Hong Kong litterbugs shamed in billboard portraits made using DNA from trash

A campaign that used DNA analysis to give a face to anonymous Hong Kong litterbugs, then posted representations of the faces on billboards across the city, has been a big hit on social media. The Face of Litter campaign was launched on Global Earth Day last month for the Hong Kong Cleanup Initiative, organised by online magazine Ecozine and the Nature Conservancy. It was aimed at raising awareness of the extent of littering in the city by pinpointing those responsible and encouraging people to change their behaviour.
