Quite stunning that how longs it takes to degrade is used against a paper cup, when, as others have commented. styrofoam doesn’t degrade at all, and what's worse, is when it doesn't end up in a landfill (to take up space for centuries), it breaks up into little pieces that remain in eco-sytems. That is what made me extremely suspicious of this report. Nor does it mention the resources used to obtain the petroleum used in the manufacture of styrofoam. Makes me wonder who is behind this website, and what industry influence and support it represents.

So pause and think about all those little bits of plastic, inside bird and fish and mammal stomachs, and once they die, then still staying in the dirt and water and hanging around for centuries after we’re gone. Or what happens when plastics are burned….There is no dilemma-styrofoam is a bad choice.
