Humanity has developed rapidly and sustainably. Cities expand absorbing everything in their path. The world population is increasing, currently exceeding 7 billion inhabitants. This growth has consequences: deforestation, habitat destruction, the need to always win over new territories. The Martian Ring meets these needs by offering to colonize new planets.

The idea takes the form of a self sufficient ring incorporating a residential area and a green area which will have a function of the natural habitat and acts as a place for food production but also oxygen.
