On April 20, in celebration of the April 22 Earth Day, families nationwide will celebrate our great planet by participating in the Green Apple Festival. If you live near one of these eight cities, you can plug into the music and environmental awareness that will be powering these simultaneous festivities.

Chicago: Lincoln Park Zoo
Dallas: Fair Park
Denver: City Park
Los Angeles: Santa Monica Pier
Miami: Bicentennial Park
New York: Central Park
San Francisco: Golden Gate Park
Washington DC: The National Mall

If you can't attend, do something instead to honor our Earth. Mix it up, like this post recommends. Enjoy a picnic in your favorite local park. Engage in a little eco-running -- tote a trash bag along on your neighborhood jog and pick up any litter you come across. Plant a fruit tree. Start our own compost pile, send a free e-card to friends and family, or simply get outside and marvel at the world around you. And by all means, eat a green apple. It's a Super Food, you know.
