Not everyone has a bulk store just around the cornor, mostly they are very far away. So what you can do to reduce your waste and therefore leave a smaller negative impact is to bring your own bags to a shop instead of buying a paper or plastic one every time. Also there are lots of fruits and veggies loose to buy in almost every supermarket. Also to buy cheese or meat you can bring your own container. For bread or sweet and salty pastries I bring my own cotton bag so i don't have to take one from there.
