The City of Los Angeles Planning Department drafts an Air Quality Management Plan that calls for the planting of a million trees to help comply with the air-quality standards of the 1970 Clean Air Act. the city estimates that it will require twenty years to plant and 200 million dollars. It turns to TreePeople. In response to this forecast, its recent disaster-relief success, and the Doomsday Report, TreePeople launches the Million Tree Campaign to support Los Angeles residents to plant one million trees in time for the Olympics. The millionth tree is planted in the San Fernando Valley, four days before the 1984 Olympic torch is lit. To celebrate, staff and volunteers go to the mountains and plant 7,000 seedlings in one day.
