I think you article was great, but there was one point you left out. It may take more energy to make a ceramic or stainless steel cup than a styrofoam cup, but once the ceramic cup is made you will use it for years. If you drink 2 cups of coffee a day using a styrofoam cup that is 730 styrofoam cups in just one year. I don't think styrofoam is ever a good option!!! Not to mention the chemicals that may be leaching into your beverage from the styrofoam. And the fact that when they do not end up in the landfill that they end up as a permanent eye sore on coastal shores, where other materials in similar settings would biodegrade. And ingestion or becoming trapped inside causes hazards to marine wildlife.
