Cigarette butts form slogan, calling for environmental awareness

Sanitation workers use cigarette butts to write out the message "2018 cigarette butt revolution" in a call for greater public environmental awareness in Xi'an, the capital of Shaanxi Province, on March 3, 2018. The cigarette butts were collected by six city cleaners in less than two months, with each worker collecting an average of 500 cigarette butts every day. [Photo: VCG]
