Article Photos: In '72, EPA battled pollution; now it's politics 5/37

  This photo taken on April 12, 2012, shows a view down Clark Avenue from West 13th Street in Cleveland, Ohio. The same view was photographed in 1973 for the "Documerica" program, 1972-1977, instituted by the then new Environmental Protection Agency to document subjects of environmental concern.
