For Neil

Tonight, as I was on a photography walk, I saw the moon and thought it might be appropriate to take a picture of it on the night of Neil Armstrong's death.

I wasn't alive for Armstrong's walk on the moon, but I felt his loss today nonetheless. On one level, I sensed the passing of a momentous time in history. On another level, I realized Armstrong's importance to environmentalism. The moon missions gave us a new perspective on our world, and in doing so, they added momentum to the early days of the modern environmental movement.

Thank you, Mr. Armstrong, for helping change the way we view our planet.
