In some ways Italians have it figured out. In other ways, not so much.
Take plastic. They put everything in plastic. I don't understand how they got attached to this means of packaging and distribution. When you buy something that is processed in a factory and sold, such as crackers, it is individually wrapped in plastic and then wrapped again as a whole. When you buy something at the store, say cheese, it is wrapped in plastic. Fruit and vegetables bought from the market are put in plastic. Even if you have your own cloth bag, they put it in plastic first. Just put the damn fruit in my bag. (In Italy, you don't handle the fruit at the market, only the vendor can touch it. So you say how many kilos you want, they pick it out and bag it and then you pay.) The first time we bought prosciutto they put it in a plastic container. It was very pretty , but the second time we bought it, they wrapped it in paper. Much better. More of that, per favore.
There is definitely a sense of disposability within this country. Recycling is available but I am not sure how much of it is used. I see plenty of metal, plastic and cardboard in the trash. I wonder if it is because Italy has been plundered for a very long time and there are very little places of natural wonder. Kids do not go and play in the woods because there aren't any woods. Every inch, just about, has been planted or developed. Their beaches are about the only thing that are still somewhat natural. And let me tell you, they take care of the beaches.
Maybe that is the key. Tell them plastic will ruin their sea if they don't curtail their use of it.
