[GreenYes] RE: polyethylene problems??
Thanks for the overkill about benzene, an unrelated compound. If we read the
relevant sections, one will indeed find that ethylene is a rather benign
substance.  
Ethylene Glycol, however, is famous for killing dogs, who like the sweet
taste of antifreeze.  
Polyethylene plastic products are for all practical purposes, inert.
Treating the difference between plastics families as "semantics of degrees,
ie; PVC v. HDPE," demonstrates a basic misunderstanding of chemistry.  
For example; sodium chloride is used everyday as table salt, while pure
sodium is highly toxic and reacts explosively with water.  Who wants to
protest salt?
A deck made of plastic milk jugs is not going to poison Old Faithful.  That
sort of drivel is a major disservice to sensible environmental debate.
