Perhaps appropriate: The famous poem by Sara Teasdale, about a different context, which also lent its name to a short story by Ray Bradbury:
There will come soft rains
--------------------------
There will come soft rains and the smell of the ground,
And swallows calling with their shimmering sound;
And frogs in the pools singing at night,
And wild plum-trees in tremulous white;
Robins will wear their feathery fire
Whistling their whims on a low fence-wire;
And not one will know of the war, not one
Will care at last when it is done.
Not one would mind, neither bird nor tree
If mankind perished utterly;
And Spring herself, when she woke at dawn,
Would scarcely know that we were gone.
