Today is Earth Day, a day set aside for awarenesss and appreciation of the Earth's environment, and our roles within it - this year marking the 40th anniversary of Earth Day. As a way to help appreciate and observe our environment, I've collected 40 images below, each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it. Happy Earth Day everyone. (40 photos total)
