Among the outreach programs created to support Earth Day 1990, including parades, proclamations, protests, teach-ins, trash-ins and eco-fairs, Time-Warner produced a celebrity-filled television special for ABC, in the form of The Earth Day Special. Adding to their growing list of Public Service Announcements for the National Wildlife Federation, The Jim Henson Company produced a PSA using Earth Day 1990's popular slogan, "Who Says You Can't Change the World?" The spot featured Kermit the Frog singing his signature song, "Bein' Green."
