Dunkin Donuts, drop the foam cup

Foam cups is not recyclable so they can not be dropped in any recycle collector. Not only that, those cups are not being properly disposed either. Have you ever seen them on the ground when you are walking? I see them so often, and I am finally, decided to start a petition. Dunkin Donuts is a World company and those cups are trashing not just the land of the US.
We are asking the company to be responsible and offer a non-foam cups. It would be perfect if you offer only bio-degradable cups and become the first big company to do it. But even if it is any non-foam cup, it is still better for the environment.
