While many science fiction stories take place in post-apocalyptic wastelands, deep in outer space, or on other planets, another common setting for science fiction is the futuristic city. Compare two different interpretations of urban landscapes, looking first at the flying cars and enormous glass and steel buildings some stories envision, then the gritty, dark dystopia the cyberpunk era introduced. Also consider how depictions of the future cities address and reflect environmental issues, overpopulation concerns, draughts, and other current anxieties.
