[The Very End]

I think it in the start will be a wasteland, dead and nothing lives after a nuclear war. But then as time goes by, the world heal itself. After many, many years plants starts to grow again, and the animals and insect comes back aswell. After some time the world get a stable eco-system, a stable atmosphere and a world filled with life.
I think that the world will manage to heal itselfe, and best of all - be more stable.
This will ofc not happen over the night, we're talking about maybe millions of years...
