A so-called viral challenge has resurfaced and it encourages people to clean up their communities.
BuzzFeed reported that the trend began in 2015 when UCO, a Seattle-based outdoor lighting company, started promoting the project.
According to the company, Steven Reinhold, who is an ambassador for UFO, developed the idea and worked to spread it with UCO. To take part in the challenge, people pick up litter in their area and take selfies in the process.
