both alive]].
** Justified in that whomever she's telling her life story to had presumably sought her out ''because'' she was so old, and could recall times nobody else remembers.
* TraumaCongaLine: ''Everyone in the world'' goes through this, but we see [[MethuselahSyndrome Lucy's especially long one]].
