Imagine this.
There is a planet, where there are people, who live on the surface of the ground.
These people - for good or for bad - live together. They need eachother in order to sustain their daily life. They are also mostly creatures with at least some basic social needs. Due to a severe lack of water, the ground is becoming more and more dry, and cracks appear. These cracks draw lines between the people, separating them from each other. Than the cracs become deeper and the ground starts to move. As the gaps get wider, the people – who are still essentially the same ones with their unsustainable lives on their own and their social needs – become more and more separated.
