I don't avoid plastic as much as I could. I do things like bring my own bags for all groceries, but do use some for produce, and reuse the heck out of them, as well as bread bags, ziploc bags that other things come in-things like that. I was at a new supermarket that's kinda a natural food store, and I guess the fact that it's labeled like that really made the rolls of bags stand out. It bothered me. even the bulk items had the plastic tubs as well as bags.
I'd wholeheartedly support the idea of plastic free aisle! That stands out as different and will make people aware of the issue. In America we went from being used to everyone using plastic bags as the norm to a good percentage bringing their own as a habit now. It works
