The Atlantic: 1970s and Dirty America
As the 1960s came to an end, the rapid development of the American postwar decades had begun to take a noticeable toll on the environment, and the public began calling for action. In November 1971, the newly created Environmental Protection Agency (EPA) announced a massive photo documentary project, called DOCUMERICA, to record these changes. More than 100 photographers were hired not only to document specific environmental issues, but to capture images of everyday life, showing how we interacted with the environment and capturing the way parts of America looked at that moment in history. By 1974, more than 80,000 photographs had been produced.
