Earth Day began in 1970 and is now celebrated each year on April 22. Events are held around the world to show support for environmental protection. The week of Earth Day is celebrated as Earth Week, during which activities focus on environmental issues.

The idea for Earth Day began in 1969 at a UNESCO Conference in San Francisco. Peace activist John McConnell suggested a day to honor the Earth and the concept of peace. Earth Day was sanctioned by the United Nations. Shortly thereafter, United States Senator Gaylord Nelson established a United States Earth Day and environmental activist Denis Hayes established an international Earth Day. UNESCO stands for the United Nations Educational, Scientific and Cultural Organization. It is an agency of the United Nations. The purpose of UNESCO is to promote peace through international collaboration. UNESCO uses education, the natural sciences, the social sciences, culture, and communication to pursue its goals.

This is the original Earth Day flag, designed in 1970 by Earth Day founder and pioneer John McConnell, an early leader in the international peace movement. Inspired by the striking first photographs of the Earth taken during America's historic Apollo 10 space mission in 1969.

If Earth Day were a birthday party for Earth, we would need 4.54 billion candles for the birthday cake. That's how many years old the Earth is!
