The Leavenworth Earth Day Community Fair originated in 2009 through a LIFE2 committee. The LIFE2 organization was a program of Wenatchee River Institute and was headed by Director Jeff Parsons. LIFE2 is no longer active, but it spawned a number of programs and activities that still exist, including the Leavenworth Farmers' Market, the Community Garden, the Shop Local campaign and Earth Day Community Fair.
From the beginning the Fair has been a community celebration of environmental awareness and sustainability. It is held annually on a Sunday near the International Earth Day celebration, which occurs on April 22. For the past eight years, the volunteer planning committee has organized and held this fun and educational afternoon full of activities, music and food for residents of the greater Leavenworth area. It has become a highly anticipated local family event.
