Images of Earth From Above
Images of Earth From Above: Yesterday was Earth Day, a time set aside to increase awareness of the natural environment and the impact of our collective actions. In honor of Earth Day, gathered here is a collection of scenes of our home planet from above, from vantage points we don't see in everyday life. These scenes help show the Earth as a larger system and demonstrate the extent to which human activity has affected it. [39 photos]
