I agree that plastic bags should be discontinued. However, paper bags are a necessity that many people use for liners to their waste garbage cans that food scaps etc. get deposited into, and when full to the non-recyclabe garbage can. With no liner for this garbage, what do you think people will use? Nothing, or force everything down the disposal?? I don't think the garbage man will enjoy dumping a bunch of loose food scaps etc. out of the garbage cans weekly pick up.
This type of thought process falls short of the entended mark in my oppinion!
