Students and Student Organizations engaged in activities during Earth Day Event.


Earth Day

April 22, better known as Earth Day, is always a time to honor Iowa State's many sustainability initiatives, organizations and accomplishments. This year’s event, in consideration of keeping all Cyclones safe and secure, focuses on online opportunities and virtual connectivity – both in Ames, across the US and around the world for the entire month of April. Explore a full Earth Month Calendar to start your month off right!

In 1970, two separate individuals created the concept of Earth Day: peace activist John McConnell, who hosted an Earth Day celebration during the Spring Equinox on March 21, 1970, with help from the United Nations; and U.S. Senator Gaylord Nelson, who hosted an Earth Day celebration on April 22, 1970, which more than 20 million Americans participated in. 50 years later, this beloved holiday is coordinated by the Earth Day Network and celebrated by more than one billion people in 192 countries across the world.
