Today marks the 40th anniversary of Earth Day -- a time to think about how our actions effect the planet and take steps to clean up our communities.
Everyone from President Barack Obama, to Vice President Joe Biden to R&B singer John Legend to "Avatar" Director James Cameron are coming together to celebrate Earth Day and encourage green living.

Although environmentalists set aside April 22 for Earth Day, cities and towns across the country have been celebrating since last week. The climax of those celebrations will occur Sunday when superstars from around the globe converge on the National Mall in Washington, D.C., for a Climate Rally. Sting, John Legend, the Grateful Dead's Bob Weir, Booker T. Jones, Mavis Staples, the Roots, Passion Pit, former Fall Out Boy lead singer Patrick Stump and Q-Tip will all be there. During the rally, speakers will urge Congress to pass clean-energy legislation in 2010. Music will also be part of the day with Ben Harper and the Relentless7, Guster and Alberta Cross rocking out at the Verizon Wireless Amphitheater in Alpharetta, Ga. The Indigo Girls will play a gig too at the Stefanie H. Weill Center for the Performing Arts in Shebovgan, Wisc.
Finally, one of the greenest rock musicians, Jack Johnson, will hold his environmental benefit, the Kokua Festival 2010, at the Waikiki Shell in Honolulu on Friday and Saturday, with help from supporting acts Ziggy Marley and Taj Mahal.
