As Earth Hour made its way across the Middle East, we shared this exclusive image of the fertile Nile River in Egypt as seen from space. Andre Kuipers observed Earth Hour from the International Space Station for the first time in 2012. The images of our planet were shown over the Earth Hour weekend to give some perspective as to what it is we’re trying to save by going beyond the hour each year. Isn’t our world beautiful?
