Since its founding in 1892, the San Francisco-based Sierra Club fought mainly to preserve the nation’s wildlands. In the aftermath of the first Earth Day, the club expanded its range of environmental campaigns, as illustrated on this button from the 1970s.
The button is among the more than 1,500 pin-backed environmental buttons that Gerald H. Meral donated to the National Museum of American History. Meral spent his career addressing natural resource concerns for the California state government and California-based non-governmental organizations. He began assembling his button collection in 1970.
