In this Oct. 1973 photo provided by the U.S. National Archives, participants check out the Exide Battery Sundancer, an early experimental electric car at the First Symposium on Low Pollution Power Systems Development in Ann Arbor, Mich. The photo is part of Documerica, an EPA project during the 1970s in which the agency hired dozens of freelance photographers to capture thousands of images related to the environment and everyday life in America. Modeled after Documerica, the agency has embarked on a massive effort to collect photographs from across the United States and around the world over the next year that depict everything from nature's beauty to humanity's impact, both good and bad. less
