The decade America turned green: How the environmental movement gathered speed in the polluted Seventies
These images give an fascinating insight into how far America has come since the 1970s - both in terms of fashion and how we take care of our environment.
The collection of photographs, taken between 1971 and 1977, suggest that Americans were not overly concerned by environmental hazards.
Children splash happily in Louisiana's Lake Charles next to chemical waste, cars lie rusting in ponds and factory chimneys belch smoke over the suburbs of Washington.
However, the environmental movement was slowly gaining momentum.
Stricter emissions tests were introduced for cars, people grew interested in environmentally-friendly technology and individuals began to fight back against pollution from fuel companies.
'Searching for the Seventies: The DOCUMERICA Photography Project,' is currently on show at the National Archives in Washington until September 8.
