April 22, 2010 is the 40th anniversary of Earth Day. According to Earth Day Network, Earth Day is "the largest secular holiday in the world, now celebrated by more than one billion people."
How are you going to celebrate? You could sign a petition, pledge to take better care of the earth, find a green event (like the big Earth Day Climate Rally planned for April 25th on the National Mall in Washington, DC), or read up about some of the biggest environmental issues facing our planet.
But participating in Earth Day doesn't require a big fancy activity. You can start small. Get out your rubber gloves, find a trash bag, and organize a cleanup of your favorite park, walking trail, or even your own backyard. Every little bit helps.
I thank you and the earth thanks you. Happy Earth Day!
