Northern Lights above Iceland's Eyjafjallajokull volcano, April 22, 2010
Yesterday was Earth Day. Since 1970, it's been a day set aside to remember and appreciate the Earth's environment and all of our roles within it. As a way to help appreciate and observe our environment, The Big Picture
collected 39 recent images, each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it.
