The Earth Day Special

The Earth Day Special is a television special revolving around Earth Day that aired on ABC on April 22, 1990. Sponsored by Time Warner, the two-hour special featured an ensemble cast addressing concerns about pollution, deforestation, and other environmental ills.

Several cutaways are made to famous fictional characters watching events unfold and discussing what can be done to save the planet.

This special was one of Jim Henson's final performances as Kermit the Frog prior to his death later that year, as well as one of Jeff Bergman's first as Bugs Bunny following the death of Mel Blanc the year prior.

Plot
The episodic narrative, consisting of several individual skits threaded together, focused on an ailing Mother Earth, who falls from the sky and faints, and is rushed to the hospital where she is attended to by Doogie Howser and two other doctors. This special is watched by a married couple named Vic and Paula, and features a host of contemporary celebrities and characters, including Bugs Bunny, The Muppets, Emmett "Doc" Brown, and E.T.
