Styrofoam is horrible for the environment, and may be carcinogenic. Yet Dunkin Donuts uses thousands of styrofoam cups. Ask Dunkin Donuts to switch to paper.
Why is this important?
I have spoken to multiple Dunkin Donuts store managers to ask them to stop using styrofoam. They state it is a corporate policy. Only the requests of many people can persuade Dunkin Donuts to change to paper.
