Images of Earth Day: Celebrate with events, ideas and incredible photography

40 years ago, Earth Day was conceived as an annual event to inspire awareness and appreciation of the environment. Since then, we have come to realize that Earth Day should, indeed, be every day. But remember: Earth Day isn't just every day, it's today, too. And what better place to celebrate than Planet Green?

Earth Day 2010 Time for Visions, Visionaries and Volunteers For the 40th Anniversary of Earth Day, Planet Green is choosing to look ahead to what's coming. Does the term "green" still apply? Is it the whole story? Or do issues of economy, health, energy and environment cause us to redefine the term? Join the Visionaries Working to Create a Better Future
