Scarcity has become a matter of life and death. From unstoppable forest fires to toxic air quality, plants and animals can no longer survive in the natural outdoors. However, in this world of socialism, new livable cities have been built above the abandoned old ones. These cities are made up of 6 interconnected structures that can produce artificial solar energy, and maintain necessary oxygen levels. Each structure is dedicated to a different component of society with the appropriate energy and climate control needed. These components include agriculture, manufacturing, residential, business/culture, civil, and academic. People can travel between each of them either by personal manual bicycles or electric powered public transit vehicles. These self-sustaining complexes exist all over the globe, each with a maximum population of 30,000 people. In this seemingly unlivable world, humanity is still able to find a way to survive together in a localized, and highly controlled environment.
