This post is part of Sci-Fi Month 2015, a month long event to celebrate science fiction hosted by myself and Over the Effing Rainbow. You can view the schedule here, follow the event on Twitter via the official @SciFiMonth Twitter account, or the hashtag #RRSciFiMonth.
A common trope of science fiction is to show the Earth greatly transformed, or even completely destroyed, in some way. Our poor planet has been used and abused throughout the history of the genre. Here’s a brief guide to the (post-)apocalypse, or dystopian future, covering books, TV, films and video games.
In these titles, Earth is either destroyed or invaded by aliens. In the latter, it is altered to a state where it is unrecognisable: either through the collapse of society and government, or destruction of large portions of the planet. Sometimes the extra-terrestrials are aggressive, sometimes they are just inquisitive, and other times we’re not even aware of them until it is too late.
These titles show an Earth ravaged by illness, disease or plague, including technological viruses and biological warfare. In many of them, the illness transforms humankind into something else, often zombie or vampire-like creatures.
Science fiction frequently shows how humankind causes its own downfall, often through war or revolt. This is a particularly popular theme in current Young Adult dystopian fiction, although it’s not exactly a new trend in the genre. This is one of the more frightening sides of sci-fi: how we become our very own worst enemies. Occasionally, it shows a glimpse into an alternate future or past.
This could also technically come under ‘Humankind’, because most of the time the natural disasters are caused by people, namely through global warming and climate change. This category includes these as well as other things such as asteroids/meteors, tsunamis, earthquakes etc.
Another terrifying thing about science fiction is how government is often portrayed. Often it is shown as being a totalitarian or ‘Big Brother’ society, a term coined from George Orwell’s 1984. Citizens often have very little freedom, or even free will, having been brainwashed into behaving in certain ways.
Okay, maybe there’s a lot of scary things about science fiction – another one being the very thought of the Earth being overrun or overtaken by machines or artificial intelligence. Many a sci-fi tale tells of the invention of some fantastic new technology, only for it to become sentient and rise up against mankind.
