On Sunday, April 25, 2010, the Earth Day Network held a "Climate Rally" on the National Mall to encourage Congress to pass strong environmental legislation. During the rally the names of petitioners appeared in lights displayed to the crowd on the Mall.
The Climate Rally featured speakers Reverend Jesse Jackson, "Avatar" director James Cameron, AFL-CIO President Richard Trumka, Olympic gold medalist Billy Demong, and many more.
The rally also featured live music from Sting, John Legend, The Roots, and Jimmy Cliff, among others.
