This earth pledge appears without attribution in a justice, peace, and environmentally conscious Catholic textbook, Peace through Justice ((Diocese of Cleveland, 1983) by Louise Marie Prochaska. Sister Prochaska, however, does not recall composing it and it may have been circulating for some time in newsletters or other ephemeral works beforehand. On the page following the quoted pledge, the curricular resource recommends contacting the Union of Concerned Scientists for more information, but that recommendation may have more to do with the pedagogical theme of the section that included the text of the pledge. Among the earth pledges, it is unique. Instead of following the form of Bellamy’s Pledge of Allegiance, it uses an ABCB rhyme scheme.
