Posted this because it brought up an interesting math question. It alleges "To ensure that they have lower global warming potential than conventional HDPE plastic bags" the following re-usable bags need to be reused x number of times:
-Paper bags: 3 times
-LDPE (low density poly ethelyene) bags: 4 times
-Non-woven PP (poly proplyene) bags: 11 times
-Cotton bags: 131 times
The op-ed says that number has to be multiplied for every time a plastic bag is re-used for say, picking up dog crap, or as a bathroom trash bag.
