When did stores start charging for bags?

Have you ever noticed that, when you go shopping at the grocery store or a department store, they often charge you for the bags they provide to carry your purchases? It's a common practice these days, but have you ever wondered when this trend started? Do you remember a time when stores didn't charge for bags, and they were just given out freely? I'm curious to know, when did stores start charging for bags, and what were the reasons behind this change? Did it have to do with environmental concerns, or was it simply a way for stores to increase their profits? I'd love to hear your thoughts on this topic.
