Personally I think this outcome should have been kind of obvious. Stores switched from having an incentive to give out as few plastic bags as possible to save money to having an incentive to give out as many as possible to make money
I also think changing single use bags out for re-usable bags has largely been fumbled as well. The re-usable bags take more energy to manufacture and when they inevitably end up in landfills they take much much longer to break down
The ratio of how many times you have to use a re-usable bag before it offsets the equivalent number of single use doesn't add up to me
There's probably more needed here to make this effective, like bag recycling/return programs or "need a bag take a bag, have a bag leave a bag" sorts of systems
I've been playing around with the idea of a network of "bag rental machines" you could put in grocery stores that people could get bags from for a single shopping trip, and return them to somehow
Somehow I don't think chains making money off selling bags would be very keen on the idea though
