Stop the sale of styrofoam cups during lunch and break and switch to carrying biodegradable plastic cups instead.
Why is this important?
Not only is styrofoam non-biodegradable, it is also made from a petroleum-based product called polystyrene. Styrene, which makes up polystyrene, has been called a possible carcinogen. Carcinogens are cancer-causing substances. Common contact with styrene can also cause irritation of the eyes, skin and upper respiratory system.
