H a p p y E a r t h D a y 2 0 0 8 ! 38 th Annual Earth Day is Tuesday 22 April 2008 The first Earth Day was held on April 22, 1970. Sen. G. Nelson: “In 1969, I announced that in the spring of 1970 there would be a nationwide grassroots demonstration on behalf of the environment and invited everyone to participate. The American people finally had a forum to express its concern about what was happening to the land, rivers, lakes, and air - and they did so with spectacular exuberance. Earth Day worked because of the spontaneous response at the grassroots level. .... That was the remarkable thing about Earth Day, it organized itself.” Things you can do for the Environment: Attend Richmond’s Earth Day 19 April 10-4 @ Art Works (320 Hull Street) Conserve H 2 O, use E-saving appliances & bulbs, reduce > reuse > recycle, use mass transit, drive a “green” vehicle, volunteer for environ. community service, teach about the Earth and our effects on it
