Is your roommate a recycling diva? Do you carpool to class? Well smile 'cause you're on green camera! We'd like to applaud your environmentally sound efforts in the best way we know how - by posting your little green mug here on the "Caught on Our Green Camera" page. It's simple, really. Send us a snapshot of you or friends doing something particularly Earth friendly, and we'll upload it here for all the world to see.

Send all photos you'd like considered - one at a time, please! - to Red to Green Camera. And remember, taste - and perhaps, shame - counts. Don't send anything you wouldn't want Mom passing around at the family reunion!
