I keep losing this site and re-finding it, so am going to put it here.
I like how the author, Marc Balaban, takes the same basic facts as Sara Teasdale, and turns the conclusion into a positive.
(War Time)
There will come soft rains and the smell of the ground,
And swallows circling 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.
