Yes slapdash laws do not achieve anything sadly, I know carry some made from recycled bags in my car that I use for grocery shopping, and try to avoid taking plastic bags where i can but some shops insist on giving them to you so you walk the street advertising there store in a bag that is just destined for the trash
Yes your right plastic is mass produced and cheap and prices reflect in what people can afford to buy, and yes convenience also plays a big part, when I go on a long walk and need a drink I will but a bottle of water, often yes it can be recycled and II take my empties till I pass a set of bins which includes a recycling which there are a lot in-the city luckily.
Our office building had banned single use plastics in all the cafeterias, which is a good think, they have water in tin cans and cardboard boxes, but I ust admit i have never bough the ate rain cardboard Carton’s yet myself I am sure it tastes the same just seems odd to me, so I am as guilty s anyone but trying to do my little bit to help
