An Alternate Witness

Earthrise is the name given to this photograph of the earth taken by astronaut William Anders on Christmas Eve 1968 during the Apollo 8 mission. Wilderness photographer Galen Rowell called it "the most influential environmental photograph ever taken." Now an editor for the journal Nature reenvisions this photograph as an enviornmental call to action for another generation in this article.

But it is solar energy, indirectly or directly, that will dominate the picture, simply because of its abundance. The Sun delivers more energy to the Earth in an hour than humanity uses in a year.
