Trope seen in dystopian sci-fi. A reference, casual or otherwise, to a war fought over diminishing natural resources. Especially significant if it's something we take for granted in advanced societies, like clean water. Of course this is Truth In Television
, as seen in the Middle East. Wars are always going to be fought over natural wealth, but the dystopian aspect comes about because there is an acute shortage
of that resource.
- The Forever War by Joe Haldeman. The Ration War of 2007 (gee, remember that?).
- Implied in the opening montage of Roadwarrior, in which a shortage of oil lead to a nuclear conflict that reduced the Land Down Under to a wasteland plagued by leather-clad hooligans driving gas-guzzling vehicles.
- The B Movie "Battletruck" begins with the words "After the Oil Wars..."
- The Windup Girl by Paolo Bacigalupi. The Coal Wars are being fought between Thailand and Vietnam, in a world in which all the petroleum has been used up.
