The first widely available biodegradable chewing gum hits British stores today. Chicza Rainforest Gum is manufactured in Mexico from the sap of the chicle tree collected by a cooperative network of chicleros, or gum farmers. Unlike regular gum, Chicza uses no petrochemicals, isn't sticky, and dries up and crumbles to nothingness in about six weeks after a good chew. A pack of lime or spearmint gum sells for $2 a pack.
