Dying Earth subgenre

Dying Earth is a subgenre of science fantasy which takes place in the far future at either the end of life on Earth or the End of Time, when the laws of the universe themselves fail. Themes of world-weariness, innocence (wounded or otherwise), idealism, entropy, (permanent) exhaustion/depletion of many or all resources (such as soil nutrients), and the hope of renewal tend to dominate.

The Dying Earth genre differs from the apocalyptic subgenre in that it deals not with catastrophic destruction, but with entropic exhaustion of the Earth. The genre was prefigured by the works of the Romantic movement. Jean-Baptiste Cousin de Grainville's Le Dernier Homme (1805) narrates the tale of Omegarus, the Last Man on Earth. It is a bleak vision of the future when the Earth has become totally sterile. Lord Byron's poem "Darkness" (1816) shows Earth after the Sun has died.

Another early example is La Fin du Monde (The End of the World, aka Omega: the last days of the world), written by Camille Flammarion and published in France in 1893. The first half of the novel deals with a comet on a collision course with earth in the 25th century. The last half focuses on Earth's future history, where civilizations rise and fall, humans evolve, and finally Earth ends as an old, dying, and barren planet.

Another early and more famous science fiction work to utilize the familiar Dying Earth imagery was H. G. Wells's famous novella "The Time Machine" (1895). At the end of this work, the unnamed time traveller travels into the far future, where there are only a few living things on a dying Earth. He then returns to his own time to relate his tale to a circle of contemporaries.
