"There will come Soft Rains" by Sara Teasdale (1918)

There will come soft rains and the smell of the ground, And swallows circling with their theis shimmering sound; And frogs in the pools singing at night; And wild plum trees in tremulous white; Robins will wear their featheriny 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 will know of the war, not one will care at last when it is done.Not one would mind, neither bird nor tree know, If mankind perished utterly; And spring herself, when she woke at dawn. Would scarcely know that we are gone.
