The #TrashTag challenge is the best challenge social media has ever created.
Byron Román of Phoenix, AZ, ignited the new trend by calling out bored teenagers in a Facebook post.
"Here is a new #challenge for all you bored teens," Román posted on Facebook. "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."
"Due to teens lately making the news about Tide pods, Bird Box, and now the Momo challenge. Maybe I could inspire a few to do something positive," Román told CBS News.
Román's post has been shared by more than 300,000 people, and it's more than just "bored teens" taking part in the challenge.
People of all ages from all over the world are collecting trash from outdoor spaces in their area and posting before-and-after pictures on Twitter, Instagram, Reddit and Facebook.
#trashtag has been an awesome time world wide flash moment.
From 44bags in Asheville North Carolina, 500 volunteers picking up 8000 lb in South mountain regional Park Arizona, and Hungry cleaning rivers.
For the record, we don't actually think teens are all that bored, considering they are leading the Youth Climate Movement which is gaining in momentum by the day.
However, this is a great example of how the Internet can be leveraged to motivate people to make a positive impact in real life, youth and adults alike.
