Chewing gum became a truly global phenomenon during the second world war when it was included in American GI rations (according to studies, it was therapeutic and increased concentration). After the war, the original tzicle gave way to a polyvinyl acetate – a synthetic plastic that takes up to five years to decompose, and dries into a hard residue that is difficult to remove.
The result has been city pavements covered in a constellation of gum marks – and the sense of an unwinnable war. Although leading gum producers including Wrigley and Mondel?z have backed the Chewing Gum Action Group, an association that helps cities clean gum and organizes anti-littering campaigns, the gum is still widely loved and people are still careless about what they do with it afterward.
