One of the easiest ways to keep plastic out of the landfill is to refuse plastic straws. Simply inform your waiter or waitress that you don't need one, and make sure to specify this when ordering at a drive-thru. Can't fathom giving up the convenience of straws? Purchase a reusable stainless steel or glass drinking straw. Restaurants are less likely to bring you a plastic one if they see that you've brought your own.
