Washington, Mar 15 : American actor Leonardo Dicaprio has signed up for a new campaign to get rid of junk mail.
The eco-friendly actor has signed a petition demanding the U.S. Government acts to grant citizens the right to opt out of receiving unwanted post.
International environmental group ForestEthics came up with the campaign, which has been dubbed as 'Do Not Mail'.
Besides Dicaprio, fellow stars Adam Grenier, Darryl Hannah and Alicia Silverstone have added their signatures to the petition.
"Junk mail is more than an annoying waste of time, it's a waste of our environment!" Contactmusic quoted Grenier, as telling the New York Post.
