Earth Day is celebrated each year on April 22. John McConnell originally proposed the idea to the United Nations in 1969. The first Earth Day in the United States took place April 22, 1970. By 1990 Earth Day became a global campaign concerned with environmental issues.

The Earth Day theme for 2022 is “Invest in Our Planet.”
