Reusing plastic bags is a wonderful way to help save the environment. OK, so you have got some used plastic bags from the grocery store and you no longer need them. Instead of getting a glass dirty, pour some soda into your plastic bag and put a straw in there. You can try other things too, like peanuts-in-a-bag or spaghetti-and-meatballs-with-garlic-bread-and-a-side-salad-in-a-bag. Get creative!
