The title promises a protest poem, and the first line takes that promise back. "I am out of pretty discourse" is a speaker's admission that the supply of eloquence has run dry. "Pretty" is the sharpest word in it. It suggests the decorative language of nature writing, fine phrasing that admires the world without altering anything. The speaker has run out of it, and the poem suggests this is a relief as much as a failure.
What follows is a short, uneasy self-portrait. "I go too far in censuring" shows someone who knows they scold and can hear their own sermon, yet does not quite stop. Then comes the poem's boldest claim: "I am certain that the world / is the true messiah." The line break after "world" leaves it hanging for a moment, as if the speaker were stepping onto firm ground. The idea turns the usual environmentalist stance upside down. We normally talk about saving the planet, but here the planet is the savior, and humans are the ones waiting to be rescued. The word "true" quietly implies false messiahs too: perhaps politics, technology, or the speaker's own persuasive speeches.
Then the certainty collapses in four syllables: "but what will change". There is no question mark, no punctuation anywhere in the poem, so the line can be read several ways. It might be a real question, a shrug, or the start of a sentence that never finishes. Change what, and for whom? If the world is the messiah, why does nothing seem to happen? The poem doesn't answer. Its silence, and the absence of any full stop, is where its feeling lives.
The shape of the stanza enacts this loss of confidence. The first two lines run to eight syllables each, and the lines then shrink: seven, six, and finally four. The lines are not governed by rhyme or a regular beat, and the free verse lets the voice sound like thinking aloud. The opening is built on the repeated "I": "I am," "I go," "I am certain." The speaker is loudly present at first and then fades out, so the last line of the stanza seems to trail off into an anxious silence. The vocabulary also moves from the abstract and Latinate ("discourse," "censuring," "messiah") to plain monosyllables ("but what will change"), as if big language were being stripped away.
The second stanza switches from argument to image, and the poem turns strange and beautiful. "My books open and open" repeats its verb in a way that can be heard as a daily habit, a nervous tic, or an endless offering. The open vowels of "open" and the soft stress give the line a breathing quality, like wings or lungs. Then comes the last image: "thin membranes in a void." Pages are thin, and they are also made from trees, a detail that sits uncomfortably beside the title. A membrane is a living boundary, such as a cell wall or an eardrum, something that lets things through. Yet this one floats in a "void," with nothing on the other side to receive it. The books may be delicate and alive, or they may be hopelessly fragile, and the poem declines to decide.
That refusal is what makes the poem worth reading. Many poems about the environment aim to persuade and end on a call to action. This one doubts whether writing can do the job, and it includes its own books in that doubt. It is honest about the gap between conviction and effect, between being certain and being able to change anything. It also doesn't give up. The books keep opening, and the repetition in "open and open" reads as stubborn persistence as much as futility.
In eight short lines, then, the poem moves from a confession through a bold belief to a fragile image. It lets the reader sit with the unresolved tension of caring deeply about the world while being unsure that words can help it.
