There are a couple of problems with the attempt to reduce the amount of shopping bags going into the environment, laudable though it is. One, is the vague definition of which bags are "no" and which are "go".
People can still buy lightweight barrier bags, such as the ones from the deli or butchery, along with bin liners, pet waste bags and nappy bags. Also exempt are bread bags and pouches for cooked chicken, for hygiene reasons. Why is sliced bread exempt but not a nan from the local tandoor?
The other issue is that the ban is, admittedly, a "symbolic" gesture and only a drop in the bucket for reduced pollution. That lends itself to suspicions we're being strong-armed into something which is just a little ridiculous.
Ultimately, small gestures can make a difference. Perhaps that's what also resonated so much with the cutaway rogue foodie.
