The story
On 22 April 1970, people across the United States joined the first Earth Day. They met in schools, streets and parks to learn about pollution and ask for change.
Senator Gaylord Nelson helped start the idea. Organiser Denis Hayes and many local groups helped turn it into a large public event. EARTHDAY.ORG estimates that about 20 million Americans took part.
People cared about different things: dirty rivers, polluted air or harm to wildlife. Earth Day brought these concerns together. It showed that the environment was connected to everyday life.
One day did not solve these problems. However, the event helped more people see them as shared concerns. Earth Day later grew into an international event. Its first chapter was a national day of learning and action.
