Earth Day is a worldwide event celebrated annually on April 22 that has since expanded to the month of April. Earth Day was founded in 1970 as a grassroots effort by World War II veteran Senator Gaylord Nelson to raise environmental awareness and involve citizens and communities in creating a cleaner, healthier world. Since the 1990s the Department of the Navy and other military services have celebrated Earth Month annually, organizing events for the community, conducting educational outreach activities, and highlighting Navy/Marine environmental and energy programs.
