Environmentalist in Action
One method of advocacy for environmentalists in the 1970’s was a teach-in (an informal lecture). Denis Hayes, organized these events for young people at college campuses across the United States. Eventually, the cause sparked an interest for a national Earth Day. This was the beginning of environmentalism as a cause for the people to advocate for. In this picture, Hayes sits in the official Earth Day office in Washington DC, organizing his lectures.
