Earth Day was created in 1970. The United States-wide observance was proposed by Senator Gaylord Nelson and occurred on April 22, 1970, with the name coined by ad copywriter Julian Koenig. Independent organizers and early supporters, including John McConnell’s globe-centered concept, helped shape the broader international recognition that followed, and Earth Day is now celebrated in many countries around the world. For a quick timeline: first Earth Day in the U.S. on April 22, 1970; EPA established later in 1970; later global expansion into a worldwide environmental movement. If you’d like, I can pull a succinct, cited timeline or highlight key milestones.[1][3][4][6][8]
