Found on Pinterest search engine. Wendell Berry, 2012, Applegate. This quote is simple yet it helps remind us that we all stand on the earth and we all benefit from its presence. It can be used as a direct quote in my speech, used to enforce the idea that the task of caring for the planet is the responsibility of each and every human being.
