In Washington, D.C., you can celebrate Earth Day at Union Station, where there will be music as well as other events. The theme chosen by the Earth Day Network for this year is “the face of climate change.”
Google also is observing Earth Day today with an interactive logo on its home page:
The four-season natural setting spells out the word “Google” — from the floral first “G” to the gurgling “g” and “e,” with cavernous “o’s” and an arboreal “l” linking the ever-changing scene.
“Today we are celebrating Earth Day with an interactive doodle that captures a slice of nature’s subtle wonders. We hope you enjoy discovering animals, controlling the weather, and observing the seasons,” writes Leon Hong, who co-created the animation.
