What's harmful in that? Where are the studies that show that it is harmful? I write this comment on plastic, got to work in a mostly plastic car, drink my coffee out of plastic packaging, have my lunch in plastic containers. I'm sure there should be long term health effects already discovered based on the ubiquity of plastics of all sorts.
