Those ubiquitous plastic shopping bags have a lifespan estimated at 12 minutes but, in fact, live forever, refusing to decompose and eventually pervading the environment as tiny pieces of plastic which may deal to us before the increasingly-immune superbugs do.
PBFW reckon Whanganui folk use around 2.8 million bags each year, and the national consumption has been put at 1.6 billion. That may seem to add up to mission impossible - but no, plastic bags have been banished elsewhere.
Bangladesh, Rwanda, China, Morocco, Holland, France and Macedonia are among countries tackling this issue - and how cool would it be if Whanganui led the way in New Zealand?
It is one small way that an individual can limit pollution and help the environment, and perhaps become part of a significant change.
How hard is it to shove a cloth or fabric bag in your car when you go shopping? And when you've unpacked your groceries, put it back in the vehicle.
And if we want a role model, Waiheke Island - the poor man's Whanganui - has banned plastic bags.
