Emma Must led a nationwide campaign against the building of roads throughout the country, which would have caused the displacement of hundreds of families and environmental destruction, and also advocated for alternatives means of transportation. She did so through many peaceful protests, chaining herself to bulldozers and joining the organization Alarm UK! and later with Transport 2000 and Global Justice, bringing attention to the issue. Due to her efforts, the British Department of Transport changed its road building policies and the government started proposals for sustainable transport. Photo credit: The Goldman Environmental Prize
