Earth Day, observed annually on April 22 to promote environmental protection, is celebrating its 56th year. This year's theme, "Our Power, Our Planet," urges global unity behind renewable energy and clean electricity initiatives.
The movement originated in 1970 when 20 million Americans participated in inaugural events across campuses and public spaces. Senator Gaylord Nelson proposed environmental "teach-ins" to amplify awareness of ecological threats, inspiring a national movement.
By 1990, Earth Day had become a global phenomenon, with over 140 nations joining the observance for its 20th anniversary. Currently, the Earth Day Network coordinates activities with over 1 billion people across 192 countries.
While not a federally recognized holiday, Earth Day remains the largest secular day of protest worldwide, driving public demand for cleaner air, water, and land, and fostering environmental consciousness.
