Happy Earth Day!

I only went out for a walk and finally concluded to stay out till sundown, for going out, I found, was really going in. ~John Muir, 1913, in L.M. Wolfe, ed., John Muir, John of the Mountains: The Unpublished Journals of John Muir, 1938

On December 7, 1972. From NASA: View of the Earth as seen by the Apollo 17 crew traveling toward the moon.
