The Trashtag challenge is one of the internet's most wholesome viral trends, focusing on environmental activism through a simple 'before and after' photo format. While the concept originated as a promotional campaign by UCO Gear in 2015, it exploded into a global phenomenon in March 2019 after a Facebook post by Byron Román urged bored teens to take photos of a littered area and then a photo of themselves after cleaning it up. Unlike many viral challenges that focus on vanity or humor, Trashtag inspired thousands of people worldwide to clear tons of plastic and waste from beaches, parks, and streets. Today, the template is used both to document genuine ecological efforts and as a satirical format to compare messy situations with their resolved counterparts.
