City of the Future

I see a city one day, Beneath the world, one way, When the air disappears, Climate change is here, Future city below, Earth's undertow, With vertical farms, Surface is harmed, Damage control, A world now old, Future can shock, Giant building blocks, All underground, No air left around, No habitats, you see, In future centuries..... Who will survive? Anything left alive? Below world, the way, I see one city, one day.....
