April 20, 2009--Seen from the sky, a colorful sand sculpture on Islamorada in the Florida Keys encourages people to "Embrace the Earth" as part of Earth Day activities in April 2004.
Earth Day is celebrated worldwide each year on April 22, prompting environmental groups and businesses to pull off a host of sometimes unusual stunts to draw attention to their causes and green initiatives.
For the above sculpture, local businesses each donated U.S. $250 to sponsor a letter. Proceeds supported conservation of rare marine turtles.
