“Amends” by Adrienne Rich is a poem that juxtaposes the natural with the industrial/human. When reading a poem, it's helpful to examine what is literally happening within the text and what is happening figuratively. In the literal sense, a tree is blooming (“a white star, then another / exploding out of the bark”), people are sleeping in their homes (“eyelids of sleeper”), and the moonlight is moving over everything (“it soaks through cracks into trailers”). Figuratively, the ocean lays “its cheek for moments on the sand” and “licks the broken ledge” of the cliff.
The tension picks up in the third stanza (“gash”) and is aimed at industrial devices (“the crop dusting plane” and “sand-and-gravel quarry”). At the end of the poem, the moonlight comes to rest on a sleeping person “as if to make amends,” which personifies the moonlight and implies that there has been a distance or strain between the natural world (the moon) and the human race.
Overall, “Amends” seems to be about a conflict, although you might find evidence of other themes in the text as well.
