Chicle is a resin that comes from the sapodilla tree, which grows in Central American rainforests. It was once the only way to make chewing gum (synthetic resins are now used in most cases). If sustainably harvested it can help keep the rainforest profitable (and therefore standing). It is one of the ingredients in Make Your Own Chewing Gum kit. Glee Gum also sell ready-made gum using the same ingredient. USA.
