People are sharing photos of littered areas before and after cleaning them up as part of the viral #trashtag challenge.

The #trashtag challenge dates back to 2015, but gained popularity through a recent Facebook post.

Beaches, parks, nature trails, and other outdoor spaces just got a lot cleaner thanks to a new viral challenge.

The #trashtag challenge involves taking photos of a littered area before and after cleaning it up. Facebook user Byron Román ignited the trend with a viral post.

"Here is a new #challenge for all you bored teens," Román wrote. "Take a photo of an area that needs some cleaning or maintenance, then take a photo after you have done something about it, and post it."

The original Facebook post, which is no longer available, was shared 314,000 times.

The #trashtag hashtag and concept actually date back to a 2015 contest called "The Trashtag Project" sponsored by UCO (or Utility, Comfort, and Originality, an outdoor gear company) where people could post photos of themselves cleaning up litter for a chance to win free outdoor gear.
