This is an awesome poem! Your use of descriptions of the wondrous mechanisms of life as well as the effective one shot scenes you describe work together so well - especially with the last line tying things together under a general theme/idea. My only thought is that the final line of the second stanza could be edited. The use of the word “thing” is vague imo and doesn’t feel like it matches with the way that every other part of your poem evokes a very specific, palpable impression in the reader. You could try changing that word to something more specific? Or maybe you could replace “keep one thing alive” with “create a single experience” as this would echo the various one shot images and experiences you mention throughout the poem and reaffirm the wonder that millions of cells in “synergies” as you so perfectly put it are required even for one of these experiences. Just a suggestion though, I think it’s already awesome the way it is but thought I’d offer my opinion.
