When I was a kid we got milk delivered in glass bottles and then we washed and returned them for re-use. Not plastic bottles
Supermarkets put all their delivery boxes out so you could pack your shopping in them, saving on shopping bags
Fizzy drinks came in glass bottles and with a deposit so you could make a few pennies back, encouraging re-use/recycling
Meat from the butchers was wrapped in a waxy baking paper style covering not in a polystyrene tray covered in plastic. Ditto fish
We've got lazy and regrettably it's mine and my parents generation that have lead the way. We can all complain about kids with their fast fashion and iPhones but they're our kids and we made them with too much carrot and not enough stick
