How chewing gum contributes to plastic pollution—and how to reduce its environmental impact

Thousands of tonnes of plastic pollution could be escaping into the environment every year . . . from our mouths. Most chewing gum on sale is made from a variety of oil-based synthetic rubbers—similar to the plastic material used in car tires.

If you find that thought slightly unsettling, you are not alone. I have been researching and speaking about the plastic pollution problem for 15 years. The people I talk to are always surprised, and disgusted, when they find out they’ve been chewing on a lump of malleable plastic.
