The viral 'Trashtag Challenge' encourages people to clean up litter

Earlier this week we saw some of the UAE's key figures taking part in a popular social media challenge, as they revealed seven of their favourite books over seven days.

Social media challenges have set off many trends over the years; from amusing ones like the mannequin challenge, to risky ones like the Kiki challenge.

The hashtag - and the action that goes along with it - has been around since at least 2015, when UCO, a Canadian brand of outdoor essentials, announced the challenge and their goal of picking up 10,000 pieces of trash in the year that followed the challenge's introduction.

Shortly after, the challenge was trending worldwide. On Instagram alone, there were more than 25,000 posts with the hashtag #trashtag - variations include #trashtagchallenge and #trashchallenge.

He also shared a before and after photo of a messy area being cleaned up by one young man, and tagged it #BasuraChallenge and #Trashtag - Basura meaning trash in Spanish.

His post has since been shared over 325,000 times on Facebook and thousands of others have been joining in. Dubbed the Trashtag Challenge, it encourages people to pick up litter and post it on their social media accounts while adding hashtags like #trashtag or #trashtagchallenge.

Users across professions have participated in the challenge by identifying places that need cleaning and share selfies after cleaning the place up, also nominating their friends to take up the challenge.

Another collected bags of makeup and clothes dumped in a brook, posting before and after snaps of the area. None of these dumb internet trends, let's clean the planet!'
