Wonderful Days

Civilization has been destroyed by war and pollution, but the humans who managed to survive have built the last city: Ecoban. Most natural resources have been depleted, and Ecoban gets its energy from the pollution it generates itself. Ecoban's citizens feel compelled to keep creating this pollution in order to survive. But a group of people believe there are other ways to obtain energy, so they will confront the citizens of Ecoban to clean up the biosphere and see the sky again.
