Almost 40 years ago, the EPA started Documerica, a project that coordinated with freelance photographers to capture images of environmental problems, EPA activities, and everyday life in America. Over the project's seven-year lifespan, it compiled more than 15,000 photos. Some of the best are featured below.
From now through Earth Day 2012, EPA is asking for your submissions as a Documerica for a new generation. Photos will be featured on the EPA homepage starting April 15, 2011, and the new collection will debut in April 2012 alongside its 1970s counterpart.
Be sure to check out EPA's Earth Day page for information about the photo project and Earth Day 2011 activities.
