Streets across the world are littered with gum, and although many cities have tried and failed to eradicate these sticky circles, Mexico City continues to wage this seemingly un-winnable war
Each night dozens of trucks carrying 15 people depart from Mexico City’s downtown to Francisco I Madero Avenue, the most famous pedestrian street in the capital. Armed with 90C vapour guns called Terminators, the group begins the laborious task of combing the street looking for small, black circles fastened to the ground.
It takes them three days, working in eight-hour shifts, to go through the 9,000 sq metre avenue. By the end, they have removed a total of 11,000 pieces of chewing gum.
